Book Your Tour

When it comes to diving, timing can make a big difference. Koh Tao’s diving schools operate year-round, but the diving conditions vary with the seasons, so understanding the best times can enhance your underwater experience.

Seasonal Overview

• High Season (December to April): This is the most popular time for Koh Tao diving schools, thanks to clear skies, calm seas, and excellent underwater visibility. These months offer ideal conditions, with water visibility often reaching 20-30 meters, making it a prime period for courses and excursions.
• Shoulder Season (May to August): Fewer tourists mean smaller class sizes, often allowing for more personalized attention from instructors. While there’s a slight increase in rainfall, the diving remains fantastic, and you might even snag a discount from some Koh Tao diving schools.
• Monsoon Season (September to November): Rain and wind are more frequent, which can affect underwater visibility and dive schedules. However, some experienced divers enjoy the challenge, and Koh Tao diving schools remain open with flexible schedules for those willing to brave the conditions.

Marine Life by Season

The timing of your visit can also influence the type of marine life you’ll encounter. Whale sharks, the gentle giants of the sea, make seasonal appearances around Koh Tao, with sightings most likely from March to April and again in October. Diving schools keep track of these sightings, so if seeing a whale shark is on your list, ask about recent activity when you arrive.

Pro Tip 📝: If you’re set on specific marine encounters or prefer the clearest conditions, consult with Koh Tao diving schools before booking to find the best match for your goals.
