Know before you go
Short, straight answers to the questions every Koh Samui visitor asks before booking.
The sweet-spot months
December to April brings warm, dry, sunny weather ideal for the beaches, islands and boat trips — the prime time to visit Koh Samui.
Dry & sunny (Dec–Apr)
Warm and dry with calm seas, perfect for Ang Thong, snorkelling and the beaches; the best and busiest season.
Mid-year (Jun–Sep)
Relatively dry and pleasant when much of Thailand is wet — a good shoulder window with fewer crowds.
Rainy (Oct–Nov)
Samui’s wettest months, with heavier rain and rougher seas; boat trips may be cancelled, but it’s green and quiet.
Best for boat trips
The December–April dry season has the calmest seas and clearest water for Ang Thong and snorkelling.
Full Moon Party
Nearby Koh Phangan’s monthly Full Moon Party draws crowds — fun but book accommodation and boats ahead.
One day
An island tour with the Big Buddha and a cruise.
Two days
Add the Ang Thong Marine Park.
Three days
The sweet spot: Ang Thong, the island, and Koh Tao or Phangan.
Four to five days
Add more snorkelling, jungle safaris and beach time.
A week or more
Combine Samui with Koh Tao and Koh Phangan.
Travelling with kids
Mix Pig Island, elephants and calm beaches.
Songthaews
Shared songthaew pickups run set routes around the island for a low fare — the cheap local way to get around.
Taxis & ride apps
Taxis and Grab operate on Samui; agree fares or use the app, as metered taxis are rare.
Tour transfers
Most island, Ang Thong and elephant tours include hotel pickup.
Scooter & car hire
Scooters and cars are popular for exploring; ride carefully, as roads can be hilly and busy.
Boats to the islands
Speedboats and ferries from Samui reach Ang Thong, Koh Tao, Koh Nang Yuan and Koh Phangan.
From the airport
Koh Samui Airport (USM) is central, about 10–20 minutes from most beaches by taxi or transfer.
Thai baht
Thailand uses the baht; cards work in hotels and resorts, but carry cash for markets, songthaews, boats and street food.
Pick calm-sea days
For Ang Thong and snorkelling, the December–April dry season has the calmest, clearest water.
Choose ethical elephants
Pick no-riding, welfare-focused sanctuaries that let elephants roam freely.
Respect temples
At the Big Buddha and temples, dress modestly — cover shoulders and knees — and remove shoes where required.
Sun protection
The tropical sun is strong on boats and beaches; bring reef-safe sunscreen, a hat and water.
