Thailand Weather and Climate

 

   Thailand Climate and Weather Overview 

 

Known for its tropical beaches, Thailand is a large country with high temperatures and humidity along with a monsoon season that is responsible for its lush jungle environment. The attraction of its beautiful beaches, jungles, royal palaces and temples makes Thailand a must-see location for all.

It is recommended that the best time to visit Thailand is from November to March as the monsoon season is over and the hot temperatures are yet to arrive. The climate and weather, combined with the festivals and events that occur in Thailand at this time, make November to March an excellent time to visit the country and the perfect conditions to work on your tan, snorkel or visit the local markets and tourist attractions. Although temperatures can reach very high numbers, beachwear should stay on the beach. Informal dress is acceptable in Thailand, however short or revealing clothes in major cities should be avoided out of respect. Modesty is important! If you are planning on exploring the many luscious jungles Thailand has to offer, make sure to get yourself a good pair of walking boots and long sleeves to protect against mosquitos.

 

   Northern and Central Thailand

 

The north and central areas of Thailand have a subtropical climate.  The summer season runs generally from March to June with northern and central Thailand experiencing high humidity and little rainfall. Temperatures can soar up to 40°C but average just below at 37-38°C and there is little rest from the heat at night time as temperatures drop to just 28-29°C.

The rainy season may begin early in June, but for most of the north, is from July through to October. For most rainy day, the day will start off sunny and heavy rains or thunderstorms will arrive later in the afternoon/evening. The rainy season has more humidity than the summer season so the rains and thunderstorms provide some, often much needed, relief from the heat.

The winter season in northern-central Thailand runs from November to February and is favoured as the most pleasant time to visit. This is because the weather is cooler (by no means cold) and humidity drops by 50-60%. The skies are clear and the average daily temperatures sits between 30-33°C with lows of 20-22°C.
