Average sea surface temperatures have reached unprecedented levels in 2025, but researchers from the Balearic Islands Coastal Forecasting and Observation System (SOCIB) have also detected record levels of heat content in deeper layers, with the warming trend extending to depths of 500 meters. This year, the Balearic Sea has experienced temperature anomalies in all seasons. "They were significant in winter and spring and very significant in summer, with record highs in June and July," explains SOCIB researcher Mélanie Juza in an interview with EFE. "This has been the hottest June ever recorded since 1982, which is when we began collecting satellite data," emphasizes the head of the satellite remote sensing facility at the scientific center. Average temperatures in Balearic waters have been between 2 and 4 degrees Celsius above normal, reaching up to 5 degrees Celsius above average in early July. "That's a huge amount, it's a record for the entire region," he emphasizes. In addition to the high regional averages, SOCIB has detected even warmer temperatures locally, reaching 28.5 °C on July 7th, an absolute record for that date. And on July 1st, the Dragonera buoy recorded 31 °C, a total record for the month of July. Besides satellite data and buoys, the agency has other observation platforms, such as underwater gliders and profiling buoys, which record temperature, salinity, and pressure along vertical lines and allow them to calculate "the heat content of the entire water column for the first 150 meters and down to 700 meters." "And in the summer of 2025, in the Balearic Islands, a record for heat content in the deepest layers has been achieved," Juza points out.
