Thailand has entered a year-long period of national mourning following the death of Her Majesty Queen Mother Sirikit on 24 October 2025, at the age of 93. The government has confirmed that national flags will be flown at half-mast for 30 days and civil servants will wear mourning attire for one year, while members of the public are encouraged to dress in black or muted colours for 90 days.

Tourist services, including hotels, restaurants, transport, attractions and entertainment venues, are operating as usual.

The Tourism Authority of Thailand (TAT) emphasises that the country remains open and welcoming, while requesting that travellers observe local etiquette and cultural norms during the mourning period.

Temple-visiting etiquette is highlighted: visitors are urged to dress modestly and respectfully, especially at royal sites and places of worship.

Some major landmarks including the Grand Palace and the Wat Phra Kaew (Temple of the Emerald Buddha) in Bangkok are temporarily closed until 8 November 2025 for royal merit-making ceremonies; other events may be quietly adjusted or postponed to reflect the national mood.

The mourning period offers visitors a more reflective and cultural travel experience: many festivals and celebrations will be scaled down or tone-adjusted, though not suspended.

Domestic and international travellers are encouraged to plan ahead by checking local listings for any changes in event schedules or site closures.

For Australians and other international visitors heading to Thailand, practical advice includes respecting local customs around royal protocol, avoiding loud or festive behaviour at major public sites, and planning flexibility into their itinerary when visiting cultural hubs such as Bangkok, Phuket or Chiang Mai.

The TAT reiterates that Thailand remains fully operational, but emphasises awareness of the national tone of remembrance during this period of reflection.
