Diwali on the Square at Trafalgar Square Cancelled Due to Storm Safety Concerns

The Mayor of London's annual Diwali on the Square festival has been cancelled, with organisers announcing the decision on 24 October — just one day before the event was due to take place. The free celebration had been planned for Sunday 25 October 2026 at Trafalgar Square, running from 1pm to 7pm.

The cancellation followed advice from independent event health and safety experts, who warned that storms forecast for the Saturday before would make it unsafe to carry out the build and set-up required to stage the event. Organisers said the safety of everyone involved was the absolute priority and that the decision had not been taken lightly.

The event had been set to feature a colourful opening dance sequence with 200 dancers, a main stage showcasing music and performances from London's Hindu, Sikh, and Jain communities, family-friendly activities including puppet shows and dance workshops, and a market with vegan and vegetarian food stalls. Diwali on the Square is delivered in partnership with the Diwali in London committee.

Organisers acknowledged the disappointment felt by those who had been looking forward to the celebrations, as well as the volunteers who had dedicated significant time and effort to preparing for the event. They said they are now considering other ways to support people in celebrating Diwali in London this year.
