Croatia was hit by a powerful heatwave today, August 4, 2026, prompting the State Hydrometeorological Institute (DHMZ) to activate a red meteoalarm for seven regions. By 1 PM, temperatures had already surpassed 35 degrees Celsius at numerous measuring stations, with the highest reading recorded in the continental part of the country.
According to DHMZ data, the day's record holder is Bilogora, where a scorching 37.5°C was measured at 1 PM. Close behind are Osijek-Čepin with 37.2°C, and Daruvar and Slavonski Brod, both at 36.8°C. In the capital, at the Zagreb, Grič measuring station, the mercury climbed to 36.5°C, while Knin recorded 36.4°C.
The list of places with extreme heat doesn't end there. Kutjevo reached 36.2°C, while Krapina and Ogulin both hit 36.1°C. Gorice near Nova Gradiška and Gradište measured a round 36.0°C, and Pazin on the Istrian peninsula saw 35.7°C.
The red alert, which signifies extremely dangerous weather conditions, has been issued for nearly all of Croatia. The most severe situation is expected in the Osijek region, where temperatures could exceed 39°C by the end of the day. The Karlovac region is forecast to see temperatures above 38°C, and the Zagreb region above 37°C.
The rest of the country won't be spared either. The Rijeka region is expecting temperatures above 36°C, while the Gospić and Split regions will see maximums exceeding 35°C. Slightly "milder," but still very hot, conditions are expected in the Dubrovnik area, with forecasts of over 34°C.
Due to the extreme conditions, DHMZ is warning citizens to take protective measures. Special emphasis is placed on protecting children, the elderly, and those with chronic illnesses. Citizens are advised to avoid being outdoors during the hottest part of the day, to stay well-hydrated, and to follow instructions from authorities. In addition to health risks, DHMZ also warns of potential infrastructure failures caused by the high temperatures.
