Some of you may have noticed “green gunk” and unsavoury smells when swimming in our beloved lake recently. It turns out that it was more than the usual end-of-summer green vegetation mass die-off.

We are sorry to inform you that swimming is closed at the Serpentine Swimming Club as of tonight until further notice as The Royal Parks have notified us of a blue green algae bloom.

Blue green algae can cause severe skin rashes, eye irritation, vomiting, diarrhoea, fever and pain in joints and muscles. As a result, the gates to the swimming area will be shut tonight, and not open until further notice.

  • If you are on this week’s wardening list, please hold off until swimming resumes.

  • If you were planning on swimming this week, please make alternate plans elsewhere.

Please note that we do not have any definitive information on how long this bloom will last, but based on a previous episode over twelve years ago, we are looking at a few days without swimming. 

In the meantime, rest assured that we will keep you updated on the water quality and hope to return to swimming as fast as possible.
