UK summer temperatures are falling back from their latest peak after 13 consecutive days above 30C somewhere in the country, but the cooler turn is not expected to bring a clean or permanent end to the unusually warm summer. A northerly airflow should lower daytime temperatures across much of Britain during the weekend of 18–19 July, while isolated showers may develop in a few areas. Most places, however, are likely to remain dry, and longer-range forecasts continue to favour above-average temperatures, particularly across England and Wales, The WP Times reports.
The immediate heatwave is therefore ending, but the wider heat risk remains. A maximum of 31C was recorded at Ross-on-Wye in Herefordshire on Friday, 17 July, marking the 28th day of 2026 on which temperatures exceeded 30C somewhere in the UK. Seven of those days came in May, eight in June and 13 in July. The annual record stands at 34 days, set in 1995, meaning Britain entered the second half of July only six days below that benchmark.
UK summer temperatures ease as northerly air replaces the July heatwave
The short-term change is being driven by a shift in the position of high pressure. During the heatwave, high pressure helped suppress cloud and rain while allowing strong July sunshine to raise temperatures repeatedly above 30C. As that pressure system moves, a cooler northerly flow will spread southwards across the country.
The difference will be most noticeable in central, southern and south-eastern England, where the heat has been longest-lasting. Temperatures that recently reached the low or mid-30s are expected to return closer to the seasonal average, generally settling in the low or mid-20s. That will bring more comfortable daytime conditions and cooler nights, but it does not amount to a sharp cold spell. In sunshine, many places will still feel warm, particularly across sheltered western and southern districts. Cloud is more likely around North Sea coasts and parts of eastern England, especially during the morning. Some low cloud may move inland overnight before breaking during the day. Isolated showers are possible, but the main forecast signal remains predominantly dry.
UK weather outlook by region
| UK region | Short-term temperature trend | Rain prospects | Main uncertainty | Likely effect |
|---|---|---|---|---|
| London and South East | Falling from the low 30s towards roughly 24C–27C | Mostly dry initially; a small chance of showers later | How quickly Atlantic influence reaches southern England | Cooler days, but dry parks and gardens remain under pressure |
| South West England | Heat easing more gradually, locally still warm | A few isolated showers possible, but no widespread rain expected immediately | Southern coastal showers may remain highly localised | Heatwave conditions may linger longest in some districts |
| Midlands | Temperatures moving back towards the low or mid-20s | Mainly dry at first, with showers becoming more possible later in July | Timing and strength of any weather fronts | Fresher conditions, but limited benefit for dry ground |
| Northern England | Cooler air arriving earlier than in the south | Increasing chance of scattered showers | Some areas may stay dry while others receive brief heavy rain | Greater day-to-day variation |
| Wales | Warm sunshine continuing, but below recent extremes | Mostly dry at first; occasional showers possible later | Influence of high pressure may remain stronger in the south | Pleasant summer weather, though rainfall shortages continue |
| Scotland | Temperatures closer to average | Highest likelihood of rain and Atlantic weather fronts | Location of low-pressure systems | More changeable, cloudier and occasionally windy |
| Northern Ireland | Cooler and more variable | Rain chances increasing before much of England | Strength of Atlantic systems approaching from the west | Greater prospect of meaningful rainfall |
The regional divide is important. Scotland and Northern Ireland are closer to the usual track of Atlantic low-pressure systems, while southern England remains more exposed to high pressure extending north-eastwards from the Atlantic.
As a result, the UK may not experience one clear nationwide change. Rain could become frequent in western Scotland while London, Kent and East Anglia remain largely dry.
When will rain return after Britain’s prolonged dry spell
Some rain is likely during the second half of July, but current forecasts do not support the idea of an immediate, nationwide end to the dry period. The most likely sequence is for Scotland and Northern Ireland to become wetter first as low pressure becomes more influential. Rain bands could then cross parts of northern England and Wales, occasionally reaching central and southern England. The Met Office long-range forecast indicates that most places may remain dry initially before conditions become somewhat more changeable. Showers, thunderstorms and occasional longer spells of rain are possible later, although rainfall is expected to be more frequent in northern areas. Southern and south-eastern England are more likely to retain extended dry and bright intervals.
