The World Meteorological Organization (WMO) reported that July 2026 was the second warmest July on record globally, according to data from the Copernicus Climate Change Service (C3S), an initiative of the European Union. Average surface air temperatures were 1.47°C above the estimated pre-industrial baseline, with sea-surface temperatures reaching the highest levels ever recorded for July.

WMO Spokesperson Clare Nullis noted that despite it being peak vacation season in Europe and other northern hemisphere regions, many workers and emergency personnel are working tirelessly due to widespread major weather events. These include heatwaves, extreme rainfall, and tropical cyclones.

Western Europe experienced its hottest June–July period on record, with countries such as Switzerland and France facing their fourth heatwave of the summer. John Kennedy, WMO’s head of climate information, attributed low rainfall and heat to drought conditions, low river levels, and heightened wildfire risks. Major European rivers like the Seine, Rhine, and Danube are experiencing low flows.

Nullis highlighted exceptional wildfire activity across western Europe last month, both in terms of area burned and emissions. Fire emissions data from the Copernicus Atmosphere Monitoring Service indicate that year-to-date emissions in France are comparable to or exceed those from the severe fire years of 2022 and 2023.

In North America, wildfires continue to rage in parts of the western United States. Canada reported 591 active fires as of Monday, including 43 classified as out of control.

The WMO emphasized the critical need for stronger forecasts and early warning systems to protect lives and livelihoods amid these escalating climate impacts.
