Is the sea water quality good in New Forest?

New Forest has a Gera Bathing Water Score of 100/100 (4 of 4 rated sites Excellent, 1 Poor) for the 2025 season. A GBWS of 100 reflects a combination of current classification (weighted 60%) and multi-season consistency across all assessed seasons, up to six from 2019–2025 (weighted 40%). This is a high score, indicating consistently good water quality across the area.

What does the Gera Bathing Water Score mean?

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.
