This spot’s record
Fontygary Bay is in the Vale of Glamorgan, about 17 km from Cardiff. Across the 12 most recent samples published by Natural Resources Wales, E. coli counts ranged from 10 to 430 per 100 ml. The highest was taken on 7 September 2026. A classification is calculated from percentiles across four seasons, so no single reading decides how this water is rated.

A bathing water's official classification is calculated from percentiles across four bathing seasons, not from any single sample — so one high reading doesn't mean a spot is unsafe, and one low reading doesn't mean it's clean today.
