Swimmer Advice
In the lead-up to Swim Serpentine, we regularly test the water quality and temperature at different locations of the route.
We’re pleased to say that both the water quality and temperature are currently looking good, and we look forward to welcoming you to Swim Serpentine on Saturday 19 September.

- 9 September: The water temperature at midday was 19°C
- 11 September: The water temperature at midday was 19.8°C
- 14 September: The water temperature at midday was 20.1°C

Micro-biology test results show the water quality is Excellent in places close to the swim route. A low level of blue-green algae, which is typically found in the lake during the summer, is significantly below the World Health Organisation (WHO) limit. Our modelling suggests this will continue to decrease as the week progresses.
You can find more information on blue-green algae here.
