May weather forecast
Croatia

In May, Croatia fully steps into the spring season, displaying a significant shift towards warmer conditions and more sunshine. The landscapes burst into vibrant hues as the countrywide temperatures continue to rise.

The inland regions, encompassing cities like Zagreb and Čakovec, typically experience average temperatures ranging from 15°C (59°F) to 24°C (75.2°F). The sun shines for longer durations, bringing ample warmth and encouraging the bloom of diverse flora. The frequency of rainfall reduces, averaging between 30mm (1.18") to 50mm (1.97"), usually manifesting as short-lived spring showers.

In the mountainous areas of the Dinaric Alps, including the Velebit and Pljesevica ranges, the last traces of winter fully disappear. The temperatures in these areas average between 10°C (50°F) to 16°C (60.8°F), with the melting snow feeding into the country's rivers and lakes. These regions come alive with a wide variety of blooming plants and active wildlife.

The Adriatic coast, with its cities like Split, Dubrovnik, and the island of Hvar, presents an inviting climate in May. The coastal areas enjoy warmer average temperatures from 20°C (68°F) to 25°C (77°F). Rainfall is relatively scarce, with values typically between 20mm (0.79") and 40mm (1.57"). The extended daylight hours coupled with the Mediterranean warmth make this region increasingly attractive for early beachgoers.

The month of May sets the stage for the upcoming summer in Croatia, characterized by more consistent weather, fewer rain showers, and progressively warmer temperatures. It is a period where the days become longer, and the country starts gearing up for the peak tourist season.
