ZAGREB, 29 July 2026 – Croatia is preparing for a period of extreme heat as the Croatian Meteorological and Hydrological Service (DHMZ) warns that a powerful heatwave will affect much of the country into the first week of August.
According to the latest forecast, a strong anticyclone over south western and central Europe will continue to draw very warm and dry air across Croatia, bringing widespread hot and very hot conditions.
From Saturday, daytime temperatures are expected to reach between 35°C and 40°C in many parts of the country. The heatwave is also expected to bring warm nights, with little opportunity for temperatures to cool.
Along the Adriatic coast, overnight temperatures are forecast to remain around or above 25°C, increasing heat stress and reducing relief from the daytime heat.
The highest level of heatwave risk is expected to expand over the coming days.
By Thursday, a very high risk is forecast for the Rijeka region, with high risk extending to Zagreb, Split, Dubrovnik and parts of inland Croatia.
On Friday, very high risk remains for Rijeka and expands to Dubrovnik, while Zagreb, Karlovac, Knin and Split remain under high risk.
For the weekend, red weather warnings have been issued for several regions, including Zagreb, Rijeka, Split and Dubrovnik, as temperatures continue to climb.

DHMZ meteorologist Krunoslav Mikec said the current weather pattern is expected to persist through much of the first week of August, with temperatures possibly rising even further. He added that the weather service will continue updating warnings as conditions develop and urged the public to monitor the latest forecasts.
Croatia’s Civil Protection Directorate has also issued advice for residents and visitors during the heatwave.
People are urged to avoid spending time outdoors during the hottest part of the day, particularly between 10 am and 5 pm, stay well hydrated and wear light, breathable clothing. Extra care is advised for older people, young children, pregnant women, those with chronic health conditions and anyone working outdoors.
Authorities also reminded the public never to leave children, older people or pets inside parked vehicles, even for a short time, and to seek medical attention if symptoms of heat exhaustion or heatstroke develop.
