Bangkok has a tropical savanna type of climate (Köppen climate classification Aw) with hot and humid summers, wet rainy periods, and warm winters.
Bangkok, the capital of Thailand, lies in central Thailand, in the Chao Phraya River delta. The city lies in the proximity of the Gulf of Thailand, which influences its climate. Bangkok is at a low altitude, only about 1.5 meters above sea level, and lies in the tropical latitudes, which keep the temperatures warm throughout the year.

Bangkok, the Venice of the East, has numerous canals that serve as transport routes and drainage channels. The topography is flat in the absence of mountains, and most of the lands are swamplands converted to agriculture lands. Annual rainfall is 1651mm (65") - precipitation occurs mainly in the wet season from May to October, while the rest of the year hardly sees 15% of the total rainfall. Bangkok registers 2623 hours of sunshine during the year. The average humidity ranges from 66% to 79%, and the city is warm throughout the year.

Bangkok has three seasons: hot, wet, and cold. The tropical location is responsible for reasonably hot temperatures all year round. The hot season is from February to April, is mostly dry, with average the high temperatures of 35.6°C (96.1°F) at the peak of April. Scorching days register in April and May before the arrival of the monsoon, with temperatures often crossing 37.8°C (100°F). Bangkok exhibits the urban heat island effect, albeit to a lower extent than other parts of Thailand owing to its proximity to the sea.
The southwest monsoon ascends over Bangkok during the wet season from May to October, bringing heavy rainfall along with it. Heavy rain and stormy weather are evident in the season as it rains almost every day or two. The cold season is from November to January when Bangkok has pleasant weather, and the average low temperature is 21.7°C (71.1°F) during December.

The best time to visit Bangkok is from November to January when the temperatures are relatively mild during the winter, and the rainfall is negligible.
The average humidity is at the lowest levels of the year during the winter. The dry months, clear skies, and lack of stormy weather make the season pleasant and stay comfortable.
Winter months seldom go below 15.6°C (60.1°F) to 21.1°C (70°F), and the days are bright with ample sunshine.

April to October is usually the worst time to visit Bangkok as the temperatures are high, and the precipitation is heavy.
The wet season punishes the region by unleashing profound spells of rains. The conditions are humid and mostly cloudy. Floods are common, and Bangkok sometimes submerges into the water for long periods. Add tropical storms to the equation, and the wet season becomes the worst time to visit Bangkok.

Bangkok is prone to thunderstorms, tropical cyclones, typhoons, and floods, mainly during the rainy period from May to October. Thunderstorms are frequent in the region with lightning and rain. Tropical cyclones of variable strengths originating in the Indian Ocean travel to Bangkok, make landfills, and cause devastation on occasions. Torrential rains during the wet season flood Bangkok regularly as the city is at a low elevation, drainage systems are insufficient, and subsistence is a severe issue.
