Koh Taen

Koh Taen (also known as Koh Tan) is a small, quiet island located just off the southern coast of Koh Samui. It’s best known for its calm atmosphere, shallow waters, and natural surroundings.

Unlike more developed island destinations, Koh Taen remains largely untouched. There are no large resorts or busy beaches, which makes it appealing for visitors looking for a slower, more relaxed island experience.

Most visitors explore Koh Taen as part of a short boat trip from Koh Samui, often combined with nearby islands such as Koh Madsum (Pig Island). The focus here is simple: swimming, light snorkeling, and enjoying a quieter side of the region.

Understanding Koh Taen’s weather helps ensure a comfortable trip, especially since most visits involve short boat rides and time in the water.

Climate Overview

Koh Taen has a tropical climate with warm temperatures year-round, typically ranging between 26–32°C (79–90°F).

Best Time to Visit

Calm sea conditions generally offer the best experience, with easier boat crossings and clearer water for swimming and snorkeling. Lighter wind days are ideal.

Rainy Season

During the monsoon months, sea conditions can become less predictable. Trips may still operate when weather allows, but schedules can change depending on wind and waves.

Timing & Conditions

Trips usually depart from the south of Koh Samui and involve a short crossing. Morning departures often provide calmer sea conditions.

What to Bring

Bring reef-safe sunscreen, swimwear, a towel, and sun protection. Water shoes can be helpful when entering or exiting the sea.

Expectations

Koh Taen is a quiet, nature-focused stop. There are limited facilities, so it’s best approached as a relaxed island visit rather than a full-day destination.

Island Combinations

Koh Taen is commonly combined with Pig Island, offering a mix of calm nature and a more playful stop in one trip.
