With over 260 days of sunshine a year, Lošinj belongs to the sunniest areas of Croatia.

One of the sunniest destinations in the Republic of Croatia with over 260 days of sunshine is Lošinj, an island in the northern Adriatic of controlled microclimate.


This is primarily influenced by the wind, solar radiation, humidity, and temperature that give an impression that you are in a lush winter garden, pleasant and revitalising, regardless of the season. The feeling of comfort changes throughout the year, but there are no major discrepancies from the average which ranks the climate on Lošinj from very cold to pleasantly warm.

During autumn and winter, mostly from mid-November through mid-March, the sensation is quite cold, and in the morning and the evening it is very cold. However, in early spring and early autumn the sensation of cold is gone, and the sensation of comfort prevails which attracts a greater number of visitors who are looking for an active holiday, hiking, or sports activities. Such visitors choose Lošinj as their destination for active holidays in April and May, and September and October.

In summer, mornings and evenings are pleasant so staying outdoors is possible throughout the day. An exception to this is the end of July and early August when afternoons are extremely warm, and the sensation of heat is easily alleviated by swimming in the beautiful, crystal clear sea in one of the island’s bays.

According to Köppen climate classification that classifies the climates by two elements – air temperature and precipitation, Lošinj belongs to a group of mildly warm climate. The warmest month is July with average temperature of 24.5 °C, while the coldest is February with average temperature of only 7.7 °C. From early June to the end of September average daily air temperatures are above 20 °C while the sea temperature is constantly suitable for swimming.

Cold days, when the air temperature drops below 0 °C are very rare. As a comparison, the  days when the temperature rises above 25 °C are quite numerous, and most of the days in July and August are such. Often the temperature rises above 30 °C which characterises them as extremely warm days. During that time the nights are warmer too, so it does occur that the night air temperature doesn’t drop below 20 °C.

As far as clouds are concerned, they occur more often in winter and it is possible that the half of the sky is overcast, but in spring the cloudiness decreases and it completely disappears in summer so the average annual levels are less than 5 tenths cloudiness.

From November to February there are 4 to 5 hours of sunshine a day, and during summer, the sunniest  season, the sun shines on average more than 10 hours a day.

There are more clear days when the average daily cloudiness is less than 2 tenths, and the greatest number of clear days occur in summer – in July and August those days take up more than one third of a month. The highest number of cloudy days occurs from November to March, however, even then there are no more than 10 cloudy days in a month.

Annually there is about 918 mm of rainfall in Mali Lošinj. The least precipitation occurs in summer, the most in autumn and winter. 59% of total precipitation occurs from October to March when there are on average less than 10 days of rainfall. In accordance with the characteristics of maritime precipitation regime, there is almost no rainfall in summer, with an average of 3 to 5 days of precipitation.

The winds are weak, mainly bora and the south wind, which is typical for the entire coast, and in the summer mass of air from the west is possible, known as mistral.
