How long will the extreme heat last?

According to the current forecast, dry and very hot weather with temperatures from 36 to 39 degrees will persist at least until Wednesday 5 August, with a slight easing possibly emerging only in the second half of next week.

Where were the highest temperatures recorded yesterday?

The highest temperature in the region was recorded in Mostar, where 42 degrees Celsius were measured in the shade. In Croatia, the hottest was in the Knin area with nearly 39 degrees.

How to protect yourself from the high UV index?

The UV index is particularly high between 10 a.m. and 5 p.m., so it is recommended to avoid prolonged stays and physical activities in direct sunlight during that period, and to use protective clothing and sunscreen.

Will the relief in the second half of next week be significant?

No. Meteorologist Božarov notes that the influx of fresher air could lower temperatures to only 32 or 33 degrees, which represents just a slight relief, not a true cooling.

Mostar recorded 42 degrees in the shade yesterday, while in Croatia the highest was nearly 39 in Knin. Very high UV index between 10 a.m. and 5 p.m., advising avoidance of the sun.

Summary

Croatia remains under a heatwave with temperatures up to 39°C, locally up to 40°C in the east and south.
Yesterday, Mostar recorded 42°C in the shade, and Knin nearly 39°C.
The weekend and the first part of next week will bring continued heat, with a very high UV index between 10 a.m. and 5 p.m.
A slight easing is possible only from Thursday, when temperatures could drop to 32-33°C.

Croatia is in the midst of a prolonged heatwave, and according to meteorologist Kristijan Božarov's forecast for Klikni.hr, there is no cooling on the horizon. Just yesterday, 30 July, the temperature in the shade in neighbouring Mostar reached a record 42 degrees Celsius. In Croatia, the highest temperature was recorded in the Knin area at nearly 39 degrees, while in central Croatia values rose to 36, and very high figures were also recorded in Osijek and Rijeka.

Today, Friday 31 July, brings no change. Clear, dry and sunny weather is expected with only a light wind. Temperatures in central Croatia will hover around 37 degrees, while in the east and south of the country it could reach up to 40 degrees in places. Particular warning is given to the very high UV index between 10 a.m. and 5 p.m., so it is recommended to avoid prolonged exposure to direct sunlight.

Even Hotter Weekend, No Relief at Night

No change in weather conditions is expected during the weekend of 1 and 2 August. It will remain stable and extremely hot, and the meteorologist predicts that daytime highs could be one to two degrees higher than today's values. Temperatures in the shade will range from 36 to 39 degrees, while night-time lows will remain around 20 Celsius, meaning that even evening hours will not offer a real respite.

"This is a period when the air temperature almost equals body temperature, making it very difficult to find natural cooling," warns Božarov for Klikni.hr.

From Monday to Wednesday, More Hellish Heat

Forecast models show no change for the start of next week either. From Monday 3 August to at least Wednesday 5 August, it will remain dry, sunny and very hot, with daytime temperatures continuing to range between 36 and 39 degrees.

The first signs of a slight easing of the heat may appear only in the second half of the week, around Thursday 6 or Friday 7 August. At that point, there is a possibility that somewhat fresher air will arrive from the north and the Alpine region. This could bring daytime values down to around 32 or 33 degrees. However, as Božarov points out, this will not be a true refreshment, but merely a more bearable heat after the multi-day heatwave.
