What is Krabi’s Weather Like in April?
April brings random rain showers – sometimes violent lightning storms – to Krabi’s weather. This begins Thailand’s Rainy Season.
The storms are random and infrequent in April. They come fast and furious and the lightning can be scary. This isn’t a good time to be climbing on mountain tops or Tiger Cave Temple stairs because lightning is a real danger on high points in Krabi.
The same as anywhere else, Krabi’s weather depends on many factors. Find out more below before you plan your trip!
Typical Rain in Krabi in April?
A normal April consists of random rain showers that last no more than an hour. These are very fast moving storms that blow over quickly. There may be 1 or 10 blow through in one day. One never knows. The ocean has built up heat that is causing evaporation at a massive rate. This fills the clouds with rain and it drops quickly. It can come down in torrents.
In Krabi, we usually have about 5-8 days of rain in April. April begins the rainy season and Songkran, the Thai New Year is based around the rain starting to water the rice and other crops for the year.

Is Lightning a Problem in April?
Yes, lightning can be a problem in Krabi during the month of April. April and May are the most dangerous months for lightning strikes. You may see strikes hit nearby ten or more times in a short storm. It’s crazy sometimes, so please proceed with caution in the outdoors during this time.
Take shelter in a building, or a vehicle. Motorbikes are not good protection at all from a lightning storm. They are full of metal, and you’re sitting on it. The tires won’t provide much protection.
Predicting Krabi Weather in April?
We use Accuweather (com) for our online tool, but to be honest it is not very accurate except for large storms that stay for a while. The quick moving storms are not picked up all the time, so it’s frustrating.
Our best way to predict what will happen with the weather in April in Krabi is to see what happened just a few days prior.
If it rained in the morning, we’ll probably get rain in the morning again. If it rained at 4 pm. we’ll probably get the same.
You know? Krabi’s weather goes in couple of day cycles. It’s the best predictor we have. I know that doesn’t help you predict in a month or year what the weather would be like if you book your vacation to Krabi right now, but then nobody can help with that.
April Skies
The sky in April tends to be bright blue and filling with white or dark clouds, depending if it is going to rain or not. The air is mostly clear and clean and great for photos.
In the months of May to September is the ideal time-period to take a hike in Krabi up Ngon Nak mountain to see the views over Ao Nang, Railay, and Phi Phi Islands.
The sky will be clear and sunny approximately 80% of the time during April.
Temperature in Krabi in April?
The temperature in April in Krabi ranges between 25-34°C (77-93°F). Days and nights are hot, sometimes overwhelmingly so. You’ll need air conditioning for sure. The hottest part of the day is between 10 am. and 4 pm. This is not the greatest time to do long treks up Ngon Nak Mountain, or Tiger Temple, so plan those activities during mornings for the best experience and least chance of heat exhaustion. Go early morning!
Temperatures may drop if we get a rain shower, but it will quickly heat up again and possibly get much hotter as the humidity increases a lot after the rain!
Sunblock?
The sun is always strong in Krabi when it is out or behind a thin layer of clouds. If you are sensitive to the sun, or fear cancer, always use a good 50+ SPF sunblock.
