Spring 2026 saw an extraordinary late-May heatwave that delivered the warmest spring on record for England and Wales and the third warmest for the UK, combined with below-average rainfall in many areas and notable impacts on water supplies and agriculture.
The United Kingdom experienced a notably warm and largely sunny spring, culminating in an extraordinary late-May heat episode that helped deliver the warmest spring on record for England and Wales and the third warmest spring for the UK by mean temperature.
Across the season, all three meteorological spring months—March, April and May—ranked among the UK’s top ten warmest since 1884, and several daily station records were broken during the late-month surge.
The heatwave at the end of May was particularly remarkable: some monitoring sites recorded six consecutive days above 30°C, and successive provisional station records were set at Kew Gardens with highs of 34.8°C and then 35.1°C, while Heathrow reached 35.0°C.
These extremes pushed seasonal averages upwards and produced unusually high mean maximum and overnight minimum temperatures.
Key temperature statistics and how the season compared historically
Provisional figures from the Met Office and the HadUK-Grid dataset show the UK mean spring temperature at 9.33°C, with regional breakdowns of 10.41°C for England, 9.73°C for Wales, 7.46°C for Scotland and 9.06°C for Northern Ireland.
England’s spring mean surpassed the previous record of 10.23°C, making the three warmest springs for England 2026, 2026 and 2026. In total, forty counties recorded their warmest spring for mean temperature since records began in 1884.
Monthly progression and notable records
The season unfolded with a joint tenth warmest March for the UK, a seventh warmest April, and a May that ended as the joint third warmest on record. May contained a rapid transition from an unsettled, cool start to a dominant high-pressure pattern that produced the exceptional late-month heat. Southern England recorded its warmest May for mean temperature, and 27 counties reported their warmest May since 1884.
Rainfall, sunshine and regional contrasts
Spring rainfall for the UK was around 14% below the long-term meteorological average, but this average hides strong regional contrasts. England received only 65% of its typical spring rainfall, with Northern England near 90% of average while Southern England dropped to about 50%. Counties in the southeast and east—such as Suffolk, Kent, Essex and Cambridgeshire—saw roughly one third of their usual seasonal rain.
At the same time, the UK experienced well above average sunshine totals. The season ranked as the fourth sunniest spring since 1910 for the UK as a whole; England recorded its third sunniest spring, Wales was joint eighth and Scotland ninth. These elevated sunshine totals reinforced the warm, settled conditions for many areas.
Regional wetness and agricultural impacts
Scotland was the only nation within the UK to finish spring wetter than average, with parts such as the Western Isles and Ross and Cromarty recording some of their wettest springs on record. Conversely, the dry conditions in parts of England contributed to falling river flows and declining reservoir levels. Water managers have warned that, although no parts of England were officially in drought at the time of reporting, the risk rises if the dry spell continues.
Industry experts noted early effects on crops: the Agriculture and Horticulture Development Board reported that drier April–May conditions reduced winter cereal condition scores and left many spring crops struggling where soil moisture reserves were depleted. A later return of wetter weather during mid-May helped some crops, but the late-May heat increased stress, including visible leaf rolling in wheat. There is concern that yields could be affected if precipitation does not improve in the following weeks.
Heatwave health alerts and record overnight temperatures
The late-May heat also led to public health responses. Authorities extended amber-level heat alerts in several English regions as forecasts anticipated daytime peaks near 35°C, and some monitoring sites recorded consecutive record-breaking May minimum temperatures—so-called tropical nights—with nighttime lows not dropping below around 21.3°C at specific locations. The UK Health Security Agency and local services issued guidance as demand for water rose and emergency responders dealt with incidents including wildfires and heat-related health effects.
Climate context and attribution
Scientists emphasised that while individual events involve natural variability, long-term warming trends are increasing the likelihood of records being exceeded. Climate attribution research cited by the Met Office has shown the probability of surpassing historical May temperature records has increased substantially as greenhouse gas concentrations have risen, making events that were once very rare now more likely.
The season’s provisional statistics and regional breakdowns are based on the HadUK-Grid interpolated dataset, which maps observations onto a 1km-by-1km grid and extends historical coverage back to the 19th century. These datasets allow comparison with long-term records and help contextualise the recent run of unusually warm springs.
