Lyme Regis Church Cliff Beach — FAQ

Is Lyme Regis Church Cliff Beach safe to swim?

Lyme Regis Church Cliff Beach is rated Poor for the 2025 bathing season. This means it does not meet minimum EU Bathing Water Directive standards and may pose health risks. The EA may issue an advisory against bathing. Check environment.data.gov.uk/bwq for current advisories.

What does Poor classification mean?

Poor means the site fails the minimum rBWD standard based on its 4-season assessment window. The EA may advise against bathing. This does not necessarily mean the water is unsafe on any given day, but it is the lowest classification.

What is the Gera Bathing Water Score?

The Gera Bathing Water Score (GBWS) combines two components from Environment Agency rBWD annual compliance classifications (key-free open data, OGL v3.0): (1) latest classification score (Excellent=100, Good=75, Sufficient=50, Poor=25), weighted 0.6; and (2) pass-rate across every assessed season available for the site (up to six: 2019, 2021–2025; the proportion rated Sufficient or above), weighted 0.4. Formula: GBWS = round(0.6 × latest_score + 0.4 × pass_rate × 100). Sites with fewer than 3 assessed seasons are shown as 'insufficient data'. The 2020 bathing season was cancelled due to COVID-19 and is excluded. LA-level scores are the mean GBWS of all sites within the LA that have sufficient data.
