Advisory for all business visitors, tourists, and the general public in Thailand during the mourning period

While the Cabinet has not issued any order to suspend public activities, entertainment events, or business operations, organisers are encouraged to exercise discretion and adjust event formats appropriately in the 30-day mourning period, effective 25 October.

The Royal Thai Government announced a period of national mourning earlier this week, following the passing of Her Majesty Queen Sirikit, The Queen Mother, on 24 October 2025 (Friday).

According to the Public Relations Department, Prime Minister Anutin Charnvirakul has instructed all government offices, state enterprises, and educational institutions to lower the national flag to half-mast for 30 days, starting from 25 October 2025. Government officials and employees, as well as state enterprise employees, have been told to observe a one-year mourning period, effective the same date.

In an update on 26 October, the Tourism Authority of Thailand said while the Cabinet has not issued any order to suspend public activities, entertainment events, or business operations, organisers are encouraged to exercise discretion and adjust event formats appropriately to reflect the national atmosphere of mourning.

"The Government understands many in the entertainment, tourism, and hospitality sectors may have planned activities and events in advance. Businesses are therefore advised to proceed with sensitivity and make suitable adjustments to ensure decorum and to honour Her Majesty’s memory."

During this period, the formats of TAT-organised events will be adjusted, with festive and celebratory elements postponed until further notice.

Thailand remains open and fully operational during the mourning period, and all tourist attractions, transportation services, restaurants, shops, and events continue as usual.

Members of the public are encouraged to dress in black or subdued colors for 90 days, since the color symbolises solemnity and respect for the late Queen Mother. As a gesture of respect, tourists vising Thailand during this period are also encouraged to wear somber colors (black, white, gray, or dark blue).

Dress code for those paying respects to the late Queen Mother

The PRD has shared the following dress code requirements for those who wish to pay their respect to the late Queen at the Sala Sahathai Samakhom Pavilion in the Grand Palace:

• Men: A black shirt with collar, or a white shirt with a black necktie, black long trousers, and closed-toe shoes;

• Women: A black loose-fitting sleeved top, with a black knee-length skirt, or sarong, and closed-toe shoes;

• Students: A uniform.

Jeans, t-shirts, sleeveless shirts, and shorts are not allowed.

Citing the Bureau of the Royal Household, the PRD said members of the public are permitted to pay their respects to the late Queen Mother in front of her portrait at the Sala Sahathai Samakhom Pavilion, from 8:30am to 4:00pm, from 27 October onwards.

From 9 November, after the royal merit-making ceremony marking the 15^th day since the passing of the late Queen Mother, they will be allowed to pay their respects in front of the royal urn at Dusit Maha Prasat Throne Hall, between 9:00am and 9:00pm.

Members of the public are encouraged to dress in black or subdued colors for 90 days, since the color symbolises solemnity and respect for the late Queen Mother.

As a gesture of respect, tourists vising Thailand during this period are also encouraged to wear somber colors (black, white, gray, or dark blue).
