Best time to dive in Kornati Islands

Optimal Diving Seasons

Peak Seasons

The best time for diving in the Kornati Islands is during the summer months, particularly from June to August. During these months, the waters are warmest, typically ranging from 22°C to 26°C, making for comfortable and enjoyable diving experiences. Visibility is often at its peak, reaching up to 30 meters, which is perfect for appreciating the stunning underwater landscapes and diverse marine life. Additionally, the weather conditions are generally stable with calm seas, providing ideal conditions for both novice and experienced divers.

Off-Peak Seasons

Diving in the off-peak seasons, specifically during spring (April to May) and autumn (September to October), also has its advantages and disadvantages. Pros include fewer crowds, which means more serene and less crowded dive sites, and often lower prices for diving tours and accommodations. The water temperatures during these months range from 18°C to 21°C, which is cooler but still manageable with a proper wetsuit. However, divers should be prepared for the possibility of more variable weather conditions, including occasional rain and less predictable sea conditions. Despite these challenges, the off-peak seasons still offer a rewarding diving experience, with the chance to see unique marine life that may not be as prevalent during the peak summer months.

Month-by-Month Guide

January to March: Diving in the Kornati Islands during these months can be challenging due to colder water temperatures, often dropping to around 14-16°C (57-61°F). Visibility is generally good, but marine life activity is lower, and weather conditions can be unpredictable with frequent storms.

April to June: These months mark the beginning of the diving season. The water temperature gradually warms up to around 18-22°C (64-72°F), and the marine life becomes more active. May and June are considered excellent months for diving as visibility is at its peak, often exceeding 20 meters (65 feet), and the water is calm.

July to September: This is considered the peak diving season in the Kornati Islands. Water temperatures range between 24-27°C (75-81°F), providing comfortable diving conditions. Marine life is abundant, and visibility remains excellent. However, dive sites can become crowded, especially in August.

October to December: As autumn sets in, water temperatures begin to drop, ranging between 18-20°C (64-68°F). Marine life is still active, but visibility can start to decrease due to increased plankton. Despite the cooling temperatures, October can still offer good diving conditions, but November and December are less predictable due to weather changes.
