Tips for travelling to Bangkok in January

As you prepare for your January visit to Bangkok, remember a few important Thailand travel tips to make the most of your journey.

What to pack for Bangkok in January

When packing for a trip, consider the warm and dry weather in Bangkok in January. To stay comfortable in the heat of the day, choose lightweight, breathable clothing and be sure to bring sunscreen, sunglasses and a hat to protect you from the sun. 

Evenings can be cooler, so bring a light jacket or cape just in case. If you plan to visit temples and religious sites, take modest clothing that covers your shoulders and knees. In addition to all of the above, a mackintosh or umbrella can be useful as it can still rain briefly at times.

Familiarize yourself with cultural etiquette

To navigate and respect local customs, learn cultural etiquette. 

  • In Thailand, the traditional greeting is a slight bow with palms pressed together called "wai". 
  • As a sign of respect, remove your shoes when entering houses and temples. 
  • Refrain from touching the head, which is considered the most sacred part of the body.
  • When visiting religious sites, dress modestly, covering your shoulders and knees.
  • Accepting or offering objects should be done with both hands as a sign of respect.
  • Refrain from raising your voice and showing anger in public.

Understanding and adhering to these cultural nuances will help you improve your travelling experience in Thailand.

Learn the language basics

In Thailand, it is very much appreciated when tourists learn a few basic phrases in Thai, which improves interaction with locals and contributes to a more immersive travelling experience. A simple hello or a thank you in Thai can go a long way in strengthening positive connections.