This does not mean the south will remain completely dry. Local thunderstorms could develop, particularly during warm and humid periods. However, convective rainfall is difficult to forecast precisely because it can produce a sharp downpour over one town while leaving neighbouring districts almost untouched. London, for example, had recorded no meaningful rainfall since 5 July, while the next opportunity for light showers was not expected until around 24 July. The capital’s parks and open spaces have already shown visible signs of stress, with extensive areas of grass turning yellow or brown.
Expected development of rain through late July
| Period | Most likely pattern | Areas most likely to see rain | Areas most likely to stay drier | Forecast confidence |
|---|---|---|---|---|
| 18–20 July | Cooler but still largely settled | Isolated parts of northern and eastern Britain | Much of England, Wales and southern Scotland | Relatively high |
| 21–24 July | High pressure remains influential, with limited showers | Scotland, Northern Ireland and isolated northern districts | Southern and south-eastern England | Moderate |
| 25–31 July | More changeable conditions become possible | North and west first; rain may occasionally spread south | South East could retain longer dry intervals | Moderate to low |
| Early August | Mixed pattern of showers, rain bands and warmer dry spells | Northern and western UK most often | Southern and eastern England between weather fronts | Low |
| Mid-August | No reliable daily detail; above-average warmth remains favoured | Dependent on Atlantic low-pressure track | High pressure could rebuild over southern Britain | Low |
The final column matters because long-range forecasting cannot provide the same level of precision as a five-day forecast. Beyond approximately one week, meteorologists focus on the probability of broad weather patterns rather than exact temperatures or rainfall totals for individual towns.
Why isolated showers may not end the UK’s rainfall shortage
A shower appearing in a weather forecast does not necessarily mean that the wider dry-weather problem is over. After a prolonged period without rain, the upper layer of soil can become hard and compacted. A short, intense downpour may then run rapidly over the surface rather than soaking gradually into the ground. Urban areas face a similar problem. Water can flow quickly from roads, pavements and roofs into drains, creating temporary surface-water flooding even when surrounding gardens and parks remain dry below the surface. For reservoirs and rivers, the location of rainfall is also critical. Water companies need sustained rain across upland catchment areas and river basins. A heavy thunderstorm over central London may have almost no effect on a reservoir supplying homes elsewhere in southern England. Central England and the South East recorded an average of zero rainfall across Met Office stations for 14 consecutive days between 2 and 15 July. It was the longest uninterrupted rainless spell in the South East since April 1997 and the longest in central England since June 1996.
Different types of rainfall and what they would mean
| Type of rain | Typical duration | Geographic coverage | Benefit for soil and reservoirs | Main risk |
|---|---|---|---|---|
| Brief isolated shower | 10–30 minutes | Very local | Limited; surface may dry quickly again | Little practical relief |
| Heavy thunderstorm | 30–90 minutes | One town or narrow corridor | Some local benefit, but much water may run off | Flash flooding, lightning and transport disruption |
| Weak weather front | Several hours | Broad regional area | Moderate benefit if rain is steady | Totals may remain too low |
| Slow-moving Atlantic front | Six hours or longer | Large parts of a region | Most useful for soil, rivers and reservoirs | Local flooding if rainfall becomes persistent |
| Repeated days of moderate rain | Several days | Multiple catchment areas | Greatest potential to reduce accumulated deficits | Disruption to travel and outdoor events |
The most useful outcome for the driest parts of England would therefore be several periods of moderate, sustained rainfall rather than one spectacular thunderstorm.
Could another UK heatwave develop in late July or August
Further hot weather remains possible despite the present cooling. The Met Office expects temperatures during the period from late July into the first half of August to remain above normal overall. Hot spells may develop during drier intervals, particularly in southern and south-eastern England. The key question is whether high pressure rebuilds strongly enough over or east of Britain. If it does, warmer air could once again be drawn northwards from France, Spain or continental Europe.
