Best Times for Snorkeling
Seasonal Considerations
High Season (November-March): ✅ Best visibility (20-30 meters) ✅ Calm seas and minimal rain ✅ Optimal weather conditions ✅ Most tours operating
Low Season (May-October): ✅ Fewer tourists, more space ✅ Lower tour prices ❌ Reduced visibility during rains ❌ Some tours cancelled due to weather
Daily Timing
Morning (8am-11am): Calm waters, good visibility Midday (11am-2pm): Best lighting underwater Afternoon (2pm-5pm): Warmer water temperature
Tide Considerations
High tide: Deeper water, easier access to reefs Low tide: Better for tide pools and rock formations 2 hours before/after tide change: Often best conditions
Environmental Conservation
Protecting Coral Reefs
Use reef-safe sunscreen: Chemical sunscreens kill coral Don't stand on coral: Even dead coral is part of ecosystem Don't collect souvenirs: Shells and coral should stay Maintain proper distance: Don't kick or damage reef Report damage: Help conservation efforts
Responsible Wildlife Viewing
Don't chase animals: Let them approach naturally No flash photography: Can stress marine life Maintain distance: Especially from turtles and sharks No feeding: Disrupts natural feeding patterns Respect breeding areas: Some areas seasonal closures
Sustainable Tourism
