Phuket's Climate
Phuket sits on Thailand's Andaman (west) coast, giving it a genuinely distinct monsoon pattern from Gulf coast islands like Koh Samui. Temperatures stay fairly consistent year-round (26-32°C); what changes is rainfall and sea conditions, driven by the Southwest monsoon.
DRY SEASON
November – April
Best overall visiting window
- Lowest rainfall, calmest seas of the year
- All island tours (Phi Phi, Similans, James Bond Island) running
- Peak crowds and prices in December-January
SOUTHWEST MONSOON
May – October
Rain, rougher seas, lower prices
- Short, sudden downpours are common, not all-day washouts
- Similan Islands National Park closes entirely (see below)
- Some boat tours may be cancelled on rough-sea days
HOT SEASON OVERLAP
March – April
Hottest, driest stretch, Songkran festival
- Highest daytime temperatures of the year
- Still within dry season — sea conditions remain calm
- Songkran (Thai New Year) falls mid-April
ℹ️ Good to know: Phuket's monsoon (roughly May-October) runs opposite to Gulf coast islands like Koh Samui, which see their wettest months around October-December. If Phuket is having a rainy week, the Gulf coast may still be dry — worth knowing if your trip includes both coasts.

💡 Pro tip: November and February give you the driest, most comfortable window with reasonable prices — the sweet spot for most Indian travellers wanting reliable island-tour weather without December-January peak pricing.

Similan Islands Seasonal Closure
MAY 16 – OCT 15 (TYPICAL)
The Similan Islands National Park — widely considered Thailand's best diving and snorkelling destination — is officially closed to visitors every year during the monsoon, typically from mid-May to mid-October, for environmental conservation and diver safety in rough seas.
🤿 If diving the Similans is a priority: Book your Phuket trip for November through April specifically. There is no workaround for the closure — no operator runs trips to the Similans during the official closed season, regardless of budget.
ℹ️ Alternatives during monsoon season: Phi Phi Islands and James Bond Island tours generally continue to run year-round, though may be cancelled on specific rough-sea days during peak monsoon months (June-September).
💦
Songkran Festival Timing
MID-APRIL
Songkran, the Thai New Year water festival, falls around April 13-15 each year and turns Phuket's streets — especially Patong — into a city-wide water fight. It's a genuinely fun, high-energy time to visit, but comes with real practical trade-offs.
💦 What to expect: Expect to get soaked simply walking down the street, expect crowds and higher prices, and expect some regular sightseeing to take a backseat to the festival atmosphere for a few days. It coincides with Phuket's hottest month, so the water fights are also a genuinely welcome relief from the heat.
💰
Cost Levels by Month
Flight and hotel prices to Phuket move with the dry/monsoon season and major holiday periods — December-January and Songkran (April) stand out as the priciest windows.

Frequently Asked Questions
When is the Similan Islands closed?
The Similan Islands National Park is officially closed each year from around mid-May to mid-October for environmental conservation during the monsoon season. Plan any Similan diving or snorkelling trip for November through April.
Does Phuket have the same monsoon season as the rest of Thailand?
Phuket sits on Thailand's Andaman (west) coast, so its monsoon season (roughly May-October) is opposite to Gulf coast islands like Koh Samui, which see their wettest months around October-December. If Phuket is rainy, Koh Samui may still be dry, and vice versa.
What is the best month to visit Phuket?
November and February offer the best combination of dry weather, calm seas, and moderate prices — both fall within the dry season but outside the December-January peak crowds and pricing.
Is it worth visiting Phuket during monsoon season?
Yes, for budget travellers who don't need the Similan Islands specifically. Phuket's rain typically falls as short, intense downpours rather than all-day washouts, and Phi Phi/James Bond Island tours generally still run, just with occasional cancellations on rough-sea days.
When is Songkran in Phuket?
Songkran, the Thai New Year water festival, falls around April 13-15 each year. Patong becomes a city-wide water fight — expect crowds, higher prices, and to get soaked simply walking down the street.
What's the cheapest time to visit Phuket from India?
September typically has the lowest flight and hotel prices, falling at the peak of the monsoon. May and October are close runners-up, offering lower prices with somewhat better weather than the September trough.
