The Andaman Opens Its Doors Again: Andaman Coast Season 2026

When the monsoon swell finally subsides, the Andaman Sea turns the striking color of sea glass, and Thailand's west coast springs back to life. This October, the new season has officially kicked off. The Similan Islands in Phang Nga reopened on October 15, 2026, following a five-month monsoon closure, welcoming more than 1,300 visitors on opening day to marvel at the granite boulders and pristine white-sand beaches. Meanwhile, Maya Bay on Ko Phi Phi Le welcomed travelers back starting October 1, with the proper dry season expected to settle in by December.

Before booking any trips, one crucial change is worth noting: six marine national parks, including Similan, Surin, Phi Phi, Phang Nga Bay, and Ko Lanta, have adopted electronic ticketing since October 2025. Travelers are advised to purchase tickets in advance and keep their passports ready for inspection.

While numerous Thai beaches are lovely, certain unique experiences belong exclusively to this coastline:

• Meet the Moken at Mu Ko Surin: Situated far north near the Myanmar border, the Surin Islands host the Moken sea nomads, offering small-scale, community-led visits to learn about their maritime lifestyle.
• Dive the Similan and Richelieu Rock circuit: Home to Thailand's premier dive sites featuring boulder reefs and deep pinnacles, best explored via live-aboard trips from Khao Lak during peak visibility months.
• Look for dugongs off Trang: The seagrass beds around Ko Libong shelter endangered, peaceful dugongs in shallow protected coastal habitats where quiet boat trips with local guides offer a chance at sightings.
• Explore a UNESCO geopark in Satun: Thailand's southernmost Andaman province features the Satun Geopark with ancient fossils, sea caves, and the Tarutao archipelago, offering a much quieter alternative to Phuket.

Travelers planning to explore multiple provinces without rushing should allocate about ten to twelve days. Since October and early November can still bring rainfall and occasional boat cancellations due to high waves, building a spare day into the itinerary is strongly recommended. Ferry tickets and island accommodations should be booked early for December and January visits, while shoulder weeks offer the quietest travel experience.
