July the 27th, 2026 – Following a brief but very welcome period of cooler, fresher and somewhat unstable weather, Croatia is set to face another heatwave with temperatures likely to reach 40 degrees.
After a brief spell of unsettled and sometimes stormy weather, Croatia is preparing for another intense heatwave, with temperatures expected to climb steadily throughout the week and potentially reach 40°C in some inland areas. Index reports that meteorologists are claiming that the hottest conditions are likely to arrive during the second half of the week.
above 35 degrees by the end of the week
Weather conditions are expected to stabilise on Tuesday and onwards. Daytime temperatures will rise each day, with much of the country seeing highs above 35°C by the end of the week. Forecasters say isolated locations could even record temperatures of around 40°C if current forecasts hold.
The Croatian Meteorological and Hydrological Service (DHMZ) has already issued an initial yellow heat warning for Thursday, cautioning that the heat could pose a risk to human health. Meteorologists warn that higher-level warnings may be introduced if temperatures continue to increase as expected.
The upcoming heatwave follows an unusual period of unstable weather that brought thunderstorms, strong winds and a series of strange meteotsunamis along parts of the Adriatic coast. Once the current weather system moves away, a strengthening area of high pressure is expected to bring prolonged sunshine and very little rainfall.
records were broken in june
Forecasters also pointed to this summer’s exceptional conditions. During June, fourteen of Croatia’s 35 main meteorological stations recorded new monthly temperature records, while Split reached an all-time record of 40°C at the Marjan weather station. Staggeringly, even sea temperatures climbed to around 30°C in some areas, highlighting the intensity of this year’s hot summer season.
Authorities are advising residents and visitors to stay hydrated, avoid prolonged exposure to the sun during the hottest part of the day and keep a close eye on vulnerable groups, including the elderly, young children and those with existing health conditions, as Croatia prepares for another spell of extreme summer heat.
