Seasons in Ko Samui & the Gulf coast
The rain runs September to January
Which part of the country
It is rainy season in Ko Samui & the Gulf coast right now, and it runs September to January. The rain tends to come hard and short rather than all day, and it stays warm through it — so the thing to bring is a shell you can fold into a day bag, not a coat.
Going in April
The dry half of the year, and exactly when the west coast is wet — which is the whole reason to know these two coasts apart.
What this means for your bag
Real sun protection
High-factor sunscreen, a hat with a brim and sunglasses. Reef-safe sunscreen is worth buying before you go — it is expensive and hard to find at the beach.

Cotton takes two days to dry in this air and starts to smell before it does. Synthetics and merino wash in a sink and are wearable by morning.

Everything stays slightly damp. Pack fewer clothes and plan to wash them, and keep anything that must stay dry in a sealed bag.

Heat like this needs far more water than you think. A filter bottle also spares you buying a plastic bottle every two hours.
