Bangkok weather in April – what to expect in the capital
April in Bangkok is one of the hottest months of the year. So you should be aware that you will be sweating a lot both during the day and at night.
On the other hand, one of the most exciting cultural festivals in Thailand awaits you this month: the Songkran Festival.
For travelers visiting bustling Bangkok this month, the weather offers both challenges and unique opportunities to experience the city from a completely different perspective.
Bangkok temperatures in April
April is the peak of the hot season in Bangkok. The average daily highs are around 35 to 38 °C, although temperatures can often climb even higher in the midday heat.
It also stays warm at night, with lows of around 26 to 28 °C. These consistently high temperatures make April a challenge for anyone who is not used to a tropical climate.
Important to know: Plan outdoor activities early in the morning or late in the afternoon to avoid the intense midday heat.
Tip: Book a guided tour to the main sights of the city to learn more about the history of Bangkok.
Precipitation in April
April marks the transition from the dry to the rainy season in Bangkok, which is why the probability of rainfall increases compared to the previous months.
On average, there are around 8 to 10 rainy days a month, although the rainfall is usually short but intense.
A typical shower rarely lasts longer than 30 minutes and provides a pleasant cooling effect afterwards.
These downpours often occur in the late afternoon or evening, so you can usually enjoy your activities during the day without interruption.
Despite the short duration, the rainfall can be heavy and flood roads in a very short time, causing traffic challenges.
It is therefore advisable to always have an umbrella or a light rain jacket with you.
Humidity in April
Humidity in Bangkok reaches high levels in April, ranging between 65% and 80%.
The humid air intensifies the feeling of heat and can be unfamiliar to visitors, especially if you come from temperate climates.
Due to the combination of high temperatures and humid air, the weather often feels oppressive, even when the sun is not shining.
Especially at midday, the high humidity can put a strain on the body, as sweat evaporation becomes more difficult and the body has to expend more energy to cool down.

The combination of high temperatures and high humidity can be very exhausting, especially for travelers who are not used to tropical climates.
Even short walks in the midday heat can be sweaty. Wear light, breathable clothing made of cotton or linen and avoid synthetic fabrics.
Important to know: Drink plenty of water to stay hydrated and use air conditioning in cafés, shopping centers or public transport to cool down in between.
One positive side effect is, of course, the decrease in tourists in the bustling city. Hotel prices are also tending to fall.