If Atlantic low pressure becomes dominant instead, the UK would experience more frequent rain, stronger winds and temperatures closer to the seasonal average. Both outcomes remain plausible because the current model signals are mixed. The second half of summer may therefore alternate between unsettled Atlantic spells and shorter periods of renewed heat.
What could trigger another heatwave
| Atmospheric development | Result for the UK | Heatwave probability |
|---|---|---|
| High pressure strengthens over Britain | Dry, sunny weather with rising temperatures | High |
| High pressure settles east of the UK | Southerly winds draw hot continental air north | High, especially in England |
| Azores high remains nearby but centred to the south-west | Warm, settled south; cooler and wetter north | Moderate |
| Atlantic low pressure moves repeatedly across the UK | Cloud, rain and near-average temperatures | Low |
| Low pressure stalls west of Britain | Humid southerly air may reach England before rain arrives | Moderate to high |
| Weak, mobile weather systems dominate | Alternating warm days, showers and cooler intervals | Limited risk of a prolonged heatwave |
A heatwave is defined regionally rather than by one national temperature. Different parts of the UK must exceed their local temperature threshold for at least three consecutive days. That means southern England can enter an official heatwave while Scotland, Northern Ireland or northern England remain cooler and more unsettled. It is also possible for temperatures to rise above 30C somewhere in Britain without every region meeting heatwave criteria.
UK records 28 days above 30C before the end of July
The frequency of 30C days is one of the clearest measurements of how persistent the heat has been. By 17 July, the UK had recorded 28 days above 30C during 2026. The breakdown illustrates that the heat was not confined to a single exceptional event.
| Month in 2026 | Days exceeding 30C somewhere in the UK | Significance |
|---|---|---|
| May | 7 | Exceptional early-season heat before meteorological summer |
| June | 8 | Repeated hot spells and periods of extreme heat |
| July to 17 July | 13 | Longest continuous sequence of the year |
| Total | 28 | Six below the annual record of 34 set in 1995 |
The current run ended after 13 consecutive days above 30C. That remains shorter than the 18-day sequence recorded during the summer of 1976, but the comparison is notable because July was only just past its midpoint when the cooler airflow arrived. There is no certainty that the 1995 annual record will be equalled or broken. A wet and unsettled August could leave the total unchanged. Even one more substantial heatwave, however, could bring the record within reach.
Why the summer of 2026 has felt hotter and drier
The intensity of the season cannot be explained solely by the highest temperature recorded on one afternoon. Repeated periods of high pressure have allowed sunshine, dry ground and accumulated heat to reinforce one another. Dry soil contains less moisture available for evaporation, so a greater proportion of solar energy can be used to heat the ground and the air directly. Warm nights have added to the strain because buildings and urban surfaces have had less time to cool. London and other large cities are particularly vulnerable to this effect because concrete, brick and asphalt absorb heat during the day and release it slowly overnight.
The broader climate background is also important. The Met Office says Britain’s recent summers are becoming warmer, while the probability of unusually high temperatures has increased as the climate has warmed. Its seasonal outlook for summer 2026 favoured temperatures above the long-term average, although it did not predict that every week would be hot or dry. A seasonal outlook is not a daily weather forecast. It compares the probabilities of warmer, cooler, wetter or drier conditions across an entire three-month period.
A summer forecast to be warmer than average can still include several cool, windy and rainy weeks. Equally, a changeable August can still contain an intense four- or five-day heatwave.
Wildfire danger persists after temperatures begin to fall
The cooler weekend should reduce heat stress, but it will not immediately remove the wildfire risk. Dry grass, heathland, woodland and agricultural vegetation remain capable of burning even when air temperatures fall below heatwave levels. The most important variable is fuel moisture: vegetation that has dried over several weeks needs sustained rainfall before it becomes substantially less flammable.
