The weather in September
What the season does to Koh Lanta this month.
Worth knowing
Andaman Monsoon: Rough Seas and Red Flags
The south-west monsoon brings rain most afternoons and rough seas from May to October, worst in September. Red flags (no swimming) are common on Phuket's west-coast beaches, where rip currents drown swimmers every year; speedboat trips are cancelled at short notice and the crossings are bumpy. Hotels are much cheaper than in the high season.
What it costs
For two sharing a room; 3 days on the ground, getting there not included.

- Hotels are much cheaper than in the high season.
Totals cover the room (taxes included), food, local transport, entry and a 10% buffer: the figures the planner opens on. These are typical rates; Tourisma has no month-by-month rates for Thailand yet, so they don't move with the month.
