Water Temperature: The water temperature around Koh Tao is quite consistent, typically ranging between 27°C to 30°C (80°F to 86°F) throughout the year.

Visibility: Visibility can vary significantly depending on the season and weather conditions. From March to September, you can usually expect excellent visibility ranging from 10 to 30 meters (33 to 100 feet). However, during the monsoon season (October to December), visibility can drop to around 5 to 15 meters (16 to 50 feet) due to increased plankton blooms and runoff from rain.

Currents and Tides: Currents around Koh Tao are generally mild, making it ideal for novice divers. Most sites, especially those on the western side, experience minimal current. However, some sites like Chumphon Pinnacle can have stronger currents, which are more suitable for advanced divers. Tidal variations do affect the conditions slightly, with high tide often providing the best diving conditions.

Safety Tips:

  • Stay Hydrated: The tropical climate means you can dehydrate quickly. Always drink plenty of water before and after your dives.
  • Avoid Decompression Sickness: Ensure you follow your dive computer or dive tables strictly. Always perform a safety stop after each dive.
  • Beware of Boat Traffic: Koh Tao is a bustling dive destination with lots of boat traffic. Always use a surface marker buoy (SMB) when ascending.
  • Watch Out for Marine Life: Although encounters are generally safe, remember to respect marine life. Avoid touching or harassing sea creatures and be aware of your surroundings.

Regulations:

  • Marine Conservation Zones: Some areas around Koh Tao are designated as marine conservation zones. Dive operators will guide you on where these areas are and the restrictions that apply.
  • Restricted Gear: Spearfishing and the use of gloves are prohibited at many sites to protect the delicate reef structures and marine life.
  • Waste Disposal: It is illegal to dispose of any waste in the ocean. Ensure all trash is properly disposed of onshore.
  • Permits and Fees: Some dive sites may require permits or additional fees. These are typically handled by your dive operator.
