FAQ

Best time to visit Phuket: questions

For sunshine and calm seas, January to March. February is usually the driest month. December is also lovely but the busiest and most expensive.

Roughly May to October, when the south-west monsoon brings heavy showers. September is usually the wettest month.

In the green season, especially September and October. Prices are highest from mid-December to February.

Yes, with care. Showers are heavy but short – slow down, keep your distance, avoid flooded roads and wait out the worst downpours.

As early as possible – ideally two to three months ahead. Cars sell out and prices rise sharply from mid-December to early January and around Chinese New Year.

November is the shoulder month: rain eases off, seas calm down and prices are still below peak season – a good time for a road trip.

April is one of the hottest months, with daytime highs around 34°C. It is also Songkran – fun, but roads are slow and wet during the water festival.
