Beach seasons in Koh Samui

High Season: The dry season is the busiest time of the year to enjoy the beach in Koh Samui. Not too hot and dry. High season goes from mid January to March.

Hot Season: Comprises from Apr to July. During this time beaches in Koh Samui are the perfect heat cure, in combinations with the occasional thunderstorm.

During the monsoon: During October and November rain is intense in Koh Samui and not the best time to visit the island if your main motivation is to spend time sunbathing at the beach.

Floods: If you experience floods in Thailand during the monsoon, please try not to touch or submerge in standing water. It can be quite dangerous, there maybe sharp objects and currents and the water may carry bacteria that may get you in trouble. Wait until it pass! Allow some time for the ocean to clear the waters from floods before going for a swim.

Things to keep in mind

Sun in Thailand: Sun beams in Thailand does not forgive! Make sure you are protected against sunburns with adequate sun protection factor cream. Take special care with small children and babies.

You got sunburns in Thailand?. Ouch, it hurts… Nothing better than a special massage to hydrate your skin. In many Thai beaches you will find covered beds where you can get a coconut massage treatment on your skin to treat sunburns right on the sand

Box jellyfish in Koh Samui: Chances to be stung by a box jellyfish in Koh Samui are low, but better be prepared than unaware. During August, September and October box jellyfish is more noticeable in the Gulf of Thailand. Certain species of box jellyfish carry a extremely venomous toxin, so make sure to keep reading to understand what to do if you get stung.

If you get stung: Right after being stung by a box jellyfish, apply vinegar directly on the area affected for at least 30 to 60 seconds. Go immediately to a hospital. Most boats, resorts, beach restaurants and bars in Koh Samui should have vinegar on their first aid kits to treat stings. Do not try to clean the injury with fresh water. Do not pee on the area affected!!

Public space and beaches in Thailand: You may see banners entering a beach reading “private beach” or “only customers”. You can ignore all those banners because all beaches in Thailand are public.

Chaweng Beach with fine white sand and turquoise water is one of the most popular beaches on the island. Chaweng area is the most developed and touristy area in Koh Samui, with plenty of resorts, restaurants bars, shops, food stands. Night life in Koh Samui is vibrant, specially in Chaweng area. Having everything within minutes is great, but you may have to trade convenience for quietness during the high season.

White powdery sand |Crystal clear water | Nightlife | Convenience: Everything you may need at walking distance | Plenty of beach and water activitie | Plenty of choice: hotels, restaurants, bars, shopping...

  • TIPS

We love the laid back vibes in Lamai! Lamai beach can get busy, especially during the high season, but nothing close to Chaweng beach. Lamai is the second longest beach in Koh Samui. There are many options for dining and shopping in Lamai, not as sophisticated as Chaweng or Bohput, but prices are better. Surrounded by tropical hills and less developed than other popular locations in Samui, Lamai is perhaps a little bit more "authentic"...

A beach for everyone | Swimmers (South)

White sand | Clear water | Many restaurants and bars around | Many shopping options | Lamai Night Market | Affordable area (compared to Chaweng or Bohput)

Few girl bars around | Not as busy as Chaweng but still busy | Some spots North of the beach quite rocky

Sunday is the day to visit Lamai! Spend a day at the beach and stay later to visit Lama Night Market

Bohput Beach spreads along Fisherman's Village walking street, packed with great restaurants and bars. The beach it is beautiful, with nice views and stunning sunsets looking over Koh Phangan. What makes Bohput Beach and the area especial is the relaxed atmosphere less "in your face" than Chaweng. Terraces with amazing views, no traffic, quality spas and exclusive shops make Bohput  one of the best beaches in Koh Samui to spend the day.

Families | Senior visitors | Couples

Chilled atmosphere | Beach spreading along Fisherman's Village | The Wharf mall | Great options for eating out some on the beach | Nice bars and cocktails | Walking street

Bophut tends to be more expensive than other areas like Lamai | Busy during the high season | Sand is coarse | Many boats in the water
