Western Europe experienced its warmest June on record, according to data released by the European Union’s Copernicus Climate Change Service on July 9. The region endured an intense heat wave at the end of the month that broke temperature records, caused disruptions to power supplies, and led to school closures.

The average temperature across Western Europe in June reached 69.3 degrees Fahrenheit. This marks a continuation of a pattern of extreme heat, with the region having faced three significant heat waves in the past three months. Spain and Portugal, among other countries, were affected by another heat wave during the first week of July.

Globally, June 2026 was the second-warmest June recorded, with sea surface temperatures reaching their highest levels since monitoring began. The Copernicus report highlights a trend of increasing frequency and intensity of heat waves, which pose challenges for infrastructure, public health, and environmental systems across Europe and beyond.
