The United Kingdom is increasingly likely to experience its warmest summer since national records began in 1884, as persistent heat continues across much of the country, according to the UK Met Office.
Provisional Met Office figures show that the UK’s mean temperature for the summer so far has reached 16.48°C, around 1.88°C above the 1991–2020 seasonal average. The figure covers the period from June 1 to August 10 and places 2026 ahead of the pace needed to challenge the existing national summer temperature record.
The heat has been particularly pronounced in England and Wales. England has recorded a mean summer temperature of 18.19°C, approximately 2.46°C above average, while Wales has recorded 16.80°C, around 2.17°C above average. The Met Office said temperatures during the remainder of August would have to fall significantly below seasonal norms to prevent both countries from challenging their existing records.
The prolonged warmth forms part of an exceptional period for Britain’s climate, with repeated spells of high temperatures pushing seasonal averages upward. The Met Office has described a record-breaking summer as increasingly likely, although the final ranking cannot be confirmed until the meteorological summer ends on August 31.
The conditions also reflect a broader pattern of unusually intense summer heat across Europe, where high temperatures and dry conditions have increased pressure on water supplies, agriculture and infrastructure while contributing to elevated wildfire risks.
With several weeks of August still remaining, forecasters will continue monitoring temperatures closely. Unless Britain experiences a sustained period of substantially cooler weather, summer 2026 could enter the record books as the hottest the country has experienced in more than 140 years of observations.