Nearly 499 wildfires were recorded across England and Wales between 1 January and 16 July. Although that was below the 748 reported by the same point in 2025, it remained well above the 81 recorded in 2024 and the 242 recorded in 2023. London has already experienced fires linked to the hot and dry conditions, while dry parks and playing fields have provided visible evidence of the prolonged rainfall deficit.
Main risks during the cooler but still dry period
| Risk | Why it remains elevated | What would reduce it |
|---|---|---|
| Grass and heathland fires | Vegetation remains dry despite lower air temperatures | Sustained moderate rainfall |
| Water restrictions | Reservoirs respond slowly to brief showers | Rain across major catchment areas |
| Poor crop and garden conditions | Soil moisture has fallen below the surface | Repeated rainfall over several days |
| Urban overheating | Buildings retain accumulated heat | Cooler nights and cloudier conditions |
| Flash flooding | Hard ground and dry surfaces increase runoff | Gradual rain rather than intense storms |
| Travel disruption | Heat may be replaced by thunderstorms or heavy rain | Stable weather and improved forecast confidence |
The risk profile is therefore changing rather than disappearing. Extreme daytime heat may ease, but fires, water pressure and local flooding from sudden thunderstorms remain credible concerns.
What the BBC Weather and Met Office forecasts mean for the rest of summer
The central forecast message is that the UK is entering a more variable period, not a permanently cool or wet one. Low pressure is expected to become more influential at times, particularly across Scotland and Northern Ireland. This should increase the frequency of rain and cloud in the north and west.
At the same time, the Azores high is likely to remain close enough to Britain to weaken or divert some incoming weather fronts. Its influence should be strongest across southern and south-eastern England. The result could be a divided summer pattern: more frequent rain in Scotland and Northern Ireland, intermittent showers across northern England and Wales, and longer dry, warm intervals in London, the South East and parts of East Anglia. Temperatures are most likely to remain above the seasonal norm overall. That does not mean 30C every day. It means that when temperatures are averaged across a week or month, warmer days are expected to outweigh cooler ones.
Most credible outlook for late July and August
| Forecast element | Most likely outcome | Confidence |
|---|---|---|
| Immediate heatwave | Ends as northerly air spreads south | High |
| Further 30C days | Possible later in July or August | Moderate |
| Widespread rain | Possible, but not guaranteed | Low to moderate |
| Rain in Scotland and Northern Ireland | More likely than in southern England | Moderate |
| Prolonged cool spell | Less likely than above-average warmth | Moderate |
| Further heatwave | Remains possible, especially in England and Wales | Moderate |
| Completely dry August | Unlikely across the whole UK | Moderate |
| Nationwide washout | Not supported by current signals | Moderate |
The greatest certainty concerns the immediate fall in temperature. Confidence becomes lower when forecasting the timing of rain after 25 July and lower again when considering the precise location of any August heatwave.
For that reason, long-range forecasts should be read as a range of probabilities. Statements such as “hot spells possible” do not mean that another heatwave has already been forecast. They mean that the atmospheric pattern remains capable of producing one.
UK summer temperatures are cooling, but the season remains unusually warm
Britain is receiving a temporary break from its latest period of extreme heat, with temperatures returning closer to the July average and the continuous run above 30C coming to an end. The change will be welcomed by people struggling with hot homes, warm nights and difficult working conditions. It will also reduce the immediate pressure on transport systems and public health services. The outlook is less reassuring for water supplies, agriculture and wildfire prevention. Much of England still needs widespread, sustained rain, and the showers currently appearing in forecasts may be too scattered to reverse the accumulated deficit.
The second half of summer is likely to be more changeable than the first. Scotland and Northern Ireland should experience the strongest Atlantic influence, while England and Wales retain a higher chance of dry, warm and occasionally hot weather. Another heatwave is not inevitable, but it remains a realistic possibility. The most probable outcome is a mixed late July and August containing cooler intervals, regional rain, thunderstorms and further periods of above-average warmth rather than a decisive end to summer heat.
