Derawan Island Underwater Visibility: A Key Factor
When planning your diving trip, visibility is one of the most crucial factors to consider. In the dry season, visibility typically ranges from 20 to 30 meters (66 to 98 feet), allowing divers to fully appreciate the spectacular coral gardens and bustling marine life. In contrast, during the rainy season, visibility can diminish to 10-15 meters (33 to 49 feet) due to increased sediment in the water. Therefore, the best time to visit Derawan Island for optimal visibility is undoubtedly during the dry season.

Understanding sea conditions is essential for a safe and enjoyable diving experience. During the dry season, sea conditions are generally calm, with minimal waves and currents, making it easier for divers and boats to navigate. Expect surface temperatures around 28°C (82°F), creating a comfortable diving experience. However, the rainy season introduces rougher waters and stronger currents, particularly in December and January. Always consult the local weather forecast before diving and consider joining guided tours for more experienced navigation.
