🤿 Diving & Snorkeling
October to March provides the best underwater visibility (30-50m). The southeast monsoon (Kusi) from June-September can bring stronger currents but also nutrient-rich waters attracting larger marine life.
🦈 Whale Shark Encounters
September to March is whale shark season, particularly around Mafia Island. October and November offer the highest sighting probability.
🐢 Turtle Watching
