Ibiza sea has hit a new record temperature. A buoy positioned near the island recorded a seawater reading of 33°C, passing the previous record of 31.87°C set in 2024. The measurement lands in the middle of a wider Mediterranean marine heatwave that has affected sea life across the Balearics and beyond this summer. Greenpeace warns of the impacts of ocean warming on the climate and biodiversity.
While the crystal clear water may look more inviting than ever, a swim right now might not bring the refreshment beachgoers expect. Water pushing into the 30s reads closer to a warm bath than a Mediterranean plunge. The unusually elevated temperatures are also placing extra pressure on marine life and underwater ecosystems, from seagrass beds to fish populations that depend on cooler seasonal ranges.
The reading arrives during one of the most talked-about summers in Ibiza’s recent history. The island is battling record-breaking heat on land alongside sea warming, and the combination has intensified conversation around climate resilience, water rationing, and the sustainability of the White Isle’s peak-season model. Recent seasons have already produced a string of similar records, but each new one seems to arrive faster than the last.
