Record Sea Temperatures Off Spain Signal Accelerating Marine Heatwave

Spanish port authorities report unprecedented sea surface temperatures, with a buoy in the Balearic Islands hitting 33.02°C on August 5, and Atlantic waters off Pasaia reaching 28.4°C in June. These records indicate a sustained marine heatwave affecting both Mediterranean and Atlantic coasts, with implications for marine ecosystems and regional climate patterns. The data is preliminary and based on buoy measurements, but consistent with broader warming trends.
