The summer of 2026 in the United Kingdom is proving to be more extreme than the iconic heatwave of 1976, according to data analyzed by the Daily Mail. While 1976 remains a significant national memory, 2026 has surpassed it in several key meteorological metrics, including longer heatwaves, hotter top temperatures, and more consecutive days without rain.
Temperature Records
The highest temperature recorded during the 1976 heatwave was 35.9C (96.6F) on July 3 in Cheltenham. This was actually lower than a previous record of 36.7C (98.1F) set in 1911. In contrast, the current top temperature for 2026 reached 38.0C (100.4F) on June 26 in Lingwood, Norfolk, marking it as the UK's fifth hottest day on record. The all-time UK high remains 40.3C (104.5F) set in 2022. This summer has also seen record-breaking monthly temperatures, with 35.1C (95.2F) in Kew, London on May 26, and 35.5C (95.9F) in Wisley on July 9. While July's peak temperature did not surpass the 1976 record, May and June highs were higher in 2026.
Heatwave Duration and Frequency
Heatwaves in 1976 occurred across May, June, July, and August, with two distinct periods: a 23-day spell from June 21 to July 13, and another 22-day spell from August 6 to 27. The record for the longest heatwave is 39 consecutive days set in 1996. Summer 2026 has recorded a heatwave lasting 37 days, from June 30 to July 27, making it the second-longest on record and longer than the individual spells in 1976. This year has also seen six officially recognized heatwaves, defined as three consecutive days meeting or exceeding local temperature thresholds, compared to two in 1976.
Extreme Heat and Tropical Nights
2026 has set new records for the number of days hitting at least 34C (93.2F) and 35C (95F). There have been nine days reaching or exceeding 34C, surpassing the previous high of seven days in 1976 and 2020. Six days have recorded temperatures of 35C or higher, exceeding the previous record of five held by 1976 and 2020. Furthermore, this is the first year where temperatures have remained above 35C for four consecutive months. The summer of 2026 has also experienced more 'tropical nights,' defined as nights where temperatures do not drop below 20C, with four such nights recorded in June alone, compared to three across the entire summer of 1976. Hastings set a new UK and England record for the highest daily minimum temperature in June at 23.2C.
Drought and Wildfires
While the duration of continuous dry spells in some areas in 2026 has been extreme, with 61 days without rain recorded in parts of Hampshire, the Isle of Wight, and West Sussex, the 1976 drought was more severe and prolonged. The 1976 drought was the driest summer since 1772, beginning in September 1975 and leading to widespread water rationing and standpipes. In 2026, the current dry spell in areas like Wisley, Surrey, has reached 55 days. However, the 1976 event saw 45 consecutive rainless days in some locations and a 16-month dry spell overall.
Despite the differences in drought severity, 2026 has seen a record number of wildfires, with 1,017 incidents recorded in England and Wales so far, matching the total for all of 2025. July was the busiest month on record for wildfires, with 458 incidents.
Subsidence Claims
Both summers have seen an increase in subsidence claims. In 1976, insurance payouts for subsidence reached £60 million. In the second quarter of 2026 alone, home insurers paid out £72 million, with the average claim reaching a record £20,000. This total has already surpassed the 1976 figure, even before accounting for inflation.
Average Temperatures
Provisional data indicates that the mean temperature for summer 2026 so far, from June 1 to August 10, stands at 16.48C. This is higher than the then-record average of 15.7C set in 1976 and the current record of 16.12C from 2025. For England and Wales, temperatures have been over 2C above average, making a new record for the summer mean temperature highly probable.
