Beaches and islands

Where to swim, when the sea behaves, and which coast suits the month you are able to travel. The month decides more than the reputation of the beach does.

Two coasts, two calendars

The coasts here run on opposite calendars. Thailand's Andaman side, meaning Phuket and Krabi, is at its best from November into April and wet and choppy from May through October. The Gulf coast around Koh Samui reverses that, with its worst weather in November. Vietnam adds a third pattern: Da Nang and Hoi An are dependable from February to August, while Phu Quoc is dry roughly when the Andaman is. The wrong coast for your month is the commonest way a beach week goes wrong.

The second thing worth saying out loud is the crowding. The water around Koh Phi Phi takes hundreds of boats a day, and arriving at eleven in the morning is an exercise in queueing. We work around it: departures at first light, anchorages on the far side of the same island, and beach nights at the end of a route, once you have stopped wanting to look at things. We name the bay and the sort of hotel; the property and the price come in writing.

What these trips look like

  • The coast picked by month rather than by name: Andaman, Gulf, central Vietnam or Phu Quoc, whichever is dry then.
  • Beach nights at the end of the route, after the temples and the driving, not stranded in the middle of it.
  • Private boat departures early enough to reach the good bays before the fleet arrives from the main pier.
  • Snorkelling stops chosen for water clarity in your month, with the reefs we would skip named as such.
  • Three nights minimum on any island, because two nights is mostly ferries and packing.
  • A warning when a crossing will be rough, and a flight offered in place of a boat where one exists.

Frequently asked questions

Which month is best for a beach week in Thailand?
For the Andaman coast, December to March gives the calmest water and the most reliable sun, with November and April close behind. If you can only travel between June and September, move to the Gulf side instead, where Koh Samui sits in the lee of the same system. Nowhere is guaranteed dry, but the right coast removes most of the risk.
Is Koh Phi Phi worth a night, or only a day trip?
It is worth a night if you plan around the traffic. The boats arrive from Phuket mid-morning and leave in the late afternoon, so the island belongs to whoever slept on it. Stay two nights, swim before eight, and go to the far bays while the day fleet is anchored elsewhere. If your week is short, a very early day trip is the sensible version.
Can we swim in both Vietnam and Thailand on one trip?
Sometimes, and it depends entirely on the month. February to April works for both, since the Andaman is still dry and the central Vietnamese coast has settled. From September to November the two are badly out of step and you would do better to pick one. We would rather put every beach night in the country that is dry.
