July 2026 stood out not only for global sea-surface temperatures but also for temperatures worldwide during the month. Sea-surface temperatures reached their highest observed level for July, while the month recorded the second-highest global July temperature on record.
Global land-surface temperatures were measured at 16.9°C. This was 0.67°C above the July average for the 1991–2020 period and 1.47°C above the average for the pre-industrial period from 1850 to 1900.
Heat and wildfire impacts in Western Europe
Europe’s average land-surface temperature in July rose to 20.49°C, exceeding the July average for the 1991–2020 period by 0.66°C.
Across Europe, July 2026 was the 11th warmest July in the observational record. June and July 2026 were considered the hottest months in Western Europe since records began, while July ranked as the region’s third-hottest July.
Extreme heat and dry weather brought widespread forest fires to Western Europe. The fires were particularly intense in Spain and France.
Ocean temperatures reach a record
Sea-surface temperatures averaged 20.96°C in July. This made July 2026 the hottest July on record for global sea-surface temperatures, surpassing the previous record set in 2023.
El Niño’s impact on global ocean temperatures is expected to strengthen in the coming months.
