What you'd want to know
Open-water swimming reservoir in Woodberry Down, Hackney — a 24-hectare water body operated by Better as part of the West Reservoir Centre. The reservoir is bordered on the north by 1930s Art Deco Stoke Newington Pumping Station buildings and on the south by the modern Woodberry Down housing scheme glass towers. The swim area is buoy-marked: a 200m winter loop and a 450m summer loop. Entry from a pebbled beach and timber pontoon on the west side. A small modern centre building with changing rooms, hot showers, lockers and a café sits on the bank. Parakeets and ducks on the water; reeds and willow at the margins. Lifeguards in kayaks patrol the loops. Open 365 days; water drops to around 4°c in deep winter.
Overheard
- winter loop is 200m; summer loop is 450m. when the air drops, the loop shortens — don't expect a long swim in january.
- sessions are fully supervised by kayak lifeguards. you'll be told the max swim time as you arrive — it's based on water temp, not your fitness.
- year-round swimming without a wetsuit is allowed (since 2023). most regulars go skins through winter but neoprene gloves and socks are standard.
- the staff genuinely look after you in winter — they check you before and after. it's not the busy queueing model.
- stoke newington regulars come midweek mornings. weekends pull more first-timers; weekday before 9am is the quietest window.
