When Is the Best Time to Snorkel in the Kornati Islands?
The best time to visit the Kornati Islands for snorkelling
The best time to visit the Kornati Islands for snorkelling is during the summer months, from June to September. During this time, the water temperatures are warm and comfortable, ranging from 20°C to 26°C (68°F to 79°F). The visibility is also at its best, with underwater visibility often exceeding 30 meters (98 feet). The summer also offers calm seas, making it ideal for snorkelling and other water activities. The Kornati Islands receive a steady breeze, known as the Maestral, which keeps the air temperature pleasant and provides a refreshing respite from the summer heat. The Kornati Islands tend to get overcrowded during the peak summer, particularly in July and August. If you prefer a quieter and more peaceful snorkelling experience, consider visiting in June or September when the tourist crowds are thinner. The Adriatic Sea can experience sudden changes in weather, so it's advisable to check the weather forecast and sea conditions before heading out. Avoid snorkelling during strong winds or thunderstorms, as these conditions can make the waters unsafe.
⚠️ Reminder: Check official marine forecasts before your trip, and avoid snorkelling during strong Maestral winds or storms.
