July saw widespread significantly warmer-than-average temperatures globally, with notable departures exceeding 1°C. Europe and Asia experienced their fourth-warmest July on record. Meanwhile, the sea temperature in certain regions was warmer than usual. For instance, in Mauritius, the average sea temperature in July is around 24°C, which is suitable for water sports like windsurfing and scuba diving. If the sea temperature was 2 degrees higher than usual in this region, it would be approximately 26°C.
In the Mediterranean Sea, sea temperatures vary by location. Some areas like Marina di Ragusa and Marina di Modica have sea temperatures around 25.9°C to 26.5°C during the warmer months, but July temperatures specifically would depend on the location. A 2-degree increase in sea temperature could have implications for marine life and ecosystems.
Global tropical cyclone activity was above average in July 2025, with 14 named storms. The planet also experienced below-average snow cover extent in the Northern Hemisphere and among the four lowest extents on record for both poles.
