Phuket and Andaman Sea forecast: what changed

Who this affects
Sea conditions matter most to passengers on ferries and speedboats crossing open water. Smaller, faster boats feel 1-metre waves more than larger vessels, so travellers prone to seasickness may prefer a bigger boat or an earlier departure. Tide times can also affect boarding at shallow piers.
Road transport is less exposed, though heavy rain can slow bus, minivan and private transfer journeys. If your trip combines a road leg with a boat leg, allow extra time between them.
Practical impact for your booking
On days marked caution advised, expect a bumpier ride and the possibility of operators adjusting or cancelling departures at short notice. Decisions are made locally by operators and harbour authorities on the day. Book connecting travel with a buffer, keep your ticket details and operator contact to hand, and check the conditions applied to your fare before travelling.
