FCDO notice

Severe Flooding

Severe flooding is affecting parts of Thailand following heavy rainfall in a number of provinces, including Bangkok, Nonthaburi, Pathum Thani and Samut Prakan. All 50 districts of Bangkok have been declared disaster-affected areas. Travel disruption, including road closures and flooding of low-lying areas, is possible.

The Thai government has declared special public holidays on 28 and 29 September in Bangkok, Nonthaburi, Pathum Thani and Samut Prakan. Many government offices and services may be closed or operating with reduced capacity. Follow the advice of local authorities if you plan to travel.

Warnings (from the FCDO, word for word)

Your travel insurance could be invalidated if you travel against advice from the Foreign, Commonwealth & Development Office (FCDO).

Areas where FCDO advises against travel

Thailand-Malaysia border

FCDO advises against all but essential travel to parts of the south, near the Thailand-Malaysia border:

• Pattani Province
• Yala Province
• Narathiwat Province
• The districts of Chana, Thepa, Na Thawi and Saba Yoi in southern Songkhla Province

FCDO also advises against all but essential travel on the Hat Yai to Padang Besar train line that runs through these provinces.

This is due to regular attacks in the provinces by the border with Malaysia. See Safety and security .

Thailand-Cambodia border

FCDO advises against all but essential travel to areas within 20km of the land border with Cambodia.

Fighting occurred along parts of the border in July 2025, and further clashes took place in early December, involving rocket and artillery fire. Land borders and crossings between Thailand and Cambodia remain suspended. Tourist sites close to the border, including the Khao Phra Wihan Preah Vihear temple, the Ta Kwai Ta Krabey temple and the Ta Muen Thom Tamone Thom temple, are closed. There are unexploded landmines in the area. Travel to affected border regions should be avoided.

• check travel advice for any countries or territories you are transiting through

• check for the latest updates from your airline or tour operator

• review your travel insurance policy for coverage

• monitor local and international media for the latest information and sign up for travel advice email alerts

• If you have been impacted by travel disruption and need to review your Thai Visa, please follow the guidance published by the Thai Immigration Bureau: Immigration Bureau Facebook

It is illegal to carry cannabis out of Thailand

British nationals have been caught carrying cannabis out of Thailand, including while transiting through other countries. Many international airports have excellent technology and security for detecting illegal items, which may be used to scan the baggage of transiting passengers. If caught you will be arrested or fined.
