Derawan Islands in January
Not the best time
January is honestly tough on the Derawans. The constant rain and rough seas mean limited diving and frequent trip cancellations. Save your money for a better month.
Weather
January brings the peak of the wet season with heavy rainfall and choppy seas. Humidity stays around 85% with frequent afternoon thunderstorms that can last for hours. The seas are rough, making boat transfers to the islands challenging and sometimes dangerous.

All Months
April through September offers the calmest seas and clearest visibility for diving. Visibility regularly exceeds 30 meters during these months, and boat rides between islands are comfortable. This is peak season, so book accommodations well in advance.
Manta ray sightings peak from May to August when plankton blooms attract them to cleaning stations. Whale sharks are present year-round but seem more active during the calmer months.
Avoid October through March when northeast monsoons bring rough seas and frequent rain. Many dive operators close during January and February due to dangerous conditions. Even if you can get there, you'll spend most days stuck indoors.
The shoulder months of April and September offer the best value with good weather but fewer crowds. Water temperature stays around 28°C year-round, so a 3mm wetsuit is plenty.
