Check Monsoon Windows

Andaman coast beaches (Phuket, Krabi) have rough seas May–October. Koh Samui's beaches are roughest October–December, and Hua Hin's wettest months are September and October. Plan your beach trip around these windows for calm water and safe swimming.

Why go, and how to do it well

Situated off the coast of Rayong in the Gulf of Thailand, Koh Samet is a popular island destination known for its relatively accessible location — roughly 200 kilometers from Bangkok — making it a favored weekend retreat for both locals and international travelers. The island sits within a national park, which has helped preserve much of its natural shoreline, and the beaches here are characterized by fine white sand and calm, clear waters suited to swimming and relaxing.

Visitors can expect a range of atmospheres depending on which stretch of beach they choose. The main beach areas, particularly along the eastern coast, offer a mix of beachside bars, seafood restaurants, and sun loungers, while quieter coves further south provide a more secluded experience. Water activities such as snorkeling and kayaking are readily available, and the island's compact size makes it easy to explore multiple spots in a single visit.

Tips for Visiting Beaches

Go Early for Empty Sand

Even the busiest beaches are nearly deserted before 9 AM. A sunrise walk is the best hour of the day on the sand, and you'll beat the heat for a morning swim.

Use Reef-Safe Sunscreen

Many Thai marine parks ban chemical sunscreens that damage coral. Bring reef-safe (mineral/zinc-based) sunscreen from home — it's harder to find and pricier in Thailand.
