Bangkok has a tropical monsoon climate and generally remains hot and humid throughout the year. Bangkok has three seasons: hot, rainy, and “cool” and dry.
The coolest and driest months are December and January, with almost no rainfall and an average low of 22°C (72°F) and high of 31°C (88°F), so still warm, but not so hot.
The hottest month is April, with an average high of 35°C (95°F) and low of 27°C (80°F). The high rainfall starts around mid-May and reaches its maximum in September.

Best Times to Visit Bangkok
Though Bangkok is a year-round destination, the best time to visit Bangkok weather-wise is from November to February. The weather is not-so-hot and mostly sunny, which is very suitable for sightseeing.
You will find big discounts if you travel between June and October due to the rainy season. It is usually the cheapest time of year to go to Bangkok.
If you want to experience Thailand's top festivals, then come in April or November, which are the months for Thai New Year (a.k.a. Songkran Festival) and Loy Krathong respectively.
In the middle and end of the year, Bangkok, the shopping paradise, offers attractive discounts at major shopping malls.

Three weeks encompassing Vietnam
A special shoutout to our last guide in Bangkok - Ms. Ka-Noon who spoiled us with her kindness and then got us through check in and security for our flight home in record time at that huge Bangkok airport. MoreDeby, Feb 2023

Three weeks encompassing Vietnam
Three weeks encompassing Vietnam, Cambodia, Thailand and Laos. Albee Ning arranged everything perfectly. Not a flaw in the whole 3 weeks. Guides, flights (7 in total), hotels, private tours…everything was excellent. Travelling on a private tour gave us so much freedom to change our day if we chose to rest or go somewhere else.

Over the last 5 years we've used Asia highlights twice. And both times we've had fantastic vacations. Would not want to do it any different when we travel to Asia from now on. Sharon was fantastic. She was a wonderful agent who helped us nail down our trip and make everything go as smooth as possible. MoreTodd Atwell, Feb 2023

Family Trip to Thailand
Our trip to Thailand comprised three generations of the family , ten people and an age range of 4 to 70 so a potentially difficult brief.Our itinerary over two weeks involved four locations, and a number of different trips and tours.From out arrival at an extremely busy Bangkok airport Asia Highlights were terrific.In each location we were met by a smiling , knowledgeable and professional guide who simply made everything easy and stress free for everyone.Our transportation was clean and comfortable . Transport was always ready for us at the agreed time and the drivers were excellent.There were so many highlights enjoyed by all the age groups. The floating houses , railway market and elephant sanctuary were particular favourites.We had one minor glitch with the accommodation in Phuket which was immediately dealt with by Tip. I think we would have struggled to resolve the problem by ourselves. So, thank you Asia Highlights , Cathy, Tip and tour guides Tanny, Sam and Lisa. It was a memorable holiday and we will be back.

Trip of a lifetime from Asia Highlights!
I recommend highly Asia Highlights as a travel company. Our travel consultant Albee took the time to connect with us during the planning process to make sure we were comfortable with our itinerary. When we arrived, we were met by our guide and all the details were attended to. They picked great hotels and tours. I often describe our trip as the trip of a lifetime! Would definitely use them again when we come back to Asia MoreNancy Parker, Feb 2023

Asia Highlights and Albee - highly recommended
Asia Highlights is very reliable agency and Albee is an amazing representative of the company. From the moment when we contacted her until our departure, the whole support we received was 6* level. She prepared our trip offer within few hours and afterwards she was extremely flexible to adjust as per our needs. In the period between the offer and the trip, Albee was always available for all our questions and supported us on the best possible way. During the trip she was again flexible to add new activities/transfers and this went on the smoothest possible way. Thank you, Albee and Asia Highlights. Definitely we will approach you again for our next Asian trip MoreAZ, Feb 2023

The Worst Times to Visit Bangkok
Located in the tropics, Bangkok can be scorching and humid on some days, which would be the worst time to visit if you can't stand that sort of weather.
- April and May are times to avoid if you don't like scorching heat and a muggy feeling.
- September to early October is the rainiest time. If you don't like the rain, then this is the period you should avoid.
However, at those times you can find the most favorable prices and enjoy less-crowded attractions.
The heat can also be avoided as much as possible by organizing your schedule wisely.
Although rain is a bit of a nuisance, it usually rains in the late afternoon or early evening. So, it wouldn't affect your whole visit.
>>>Thailand's Rainy Season: When It Is and the 5 Best Places to Go
Peak Season in Bangkok (November to February)

