When To Go · Destination Guide
An Andaman basecamp for reefs, wrecks, and limestone island day trips
When to go
Phuket's planning is driven by sea state more than temperature.
Best overall window
Drier weather, calmer seas, and clearer water. Expect warm days and water often around 28°C.
Outside that window
Southwest monsoon with gustier winds (often 20 km/h to 35 km/h) and higher swell on exposed coasts.
Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
The overall row stays visible so you can compare it against the currently selected scope.
| Scope | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Overall | Overall - Jan: Best | Overall - Feb: Best | Overall - Mar: Best | Overall - Apr: Best | Overall - May: Good | Overall - Jun: Tradeoffs | Overall - Jul: Tradeoffs | Overall - Aug: Tradeoffs | Overall - Sep: Tradeoffs | Overall - Oct: Good | Overall - Nov: Best | Overall - Dec: Best |
These do not replace the overall planner. Use them only if a specific animal or event is driving your trip dates.
