The best Months to dive in Rock Islands

The Rock Islands offer excellent diving conditions year-round. Water temperatures typically range from 27°C–30°C/81°F–86°F, making it comfortable for divers in every season. Visibility is usually outstanding, averaging 18–30 meters/59–98 feet, which allows for remarkable underwater experiences. Diving is possible throughout the year, but the dry season from November to April is particularly favorable due to calmer seas and minimal rainfall. Between June and August, stronger winds and currents can occur, occasionally reducing visibility and making some dive sites less accessible. However, these conditions vary, and many divers still enjoy exploring the vibrant marine life during these months.
