Islands and the South
The South is Thailand's postcard factory — but it's really two coasts with opposite personalities and, crucially, opposite rain. Learn the two-coast logic and there's a good beach somewhere in Thailand every month of the year.
The two coasts
| Andaman (west) | Gulf (east) | |
|---|---|---|
| Marquee names | Phuket, Krabi, Phi Phi, Ko Lanta, Khao Lak | Ko Samui, Ko Phangan, Ko Tao |
| Look | Limestone karst drama, big-scenery bays | Coconut-island classic, gentler shores |
| Best window | Roughly November–April | Roughly January–August |
| Wet months | Roughly May–October | Peaks around October–December |
That offset is the two-coast trick: when one coast is monsoon-lashed, the other is often lovely.
Matching island to temperament
- Full-service and flights direct: Phuket — an island the size of Singapore with every Thailand on it (our sister site Phuket Addicts goes deep);
- Karst scenery per baht: Krabi province — Railay's cliffs, island-hopping day boats, Lanta's long ease;
- The Gulf trio: Samui (comfort), Phangan (moon parties and quiet yoga north — two islands in one), Tao (diving school of the world);
- The quiet names: Ko Yao pair, Ko Libong, Ko Sukorn, and the far-south Andaman gems — for those whose addiction has progressed;
- The deep south mainland (Trang, Satun): southern-Muslim food culture, karst without crowds, ferries to empty islands.
Southern food
The South eats loud: fierce yellow curries, turmeric fried chicken, roti culture from the Muslim south, seafood grilled metres from the boat. Follow morning markets and the food literacy rules — the region rewards them most.
