Best (and Worst) Times to Visit Krabi, When is Rainy Season

By Chris QuanUpdated Oct. 8, 2023

Located on the west coast of Thailand (the Andaman Sea), Krabi has three seasons: the hot, rainy, and cool (warm) seasons.

The coolest month is December with an average low of 23°C (73°F) and high of 31°C (88°F), which is still warm. The driest month is February, with almost no rainfall.

The hottest month is April, with an average high of 34°C (93°F) and low of 24°C (75°F). The highest rainfall comes in October.

Best Times to Visit Krabi

The best time to visit Krabi weather-wise is from December to February. The weather is not-so-hot in the evenings, but can still be very warm in the afternoon, and it's mostly dry and sunny, which is very suitable for all kinds of activities.

If you prefer water sports, like snorkeling and diving, March and April are still suitable for a visit. The wind and waves are usually calm and the water temperature is warm.

If you want to find discounts, you could consider traveling in the rainy season, between August and October.

The Worst Times to Visit Krabi

May in Krabi can be muggy. If you cannot stand mugginess, May should be avoided. The muggy feeling is strongest in May, because the moderate rain increases humidity but does not bring the temperature down much (compared to the heavier rain later in the year).

August, September, and October are also times to avoid if you don't like rain, especially October.

But some travelers also choose visit during those times, because there are fewer tourists and great discounts.

However, these "worst" times actually won't ruin your travel plans if they're mindfully and flexibly made. The effects of the rain/heat can be ameliorated by organizing your schedule wisely.

April — Hottest Month

  • Average low/high temperature: 24/34°C (75/93°F)

April is the hottest month. The afternoon sun is very hot. Be careful not to get sunburned when going to the beach.

It is time to play with water! Krabi has a grand water-splashing festival (Songkran Festival) in April. People celebrate the festival with water fights, which also keep the heat away.

May — Rains Come

  • Average low/high temperature: 24/33°C (76/90°F)

The monsoon brings rainfall and also a muggy feeling in May. It is mostly cloudy and overcast.

You can relax in the hotel pool, enjoy a spa, or explore the night market in the evening.

June — Hot and Cloudy

  • Average low/high temperature: 24/32°C (75/89°F)

In June, the mugginess is somewhat relieved. Although June is the rainy season, the rains are not yet at high levels. It is cloudy for most of the day, but outdoor sightseeing is still very possible.

The rain in Krabi is unpredictable. Even in the rainy season, it could be sunny for more than ten days without rain, or you could face daily storms.

July — Still Hot

  • Average low/high temperature: 24/31°C (75/88°F)

The weather in July is similar to June: hot with occasional rain showers. Most activities and sightseeing are good to do, such as visiting a national park, or a temple.

While some water activities are available, like snorkeling, they don't offer the best experience because of the low visibility in the sea and fluctuating currents.

Low Season in Krabi (August to October)


August — Rain Increases

  • Average low/high temperature: 24/31°C (75/88°F)

The temperature in August is the same as July's. But the influence of the monsoons increases. The rain is longer and harder, but it won't last all day.

There are not many people in Krabi during this period, so it is very pleasant to wander around and explore areas like Krabi Town.

September — Second Rainiest Month

  • Average low/high temperature: 24/31°C (75/88°F)

You may see heavier rain in September, but the rainstorms make the surroundings lush and beautiful.

You can go to a spa and relax in a resort on rainy days.

To compensate for the weather, you can find great discounts in September.

October — Wettest Month

  • Average low/high temperature: 23/31°C (74/88°F)

The rain reaches a peak in October, which makes the temperature a little less hot.

It is a good time to take advantage of the quiet beaches and resorts before the peak season returns.
