Plymouth Beach Slick Cleared, Swimmers Warned
30 May
Summary
- A rainbow sheen warning was issued for Firestone Bay swimmers.
- The Environment Agency advised against bathing temporarily.
- Natural tide and wave action dispersed the slick, lifting the warning.

Advisory against swimming at Firestone Bay in Plymouth has been lifted following the dispersal of a rainbow sheen on the water. The Environment Agency had issued temporary advice against bathing after the slick was reported, despite the bay consistently receiving excellent water quality ratings since 2023.
The slick was dispersed naturally by the tide and wave action, leading the Environment Agency to remove the advisory. Firestone Bay officially received bathing water status in 2023, enabling regular testing during the summer season, a development welcomed by locals who have frequented the spot for years.
