Thailand has officially entered a period of national mourning following the death of Her Majesty Queen Sirikit The Queen Mother on 24 October 2025. The Royal Household Bureau confirmed that she died in a Bangkok hospital after developing a blood infection on 17 October, and the Crown has directed that flags fly at half-mast for 30 days and mourning attire be observed by government officials for one year.

While daily life, commerce and tourism continue, the Thai Government has requested that citizens and visitors alike show respect through dress and conduct.

Government offices, state enterprises and schools are instructed to fly the national flag at half-mast for the next month, and the public is encouraged to wear black or subdued colours for 90 days.

The Cabinet clarified that there is no official ban on private entertainment or tourism activity, but organisers are asked to adjust formats of planned events to reflect the national mood.

The Ministry of Culture and Tourism Authority of Thailand have issued guidance that any celebrations be toned down, colorful displays be moderated and digital and social-media content adopt respectful messaging.

Tourist attractions remain open, and visitors are welcome.

Some royal or ceremonial sites may have temporary restrictions or closures ahead of official merit-making and cremation services.

Attractions such as temples, museums and historic sites continue operations, though travelers are advised to check ahead for any event-specific changes.

For those planning to travel in this period, the etiquette is straightforward: dress modestly and in dark or neutral colours, refrain from loud or exuberant behaviour, and respect any local adjustments to event schedules.

While Thailand remains open for tourism, this interval presents an opportunity to engage with local culture and heritage in a quieter, more contemplative mode aligned with the nation’s sentiment.
