This spot’s record
Llandudno North Shore is in Conwy, about 8 km from Colwyn Bay. Llandudno North Shore was rated Good in 2025 by Natural Resources Wales. Its previous classifications were Sufficient in 2024, Sufficient in 2023 and Good in 2022, so the rating here has moved rather than held. Across the 11 most recent samples published by Natural Resources Wales, E. coli counts ranged from 10 to 136 per 100 ml. The highest was taken on 11 September 2025. 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.
