Pattaya, in the northernmost part of the Gulf of Thailand, shares the same weather as the rest of the country. Like all tropical countries, the weather in Thailand is hot all year round, and the weather in Pattaya isn’t any different. It has mainly three seasons: the hot season, the cold season and the rainy season. During the rainy season, the entire country goes through a period of heavy rainfall.
The three seasons in Thailand, to a foreigner, really translates to the hot season, the hotter season and the hottest season. The weather in Pattaya in the Chonburi province of Thailand is often described as hot and humid. Near the sea, Pattaya enjoys light breeze, which help relieve the heat on a sultry day. The sea breeze also makes the temperature in Pattaya slightly different from the temperature in central Thailand. The temperature in Pattaya peaks at 29 degrees Celsius, which is the average temperature in mainland Thailand during the rainy season.
- The Cool Season. The cool season starts from November to February, and sometimes running through the end of March. The temperature goes as high as 30 degrees Celsius in the day and usually 20 degrees Celsius at night. It rains rarely in Pattaya during the cool season and because it’s cooler, tourists generally flock Pattaya at this time of year.
- The Hot Season. The hot season begins at March and ends in May. April is the hottest time of the year with a temperature averaging high at 33 degrees Celsius and low between 25 to 27 degrees Celsius. It rains less frequently than during the rainy season but it equally makes the hot scorching weather bearable. Unless you can get acclimatized pretty quickly or are used to a tropical weather, it might not be a good idea to visit Pattaya at this time of year. The sea breezes help alleviate the heat but with such high humidity, the heat can get you feeling very uncomfortable.
- The Rainy Season. The rainy season in Pattaya happens around June and usually concludes in October. The temperature has a low of 30 degrees Celsius in the day and between 25 to 27 degrees Celsius at night. The rains are heavy but short, often lasting for one hour only. The heavy rains also tend to flood the streets of Pattaya and the flood waters usually take an hour to recede. The rain does help in making the temperature cooler, but humidity can still go up to 90 percent, especially in the day.
The best time to visit Pattaya is definitely during the cooler months of November to February. But even though the weather in Pattaya can get low during the rainy season, there’s virtually nothing to do and people usually stay inside until the rain stops. So, unless you don’t mind getting stuck in your room when it is raining and the lack of activity won’t drive you crazy, you might consider visiting Pattaya during the rainy season too. It’s an off-peak season and you’ll get fantastic rates.
