▷ Phuket Weather Month by Month ☀️ 🌤️ 🌦️ 🌧️ 🌩️

Which is the best month to visit Phuket?

What will Phuket weather be on the month I arrive? What is the best month to visit Phuket? These are questions we get very often, and some tough ones to answer, and this for a couple of reasons. First, even though there is some expected high and low seasons, there are no guaranteed patterns. Each year, the weather in Phuket is unpredictable, and each month is more an educated guess based on the previous year than on real knowledge.

Of course, most people know that the high season is from December to May and the rainy season from June to November, but with global warming, you get the picture.

We share the usual Phuket weather patterns as best as we can, together with our notes. We hope these will help to choose the best month to travel to Phuket!

Weather Forecast for Phuket


Phuket Weather in January

Peak Season

January weather in Phuket is what we would call ‘perfect’, probably the best month of the year to visit. Rain showers go from rare to none, and the temperature is a cool as it can get.

On the downside, hotel prices are higher, and the island is busy (In recent years, beaches are not as packed as they used to be). On the other hand, the sea is quiet and blue, perfect for your holiday Instagram photos. Cruising the sea to the nearby islands is usually a smooth ride.

Phuket Weather in February

High Season

Phuket Weather in February

In February, the weather in Phuket is quite similar to January; the air is a bit drier and hotter. However, those are the best months to explore the islands around Phuket as the sea usually is calm and clear.

Phuket beaches are usually all clean, the sea blue and pristine (which is not always the case for remote beaches during the low season). On the other hand, the most popular beaches get very busy (Patong, Kata, Nai Harn), so going north to discover the quietest beaches of Phuket is a good idea.

Phuket Weather in April

The hottest month of high season

Songkran Festival Phuket

April sees temperature reaching some of the highest peaks of the year. So if you travelled on a short budget and picked one of the few hostels without air con and just a fan, you better be ready for some hot nights.

April being so hot each year, it is also the occasion to celebrate the famous Songkran festival where people shower each other copiously for several days (and nights). It’s fun for most, but if you don’t like getting wet and party wild, consider avoiding the Songkran week (which dates vary each year).

Phuket Weather in June

Start of the rainy season

Surin Beach

Phuket in June sees the return of the rains; however, it does not rain every day or all day in June, and you will certainly enjoy a lot of sunny days. Unfortunately, the sea sometimes becomes rough or even dangerous, and respecting the red flags is not a warning to take lightly.

Things to do on a rainy day in Phuket

In July, the weather in Phuket is a bit wetter than in June, but you will still get quite a few sunny days. It’s the rainy season, so expect some rainy days, but it doesn’t mean it will rain every day or all day. That’s unless you picked an unlucky week.

Rainy Season

Phuket Weather in October

August weather in Phuket is not much different from July. On the bright side, the island is more peaceful, fewer traffic jams and beaches are all yours. However, the sea can be rough, so respect the flags and pick a hotel with a nice pool and a spa, and you will have fantastic holidays.

Phuket Weather in September

Wettest month of the year

Phuket Weather in September

September is usually the wettest month of the year in Phuket. You can expect more rainy days than sunny ones, but as always, you should get a mix of sun and rain. September is not the best month to travel to Phuket if you want that perfect blue sky and quiet blue ocean, so if you can avoid it, pick another month to be on the safe side. There are still some bright sides if you have no choice: the roads are not hectic, and all the attractions and tours usually open. Except for the Similan Islands, all the islands are open, including Phi Phi Island. When it rains, please bookmark this page we created to keep you busy: 14 Fun Things to Do in Phuket When it Rains.

Phuket Weather in October

Another wettest month

Loi Krathong in Phuket

October weather in Phuket is not much different from the weather in September, again a mix of sun and rain, also not the best month to visit Phuket if you have a choice. However, to be on the positive side, and if you have no choice, this time of the year is the most challenging lucky draw. The rain WILL fall, there is no doubt about it, and as it comes in a series of 3, 6 or 9 days as they always say here. Just pray that it is not during your week!

On the bright side, the beautiful Similan Islands reopen in October, but seas can still be rough.

Phuket Weather in November

Last month of the low season

Phuket Weather in November

The weather in November usually starts to shows signs of improvement. It still can be a mix of sun and rain, but the risk of rain is still quite high. The sea remains rough, and you should keep your eye on the red flags. Booking a hotel with a pool is a good idea. Thailand celebrates the beautiful Loy Krathong in November. Read more

Phuket Weather in December

Peak season

Phuket Weather in December

In December, the weather is usually great unless it’s an unlucky month which tends to happen more often in recent years. Typically, the weather is beautiful: blue sky with tiny clouds and a cool temperature. 24 C is considered ‘cold’ by locals or those who lived here too long. So prices start to switch to the high season rate.
