DHMZ data reveals extreme heat and varied rainfall marked Croatia's June

Croatia experienced a notably warm June in 2026, with temperatures consistently exceeding the 1991-2020 average across the country. The Croatian Meteorological and Hydrological Service (DHMZ) reported that deviations in average monthly temperatures ranged from 1.7 degrees Celsius in Daruvar and Makarska to an extreme 3.5 degrees Celsius at Zavižan.

This heatwave was particularly intense in mountainous regions and along the northern Adriatic coast, with areas like Puntijarka experiencing "extremely warm" conditions. Many parts of continental Croatia and the southern coast also recorded "very warm" temperatures. The data indicates a significant departure from typical June weather patterns.

Rainfall patterns presented a stark contrast. While Bjelovar and Varaždin saw exceptionally high precipitation, with Varaždin recording 169.4 millimeters (188.9% above average), other areas experienced severe dryness. Ogulin, for instance, had a "very dry" June, and eastern parts of the country, like Gradište and Slavonski Brod, also reported dry conditions. Mali Lošinj recorded a mere 1.5 millimeters of rain, just 2.7% of its average.

The DHMZ data underscores a trend of increasingly extreme weather events impacting Croatia, with both heat and precipitation extremes becoming more common. These fluctuations highlight the challenges of adapting to a changing climate.
