The Climate

The climate in Bangkok is characterized as a tropical monsoon climate, also known as a tropical wet and dry climate.

Here’s an overview of the climate conditions in Bangkok:

High Temperatures:

Bangkok experiences high temperatures throughout the year, with daytime temperatures reaching or exceeding 90°F (32°C).

The hottest period is typically from March to May, during the hot season.

This period can be pretty uncomfortable due to high temperatures and humidity.


Humidity levels in Bangkok are generally high, especially during the rainy season.

Humidity is often above 70%, making the air feel heavy and sometimes uncomfortable.

The high humidity contributes to the “sticky” feeling many visitors might experience.

Rainy Season:

The rainy season in Bangkok occurs from June to October.

During this period, the city experiences heavy rainfall and occasional thunderstorms.

The southwest monsoon winds bring moist air from the Indian Ocean, leading to frequent showers.

August and September are usually the wettest months.

Dry Season:

The dry season in Bangkok lasts from November to February. This is the most pleasant time to visit the city, as the weather is relatively cooler and less humid.

Rainfall is significantly reduced during this period, and skies are often transparent.

The cool season is a popular time for tourists due to the more comfortable weather.


Bangkok’s climate can be divided into three main seasons:

  • Hot Season (March to May): Very hot and dry.
  • Rainy Season (June to October): High humidity and heavy rainfall.
  • Cool Season (November to February): More comfortable temperatures and lower humidity.


Bangkok is prone to occasional flooding, especially during the rainy season.

The city’s drainage systems can become overwhelmed by heavy rainfall, leading to localized flooding in some areas.

However, major flooding is not a constant occurrence and is often manageable.

Air Quality:

Air quality can be a concern in Bangkok due to pollution, especially during the dry season and periods of stagnant air.

Smog and particulate matter from vehicle emissions and industrial activities can reduce air quality. It’s advisable to check the Air Quality Index (AQI) before outdoor activities.

In summary, Bangkok’s climate is characterized by high temperatures, high humidity, distinct wet and dry seasons, and occasional heavy rainfall.

The best time to visit for comfortable weather is during the cool season, from November to February.

However, regardless of the season, proper clothing, hydration, and precautions against heat and humidity are essential for a pleasant experience in the city.