The most popular time to travel to Bangkok is from November to February with its comfortable weather. However, it also brings higher trip costs and large number of travelers.
Bangkok in November — Comfortable with Little Rain
- Average low/high temperature: 24°C/32°C (76°F/89°F)
With nice weather conditions, November is a good time to go anywhere in Bangkok, like visiting the Grand Palace, local markets, and temples.
There is a big festival in November — Loy Krathong. There are lively celebrations in parks, temples, and on rivers all over Bangkok.
Bangkok in December — Coolest Month
- Average low/high temperature: 22°C/31°C (72°F/88°F)
December is the driest and coolest month of the year in Bangkok. It is also the most touristy month.
The end of December brings a festive atmosphere. There are celebrations on Christmas and New Year's Eve in Bangkok. Shopping malls in Thailand have big sales from late December to early January. If you're planning a trip to Thailand over the Christmas and New Year period, try to book as early as possible. Popular hotels are usually booked up 3-6 months in advance.

Bangkok in January — Sunny
- Average low/high temperature: 22°C/32°C (72°F/89°F)

Bangkok in February — Still Nice Weather
- Average low/high temperature: 24°C/33°C (75°F/91°F)
Although the temperature has risen a bit in February, it is still a good time to visit Bangkok because of the lack of rain.
Bangkok's China Town is a good place to visit when it coincides with Chinese New Year.
Shoulder Season in Bangkok (March to June)

Temperatures in Bangkok begin to rise sharply from March, and rains arrive in May.
Although not as many as in the peak season, there are still many tourists for the Songkran Festival in April.
Bangkok in March — Heat Up
- Average low/high temperature: 26°C/34°C (78°F/93°F)
Temperatures heat up in March, especially in late March. However, early March is still suitable for sightseeing. You still can expect more sun and less rain than at other times of the year.
Bangkok in April — Hottest Month
- Average low/high temperature: 27°C/35°C (80°F/95°F)
April is the hottest month of the year in Bangkok. It is also wetter than March.
Songkran Festival (Thai New Year) falls on April 13–15. Though April is not a peak season, the festival still attracts many travelers.
Visiting temples or arranging a morning/night outdoor tour, like a night cruise could avoid the heat as much as possible.
Bangkok in May — Rains Start
- Average low/high temperature: 27°C/34°C (80°F/94°F)
The rainy season in Bangkok begins in May. The combination of rain and heat inevitably creates a muggy feeling.
Relaxing by the pool or in an air-conditioned café can alleviate such feelings.
There are few tourists in Bangkok in May. It is a great time to visit Bangkok for favorable prices.
Bangkok in June — Hot and Wet
- Average low/high temperature: 27°C/33°C (80°F/92°F)
Bangkok in June is a little less muggy than May. Rainfall is moderate and passes quickly.
You could expect less-crowded attractions and shoulder season promotions.
Shopping in an air-conditioned shopping mall is a good choice in June. Bangkok's many shopping malls will have discounts in the middle of the year.
Low Season in Bangkok (July to October)

July to October is the rainy season in Bangkok.
Increasing rainfall makes July to October less touristy. Some travelers take advantage of the opportunity to gain a quiet experience with less costs, though.
Bangkok in July — Moderate Rain
- Average low/high temperature: 26°C/33°C (79°F/91°F)
Traveling in July is not bad. The temperature in July drops a little. Rainfall is at moderate levels.
Rain showers usually come in the afternoon or at dusk. Just plan your trip around this knowledge. Don't worry too much about the impact of rain on your trip.
Bangkok in August — Rain Increases
- Average low/high temperature: 26°C/33°C (79°F/91°F)
Temperatures in August are the same as July's, but rainfall begins to increase at the end of August.
Taking a Thai cooking class, getting a Thai spa/massage, and watching a wonderful cultural performance (e.g. Muay Thai kick boxing) are all good activities for the rainy season.
>>>Top Activities for Thailand's Rainy Season
Bangkok in September — Rainiest Month
- Average low/high temperature: 26°C/32°C (78°F/90°F)
In September, you would see heavy rain/thunderstorms very regularly. Monsoonal rainfall is at its peak in Bangkok.
It is probably the month to get the most favorable prices.
Bangkok in October — End of the Rainy Season
- Average low/high temperature: 25°C/32°C (78°F/89°F)
Finally, in October, Bangkok's rainy season comes to an end. In mid-October, the rainfall starts to decrease.
So, late October is actually quite a good time to visit Bangkok: there's less rainfall, and you could avoid the upcoming peak season, starting in November.
