Best months to visit
MarchApril
December to February is the prime Phi Phi window — calm sea, low rain, full operations and crystal water. November and March are excellent quieter shoulder months. April is hot before monsoon. May-October is wet and many small resorts close; underwater visibility drops, offshore swimming risky. Maya Bay seasonal closure (typically Aug-mid-Oct) is the major scheduling constraint.
Best for
Beach
November-April — Tonsai, Long Beach and the Maya Bay (when open) at their calmest and clearest. Sea 29-31 °C; full beach service.
Hiking
December-February — Phi Phi Viewpoint hike is coolest and driest then; midsummer (April-May) heat is intense on the exposed limestone path.
Sightseeing
November-April — Maya Bay, snorkel sites at Bamboo Island and Pi Leh Lagoon are most reliable for tour operations; underwater visibility best.
Climate notes
- Southwest monsoon wet season (May-October): humid air from the Indian Ocean brings 200-290 mm of rain per month. September-October is the wettest with frequent strong winds; many smaller resorts close.
- Northeast monsoon dry season (November-April): drier air from the Asian mainland; rainfall drops to 20-70 mm/month, January-February averages just 6 rainy days.
- Tonsai Bay sheltered by limestone cliffs: the famous bay between Koh Phi Phi Don's two halves is partially protected — sea is calmer here than the open Andaman in shoulder seasons.
- Maya Bay (Phi Phi Leh): closed seasonally for reef recovery — typically open mid-October through July, closed August-mid-October. Check the latest schedule before visiting.
- Tropical thunderstorms: short, intense afternoon downpours in shoulder seasons (April, October-November); mornings often clear, even in wet season.
- Cyclone-free direct: at 7-8°N Phi Phi sits below typical cyclone tracks; tropical depressions occasionally cross from the Bay of Bengal but direct hits are rare.

Regional notes
- Tonsai Bay (Koh Phi Phi Don's main strip): partly sheltered by limestone cliffs; central nightlife and ferry pier. Calm enough for swimming year-round but underwater visibility drops in wet season.
- Long Beach (Phi Phi Don, southern stretch): quieter, longer beach with reef snorkelling just offshore.
- Maya Bay (Phi Phi Leh): the iconic 'The Beach' bay — closed August through mid-October for environmental recovery, with day-trip-only access (no overnight). Visitor numbers and schedule subject to change.
- Pi Leh Lagoon (Phi Phi Leh): calm jade-green inlet popular for snorkelling and kayaking; often included in day-tour itineraries.
- Bamboo Island and Mosquito Island (north): white-sand snorkel stops; access often skipped in rough weather.
Frequently asked questions
When is the best time to visit Koh Phi Phi?
December to February — calm Andaman sea, minimal rain, all snorkel and dive sites operational. November and March are also excellent with similar weather and fewer crowds. December-January peaks for prices and crowds.
Is Maya Bay open year-round?
No — Maya Bay typically closes from August through mid-October for environmental recovery and reopens late October. Day trips only (no overnight stays). Visitor numbers are capped and operating hours can change. Always check the latest National Park notice before booking.
Can I visit Koh Phi Phi in the rainy season?
Yes — half-price accommodation, lush greenery, but rough seas, occasional ferry cancellations, frequent storms, and many small resorts and dive operators close. May-July is the best wet-season window (less violent than September-October).
Andaman vs Gulf of Thailand — what is the difference for Phi Phi?
Phi Phi is on the Andaman side, so wet season is May-October, dry is November-April. The Gulf side (Koh Samui, Koh Tao) has the opposite pattern — wet October-December. If you want sun in November, both sides usually deliver. October is the worst month for Phi Phi.
How is the diving at Phi Phi?
Year-round, but visibility peaks November-April (often 25-30 m). Wet season visibility drops to 10-15 m and currents stronger; many dive operators reduce schedules. Hin Daeng/Hin Muang reefs to the south are best in dry season for the best chance of mantas and whale sharks.
When are crowds lowest at Maya Bay?
Mid-week mornings on opening day after annual reopening (late October), and any day before 9 am or after 4 pm in dry season. The Park caps daily visitors but tour boats still arrive in waves.
What is the water temperature at Phi Phi in January?
About 29 °C — extremely warm by any standard. Most divers and snorkellers do not need a wetsuit; a rash vest is enough for sun protection.
Are there cyclones at Phi Phi?
No direct cyclones — Phi Phi at 7-8°N is below the usual cyclone formation belt. Tropical depressions cross from the Bay of Bengal occasionally and bring heavy rain plus rough seas, but classic typhoons or cyclones do not strike directly.
