Heatwaves in Croatia
What to say about heatwaves in Croatia? There are usually 2 -3 heatwaves each summer and they last for a few days. Heatwaves are becoming more frequent due to climate change and they usually occur in July and August . These extreme conditions can push temperatures above 40°C (104°F) , particularly in inland regions and urban areas where heat is trapped by buildings and asphalt.
Common Heatwave Effects:
High humidity, makes the temperature feel even hotter.
Warmer nights, often staying above 25°C (77°F) . If you don’t have air conditioning in your accommodation, you’re going to have sleepless nights. But then you can go out stargazing, which is a nice summer activity in Croatia.
Increased risk of sunburn and dehydration. Avoid sunburns at all costs since they can ruin your vacation in Croatia.
Strong UV radiation , requiring sun protection. Always wear a hat, that’s our best advice.
