Hong Kong's Leisure and Cultural Services Department announced on September 30, 2026, that the Environmental Protection Department had classified the water quality at Golden Beach in Tuen Mun District as Grade 2. According to the department, that grade means the water quality has improved and the beach is suitable for swimming, and the red flag was lowered.

The red flag had been hoisted at the beach earlier because the water quality was classified as Grade 4, which is unsuitable for swimming. The announcement was issued for TV and radio stations to broadcast as an item of interest to swimmers.
