The best time to visit Croatia’s islands is from Spring till Autumn. Water in April would have about 15 °C (60 °F) and air about 20 °C (70 °F) during the day. In July and August water temperatures can rise above 25 °C (77 °F) and air over 35 °C (95 °F)- which doesn’t feel that hot as there is always a light breeze at sea. In Autumn the air and sea temperatures remain pleasant until the end of October. Spring and Autumn are also more windy and suitable for downwinders and sailing, while summers are calmer.
