Heat wave in Croatia: Record temperatures up to 38 degrees awaited!

Šibenik, Kroatien - The heat wave in Croatia achieves historical dimensions, as reported on Friday, June 14, 2025. In Šibenik, a record temperature of 36.2 degrees Celsius was measured, which has made this June one of the hottest since the start of the recordings at this measuring station. The Croatian meteorological institute has already called for the warning level red for all of Croatia to draw the population aware of the extreme conditions. The sea temperatures also rise to record values ​​on the Adriatic coast.

Some measuring stations reported water temperatures of up to 29.7 degrees Celsius, and temperatures up to 38 degrees were expected for Split and Dubrovnik for the weekend. These temperatures are not only a challenge for humans and animals, but also have a direct impact on marine organisms. In view of the high temperatures, there is a risk of an algae blossom that is rinsed on the beaches as mucus.

forecasts for the weekend

The weather forecast provides for sunny days for the weekend, with temperatures between 28 and 33 degrees on Saturday and another increase of 1-2 degrees on Sunday. In Gorski Kotar, however, a possible short rain shower will be predicted on Sunday afternoon. Subsequent temperatures will fluctuate between 13 and 24 degrees, depending on the region.

The weather conditions can change noticeably on Monday. Colle may be absorbed by the north, and local rain showers and thunderstorms cannot then be ruled out. The wind will turn north, with a strong bora on the northern Adriatic to be expected.

insight into the changes in the sea

Warming the sea plays an important role in the current weather events. Oceans store over 50 times as much carbon as the atmosphere and absorb 90% of the heat generated by climate change. This increase in sea temperatures has a significant impact on marine habitats worldwide and leads to coral bleach. In recent years there have been several extreme heat waves that also threaten the variety of biodiversity, since high temperatures have a negative impact on the habitat of many species.

The global average temperature was already 1.45 degrees above the pre -industrial level in 2022, and in view of such changes, forecasts indicate increased extreme weather events in Europe. This could also further exacerbate the situation in Croatia, since the heat wave not only harbors health risks, but also endangered the Adriatic ecosystem.

The current situation in Croatia is therefore not only a temporary heat wave, but also reflects the long-term effects of climate change on the beautiful coastal regions and the marine biodiversity, as analyzed by Deutschlandfunk.
