Let’s start with the main thing – it’s always summer in Phuket, hooray! The island is located just 872 km north of the equator, so the warmth never really leaves here. However, there is still some seasonality, and the relaxed heat gives way to rains.
Phuket is like a woman with a changeable mood. During this period, the island is affected by the monsoons, so rain is a frequent guest. But this does not mean you’ll be swimming through the streets instead of the sea. Most often, there are heavy but short-lived downpours, and many days still bring sunshine and temperatures around +32°C.
The sea during this period can be rough, and it is very important to pay attention to warning signs in the form of red flags on the beach (we’ve described all possible flags in more detail in this article). If you see such flags, it’s better not to play the hero.
The situation at most beaches requires vigilance – we recommend checking the “Waves” section in the above-mentioned Windy app before heading to the beach. If you’re unlucky with the weather and the waves are really big, there is always a solution in Phuket – go to the “Beaches without waves in the low season” section. There we’ve collected beaches where, from May to October, there are typically no waves at all.
We recommend reading our article “Things to do in Phuket in bad weather – 8 ideas”.
The low season has not only downsides but also significant advantages, which is why we love this period no less than the high season:
Not just a season, but pure bliss! In November, rainfall decreases, the skies clear up, and the sea becomes calm and pleasant. Occasional night showers are possible, but overall it’s a true idyll.
From December to February, a paradise for sun lovers begins: the air warms up to around +35°C, and the water is warm and crystal clear, like glass. It’s the perfect time for swimming and exploring Phuket and its surroundings on excursions.
During this time, the heat reaches its peak and rainfall is minimal. The sea is calm, there is plenty of sunshine (perhaps even too much), and it is definitely not the time to neglect a hat and SPF.
On the plus side: prices are already starting to drop, while the rains have not yet begun.
We’ve put together a brief month-by-month summary in the form of a table:
| Month | Temperature | Sea & waves | Precipitation |
| January | +24–26°C at night, +30–32°C during the day | Calm sea, clear water | Occasional rain, mostly at night |

| November | At the beginning of the month: +25°C at night to +32°C during the day; it gets hotter mid-month | Sea becomes calm, swimming is possible on beaches | Short rain showers at the start of the month; more sunny days in the second half |
| December | +24–26°C at night, +29–32°C during the day | Clear and calm sea with no waves | Occasional night rain, about 8 rainy days per month; daytime is sunny or partly cloudy |
Just a reminder. Questions like “What’s the temperature right now?”, “Is it raining?”, and “Will I get blown away by the wind?” are most accurately answered by the Windy app. This is exactly what we recommend for up-to-date weather forecasts in Phuket. Important: only look at the next 5–7 days, as forecast accuracy decreases significantly beyond that range.
