Thailand in November: the verdict, region by region.

It sends November beach nights to the dry Andaman side rather than the Gulf's monsoon, and if your exact dates touch Loy Krathong it says so on the day.

November weather, coast by coast

Andaman coast — the grand reopening

The southwest monsoon that soaked Phuket, Krabi and Koh Lanta all summer wraps up around late October, and November is the coast waking back up: seas calm, longtail and speedboat routes resume in full, and the season's first stretches of blue-sky weeks arrive. Early November can still throw leftover showers — that's the honest caveat — but conditions improve week by week, and the payoff for going early is real: the same beaches that will be elbow-to-elbow in January are half-empty in mid-November, at shoulder-season prices. This is also the month Koh Lipe properly reopens, as the high-season boats from Pak Bara and Lanta restart.

Gulf islands: the one warning

Here's the fact almost every "Thailand in November" article buries: November is the wettest month of the year on Koh Samui, Koh Phangan and Koh Tao. The northeast monsoon peaks on this coast now — think multi-day downpours, churned-up seas, and the occasional cancelled ferry. Can you get lucky? Sure. Should you plan a beach holiday around getting lucky? No. If the Gulf islands are non-negotiable, go in late December or later, when the coast dries out.

The North — arguably its best month

The rains have ended, the countryside is still green from them, daytime temperatures ease into the high 20s with genuinely cool evenings, and the smoke of burning season is months away. Chiang Mai, Pai and Chiang Rai are all at their peak. And then there's the festival.

Loy Krathong and Yi Peng: the November full moon

On the full moon of the twelfth Thai lunar month — mid-to-late November most years, late November in 2026 — Thailand floats candlelit krathong baskets onto its rivers, and Chiang Mai adds Yi Peng: thousands of paper lanterns rising over the old city at once. It is, without exaggeration, one of the great sights in Asia, and it's worth planning a whole trip around. Two practical notes: Chiang Mai rooms for that week sell out well ahead (book the moment your dates firm up), and the big ticketed mass-release events outside town are optional — the free spectacle along the Ping River and around Tha Phae Gate is the real thing.

Where to go in November

Krabi and Railay — the karst coastline in its first dry weeks, before peak crowds. Koh Lanta — the mellow island at its shoulder-season best; a two-hour ferry from Krabi, bookable on 12Go (partner link). Koh Lipe — Thailand's far-south stunner, freshly reopened and quietest right now. Chiang Mai — for the festival and the season. Bangkok — the sweat finally breaks; riverside evenings turn pleasant.

Where we'd skip in November

The Gulf islands, as above — it's their monsoon, and no amount of Instagram optimism changes the rain radar. We'd also hold off on Phuket's big-resort strips until you've considered Krabi or Lanta instead: same coast, same weather, fraction of the concrete. If a Full Moon Party is your goal, note the November edition collides with the Gulf's peak rain — the December and January parties are the better bets.

Crowds, prices, and when to book

November is the last month of shoulder pricing on the Andaman side. Hotels step their rates up toward the December 20 – January 5 festive peak, so the early-November traveler gets high-season weather at pre-high-season prices — the best value-per-sunny-day of the whole season. Book beach hotels 4–8 weeks out, Chiang Mai for Loy Krathong week as early as you can, and domestic flights a few weeks ahead before festive fares kick in. One thing to leave off the early list on purpose: the Thailand Digital Arrival Card can only be filed in the 3 days before you land — free, five minutes, official site only.

A sample November itinerary

Our 14-night route in its Andaman version, timed for the month: three nights Bangkok → sleeper train north → three nights Chiang Mai (around the full moon if you can) → fly to Krabi → three nights Railay/Ao Nang → ferry to three nights on Koh Lanta → buffer night in Bangkok → home. If your dates hit Loy Krathong, anchor the whole plan on Chiang Mai and build outward.
