NWS Norman just issued their 1,112th Severe Thunderstorm Warning this year, which is now ~12% higher than their previous year's max of 988. (Glad VTEC implemented 4 digit tracking event numbers!)

During the heatwave in western Europe in August, maximum feels-like temperatures reached up to 45°C in France, 47°C in Portugal, and 49°C in Spain – the threshold for ‘extreme heat stress’ is 46°C 🥵

Summer 2025 is the warmest on record for the UK Provisional Met Office statistics confirm that summer 2025 is officially the warmest summer on record for the UK.

Met Office stats confirm summer 2025 is officially the warmest summer on record for the UK.

The UK’s mean temp of 16.10°C surpasses the previous record of  15.76°C and pushes the summer of 1976 out of the top 5 warmest summers.

Ever wondered how heat stress is changing where you live? With the new Thermal Trace app from #CopernicusClimate and #ECMWF, you can explore “feels-like” temperatures, track heat stress categories and thresholds, and visualise interactive charts for your city.

In recent days, southern Europe has faced heatwaves ☀️ Thermal Trace maps show feels-like temps reaching 46°C – the ‘extreme heat stress’ threshold – in Spain on 14-15 August and 47°C on 11-12 August 🥵 In SW France, feels-like temps reached 45°C – that's up to 14°C above average! 🌡️

Thermal stress = health impacts of exposure to extreme thermal conditions (heatwaves, cold spells)

Use Thermal Trace to monitor heat & cold stress globally (five days behind real time) & explore changes over time 🥵🥶

Tropical nights are on the rise in Europe, offering little relief from daytime heat. The Copernicus Climate Change Service tracks these trends to help keep communities informed and safe.

An interesting comparison of this summer so far with the UK’s infamous summer of 1976 ☀️🥵 This year’s June heat was more widespread across Europe + the UK saw larger temperature anomalies this June, but drought in 1976 was more prolonged and widespread with more extreme water use restrictions 💧

Why are Europe and the Arctic warming twice as fast as the global average? Explore the science behind these regional trends in our latest article.

A map of Europe with the sea coloured based on the sea surface temperature anomalies on 30 June 2025. Annotations mention that most of the Mediterranean basin experienced temperatures well above average, and temperatures exceeded 28°C, more than 5°C above average, in the Gulf of Lion and Ligurian Sea.

A line chart of daily sea surface temperature anomalies in ERA5 from 1979 to 2025 in the western Mediterranean, showing the record-breaking anomalies in June 2025 and highlighting the previous highest anomaly in July 2023.

Exceptional Mediterranean water temperatures in June reduced nighttime air cooling along the coasts & increased humidity, worsening heat stress impacts - some coastal areas saw 10-15 tropical nights (when the temperature doesn’t drop below 20°C) last month, when they’d typically see none in June 🥵☀️🌙

Two significant heatwaves in Europe in June meant that many people experienced more heat stress days than average: 'very strong heat stress' experienced across a lot of southern and western Europe, and part of Portugal saw 'extreme heat stress' 🥵
