When to Go for Diving and Snorkeling in Thailand
Thailand is a top destination for diving and snorkeling, offering great conditions year-round. However, the best time to visit depends on the region and weather. Thailand has two main areas for underwater activities: the Andaman Sea on the west coast and the Gulf of Thailand on the east coast. Knowing the best times for each region helps ensure calm waters, clear visibility, and a fantastic experience.
Always make sure your instructor is experienced and licensed. I recommend you to choose Travelfika to arrange snorkeling and diving as they have a lot of experience in this field
Andaman Sea Season: November to April
The Andaman Sea is on Thailand’s west coast and includes popular spots like the Similan Islands, Surin Islands, Richelieu Rock, and Phi Phi Islands. The best time to visit is November to April, when the weather is dry, and the sea is calm. During this period, the skies are clear, and the water visibility is excellent, often reaching up to 30 meters.
The peak time is from December to February, when conditions are ideal for spotting marine life like manta rays and whale sharks. November and April are also great months to visit, with fewer crowds and good weather. Many top snorkeling and diving areas, like the Similan Islands, are only open during this season to protect the marine environment.
From May to October, the Andaman Sea experiences the monsoon season. Heavy rains and rough seas make snorkeling and diving less enjoyable, and most operators stop running tours.
Gulf of Thailand Season: May to September
The Gulf of Thailand is on the east coast and includes places like Koh Tao, Koh Samui, and Koh Phangan. The best time to visit is May to September, when the weather is dry and the sea is calm. Visibility is excellent, making it easy to explore coral reefs and spot colorful fish.
Koh Tao is a favorite destination in this region, offering calm waters and affordable diving courses. While snorkeling and diving are available year-round in the Gulf of Thailand, it’s best to avoid the northeast monsoon season, which runs from October to January. During this time, the sea becomes rough, and visibility decreases.
Weather Tips and Planning
Thailand has a tropical climate, so temperatures stay warm throughout the year. However, monsoons affect sea conditions, so it’s important to plan your trip carefully.
- Pick the Right Season:
- Visit the Andaman Sea from November to April.
