More than one day in two has at least 1 mm of rain, and August is one of the least sunny months of the year. Showers are often short but heavy: low-lying streets can flood within minutes and traffic grinds to a halt. The BTS Skytrain and the MRT metro remain the safest way to get around, see transport in Bangkok.

Crowds and prices in August

Crowds are average to low and hotels charge low rates, especially outside weekends. Queues at the major sites are short; floating markets and excursions may be shortened or rescheduled because of rain, so check the forecast the day before. On the Mother's Day weekend many Thais travel: book trains and buses in advance. For your neighbourhood, see where to stay in Bangkok; for spending, the Bangkok travel budget.

The event of August 2027

Mother's Day: Thursday 12 August

12 August is the birthday of Queen Mother Sirikit and, in Thailand, Mother's Day. In 2027 it falls on a Thursday: public holiday, banks and government offices closed, while shopping centres, markets and restaurants stay open. Tradition is to give white jasmine to one's mother; official ceremonies take place around the city. Temples and royal sites ask for sober, covering clothes, see what to wear to visit Bangkok's temples.

The Buddhist Lent, which began in late July, continues until October. It does not close the temples, but the monks stay in their monasteries. For the year's festivals, see the calendar of festivals and events.

What to wear and pack in August

  • Light, quick-drying clothes and a spare outfit in your bag.
  • A compact umbrella or a poncho and sandals that cope with water.
  • A waterproof pouch for documents and phone.
  • A light long-sleeved shirt for temples and air conditioning.
  • Mosquito repellent: the rainy season is dengue season, see health in Bangkok.
