Croatia's Coldest Morning Amidst National Heatwave

While much of Croatia grappled with an intense heatwave on June 29, 2026, prompting red and orange weather alerts for several regions, the small village of Crni Lug experienced a surprisingly cool morning. At 6 a.m., the State Hydrometeorological Bureau recorded a low of just 13 degrees Celsius in Crni Lug, making it the coldest spot in the country. Ličko Lešće was only slightly warmer at 14 C.

In stark contrast, Senj registered the highest temperature at 32.1 C, with Split Marjan and Rijeka also experiencing very high temperatures early in the day. The heat is expected to persist throughout the day, with meteorologists forecasting mostly sunny, very hot, and humid weather. Daytime highs are predicted to range between 34 and 39 degrees Celsius.

Red weather alerts for the severe heatwave remain in effect for the Osijek, Zagreb, Karlovac, Knin, Rijeka, Split, and Dubrovnik regions, while the Gospić region is under a yellow warning. Despite the predominantly sunny conditions, scattered showers and thunderstorms are possible in the afternoon in Gorski Kotar and inland Dalmatia, potentially accompanied by strong winds.

A more significant shift in weather is anticipated from Wednesday. Cooler air moving in from the north will bring clouds, rain, and thunderstorms, with the possibility of severe weather in some areas. This change will be accompanied by a noticeable drop in temperature as a northern wind and a bora wind strengthen. Meteorologists predict that the second half of Wednesday and Thursday will bring considerable relief with rain and thunderstorms, and potentially stormy weather at the beginning of the change. Afterward, more sunny periods are expected, but the weather will not be completely stable.
