Here’s a concise update on the latest information about the UK heatwaves of 2022, with key context and sources.
Direct answer
- The United Kingdom experienced multiple heatwaves in 2022, with the most intense events occurring in July (including a red heat warning and a record high of 40.3°C at Coningsby on 19 July) and an additional heatwave in August. These events were accompanied by extreme heat conditions, “tropical nights,” and widespread impacts.[2][4][5]
Context and highlights
- July 2022: The Met Office issued its first red warning for extreme heat for central and southern England; a national emergency followed as temperatures peaked and heat-health alerts intensified. A record high temperature of 40.3°C was recorded in Coningsby, Lincolnshire, on 19 July 2022.[4][2]
- July 18–19, 2022: 46 weather stations recorded temperatures meeting or exceeding prior UK records, underscoring the severity of the heat event. The heatwave also featured a night with exceptionally high low temperatures ("tropical night").[4]
- August 2022: A second substantial heatwave began on 9 August, with amber warnings covering most of England and Wales and high temperatures peaking around August 13.[1][2]
- Attribution and impact: Studies attributed the July 2022 heatwave to climate change, indicating it became at least 10 times more likely due to human-induced climate change. This aligns with public health warnings and rapid attribution analyses conducted by researchers and the Met Office.[10][4]
Key sources to consult for detailed timelines and figures
- Wikipedia page on the 2022 United Kingdom heatwaves, for an overview of warnings, records, and dates.[2]
- Met Office briefing and guidance documents on the July 2022 heatwave, including the red warning and the national emergency declaration.[5]
- Climate attribution studies and Imperial College London communications on how climate change influenced the 2022 UK heatwave.[10]
If you’d like, I can pull the most up-to-date official summaries or create a simple timeline chart showing daily maximum temperatures and warnings for July and August 2022. I can also provide a brief explainer on how these events influenced policy and preparedness in the UK.

On 12 July, the Met Office issued an amber extreme-heat warning for 17 July, which was extended from 17 to 19 July. It was stated that the high temperatures could extend into the following week.
