Bangkok has a tropical climate characterized by high temperatures, strong sunshine, and seasonal rainfall. The city is warm throughout the year, with daytime temperatures rarely dropping low, even during cooler months. Humidity is a constant factor, especially during the rainy season, making weather awareness an important part of trip planning.
Unlike destinations with four distinct seasons, Bangkok weather is shaped by three main periods: a cooler dry season, a hot season, and a rainy monsoon season. Each offers a different travel experience, affecting sightseeing comfort, hotel prices, and overall pace of the city.

Bangkok Weather by Season
Bangkok weather is best understood through its three main seasons. Each season affects temperatures, rainfall, crowd levels, and travel comfort in different ways.
Cool Season (November to February)
The cool season is the most comfortable time to experience Bangkok weather. Temperatures are lower, humidity drops, and rainfall is minimal, making sightseeing much easier. This period is ideal for walking tours, temple visits, and outdoor markets.
Because conditions are pleasant, this is also peak travel season. Flights and Bangkok hotels tend to be more expensive, and popular attractions can be busier. Still, for many travelers, this is the best time to visit Bangkok based on weather alone.
Hot Season (March to May)
The hot season brings the highest temperatures of the year. Bangkok weather during these months can feel intense, especially in the afternoon, with strong sun and high humidity. Sightseeing is still possible, but planning activities for early mornings or evenings is recommended.
This season works well for travelers who don’t mind heat and prefer fewer crowds. Hotel prices may be slightly lower, and indoor activities, shopping malls, and rooftop dining become popular ways to escape the heat.
Rainy Season (June to October)
The rainy season is influenced by monsoon weather, bringing higher humidity and regular rainfall. Bangkok weather during this time usually includes short, heavy showers rather than constant rain, often in the late afternoon or evening.
Despite the rain, travel remains very possible. Landscapes are greener, crowds are smaller, and hotel deals are easier to find. With flexible planning and proper clothing, many travelers enjoy visiting Bangkok during the rainy season.
