This summer is on course to be the UK's hottest since records began, according to the Met Office. Only average conditions are needed for the remainder of August to surpass the record set just last year. Provisional Met Office statistics show that the UK's mean temperature for meteorological summer so far (1 June to 10 August) currently stands at 16.48C, which is 1.88C above the 1991-2020 average. In summer 2025, the mean temperature across the country was 16.10C.

The summer of 2026 has already been extraordinary, marked by a late-spring heatwave setting a new May temperature record, followed by heatwaves in June and a two-week event in July. Further heat spikes have occurred, with many locations reaching heatwave thresholds multiple times. The UK has experienced 37 consecutive heatwave days somewhere in the country this year. The highest temperature recorded so far this summer was 38C in Lingwood, Norfolk, on June 26. An amber extreme heat warning has been issued for parts of England for Thursday, with the possibility of this temperature being equalled or exceeded.

Long-standing heat records have been broken throughout the summer. This year marks the first time on record that temperatures have reached 35C or above in three separate calendar months: May, June, and July. With temperatures potentially exceeding 38C later this week, a fourth calendar month will be added to this total. July 2026 was also the driest on record for both England and Wales since records began in 1836, with Southern England experiencing its driest calendar month ever.

The remarkably warm and sunny summer has led to drought declarations in over two-thirds of England and all of Wales. A total of 45 million people in England are now living in a drought area, and more than 27 million face water use restrictions. Rain is not forecast for most of this week across England and Wales. Forecasts for Sunday suggest some rain may arrive from the Atlantic, with low pressure bringing weather fronts that could bring a spell of rain to some areas, though it is not expected to be particularly heavy or persistent.

Scientists have long warned that summers are getting hotter and are likely to become drier due to climate change. The persistence of high-pressure weather systems over recent months is unusual, but it aligns with scientific projections for summer heat patterns influenced by a changing climate. The current conditions are consistent with evidence that average temperatures are rising globally.

This prolonged period of high temperatures and dry weather has placed significant pressure on water resources across the UK. The National Drought Group has reported that all of England is experiencing these pressures. The scale of water restrictions affects a substantial portion of the population, highlighting the severity of the drought conditions.

While the forecast offers a slight possibility of rain later in the week, it is unlikely to alleviate the widespread drought conditions significantly. The potential for further heat spikes remains, especially with the amber extreme heat warning in place for parts of England. The long-term implications of such extreme summer weather patterns are a key concern for climate scientists and policymakers.

Unresolved questions remain regarding the full extent of the environmental and economic impacts of this record-breaking summer. Further analysis will be needed to assess the recovery of ecosystems and the long-term strategies required to adapt to increasingly extreme weather events predicted by climate models.
