A red Meteoalarm warning for the Split area due to a heatwave is in effect on Saturday, and the extreme heat is visibly raising sea temperatures as well. The State Hydrometeorological Institute (DHMZ) recorded 28.9 degrees Celsius at 2 p.m. at the Zenta measuring station in Split, matching the previous August maximum.
The last time the sea temperature in Split reached this level in August was on August 10, 2017. This year's August 8 has already brought a value that has never been exceeded in the eighth month. Sea temperature measurements in Split have been continuously conducted since 1960.
Unusually warm sea is not only being recorded in Split. On Mljet, at 2 p.m., Malo Jezero reached 30.5°C, and Veliko Jezero 29.8°C. Near Božava, the sea was 28.0°C, in Komiža 27.6°C, in Zadar 27.5°C, while Opatija recorded 27.7°C.
For comparison, at stations with long-term data series, August records are 29.0°C on Rab and in Komiža, and 28.0°C on Hvar.
Although the August maximum has been tied, the absolute record for sea temperature in Split for the entire year remains 29.4°C. That value was set on July 15, 2024, during a strong heatwave that affected the Adriatic at the time. Today's sea was just half a degree away from the highest ever measured value.
All this is happening on one of the hottest days of this summer. For the Split region, a red warning is in effect on Saturday, with maximum air temperatures expected to exceed 36 degrees. On Marjan, 37.8°C has already been recorded, accompanied by thunder. In Split's hinterland, early afternoon brought local showers with thunder, but along the coast itself, extremely hot and mostly dry weather prevailed.
