Thailand’s Weather

The Forecast: Hot, Hotter, and Hot & Wet

The tropical climate of Southeast Asia, high both in temperature and humidity, does not have seasons that many Westerners would recognize. Rather, the weather is often drolly described as hot, hotter, or hot and wet. Upon your arrival in mid-summer, the infamous monsoon season begins. While the heaviest rains do not occur until September to October, the humidity is high, and infrequent showers can occur throughout the day. By November the weather begins to shift into the cool season, which lasts until February. During these months the temperatures are more tolerable, and in the evenings it may even cool enough to open windows and leave air conditioners off. Once the temperatures begin to rise again in February to March, however, they become the norm again as the hot season begins.

For those seeking adventures outside of Bangkok during breaks, more moderate temperatures can be found in northern Thailand, particularly in the mountainous regions around Chiang Mai. The many island beaches around the Gulf of Thailand can also provide respite, or at least the option for a swim during warmer months.

This live weather forecast should give a sense of what to expect at the current time of year in Bangkok. Keep in mind that the weather can change rapidly on a daily basis.

Bangkok Air Pollution and AQI

Bangkok Air Pollution & AQI

Like many other major cities across Asia, Bangkok unfortunately suffers from periods of high air pollution. This tends to occur most frequently during the cooler season from late November to early February, and air quality index (AQI) levels can spike around 200. Multiple factors contribute to this, including crop burning, heavy traffic, weather patterns and industrial emissions. At NIST we maintain a clear air pollution policy and have invested in technology to safeguard the health of our community, including air purifers equipped with HEPA filters in all learning spaces.

More information about air pollution can be found on the NIST website. 

Dress Code at Bangkok International Schools

When preparing for your move, we highly recommend that you leave sweaters, winter jackets and other heavy clothing behind unless you plan to travel frequently to cooler climates. For the typical Westerner, Thailand’s climate means that light clothing will almost always be appropriate. The tropical sun can be quite fierce, so it’s worth saving some space in your suitcase for your favorite sunglasses and hat, and good sunscreen (which is often more expensive in Thailand).

Unlike many international schools in Bangkok, we do not require overly formal dresswear on a daily basis, such as ties or long dresses. You are professionals, and we trust that you’ll maintain good judgment. Our dress code is fairly broad, and in line with our inclusive culture, we maintain a gender neutral policy that can be summed up as “dress appropriately”.

The specific guidelines below are drawn from the NIST policies and procedures documents.

Dress Code Guidelines

  • All clothing should be clean, neat and tidy in appearance – pressed if necessary.
  • Modest “non-revealing” clothing (i.e., no see-through clothing or low fronts, short skirts or tops, or spaghetti straps) is the standard.
  • T-shirts should not be worn.
  • Logos on clothing should be discreet and should not advertise any particular organization or event. NIST logos are acceptable.
  • Shorts (with the exception of the early years and year 1 teachers, who may wear knee-length shorts) and jeans should not be worn.
  • Running/tennis shoes and sportswear should not be worn, except by physical & health education teachers and staff.
  • Sandals should not be worn, and footwear should be regularly cleaned, neat and tidy in appearance.
  • Visible body piercings are to be removed save for unobtrusive nose studs and earrings.
