Thailand has a tropical climate with a distinct monsoon season, which means that whatever time of year you visit, it’s going to be warm and humid and might be wet.
There are three seasons in Thailand --
cool season between November and February,
hot season between March and May
and rainy (monsoon) season between June and October.
Heat, humidity and rainfall vary significantly depending on where you’re traveling and what time of year you come.
When is the best time to visit Thailand?
Generally speaking,the best time to visit Thailand is from November to February when the northeast monsoon is blowing cool, dry air that serves as a respite from the heat. During this cool season, the temperature ranges from 18 to 32 degrees Celsius in Bangkok, while in northern and northeast Thailand, temperatures can get quite cool with morning temperatures as low as eight to 12 degrees Celsius with the occasional 20 degree day. Nights can be particularly chilly and at high altitudes .
The summer period, or hot and dry season, is from March to June. At this time temperatures in Bangkok average around 34 degrees, but can often reach 40 degrees with humidity levels of 75%.
Try and avoid April, unless you plan to be permanently submerged in the ocean, because this is the hottest month across the country.
From July to October is the monsoon, when most of Thailand's annual rainfall is accumulated and flooding can ravage the country. The humidity averages just under 90%, with temperatures averaging around 29 degrees Celsius in a very wet and rainy Bangkok.
But in my own experience I have visited Thailand mostly in July and august and enjoyed almost ever time a nice and hot weather, with some rainy days but always full of fun . So if you are planning to visit Bangkok don't hesitate because of the weather just pack your bag and go enjoy life in the land of smiles.
