Facts & Figures

  • Jubilee Pool is the largest and most celebrated sea water pool in the UK.
  • It is triangular with the longest side 98m long and 56m width in the widest part.
  • The main pool depths range from approx. 1.2m to 2.25m depending on the tides.
  • The learner pool depth is approx. 0.6m.
  • The geothermal pool depth ranges from approx. 0.85m to 1.35m.
  • The whole pool contains 5 million litres of sea water.
  • It has no mechanical filtration and minimal chemical treatment for a natural sea water bathing experience and a robust cleaning regime to keep it clean and safe.
  • Our geothermal pool (when heated) has additional filtration and UV in place to maintain the water quality in higher temperatures.
  • Jubilee Pool has a capacity of up to 600 swimmers, depending on lifeguard levels.  The new geothermal pool will accommodate up to 60 persons per session when the heated sessions start operating in November every hour.

Tides & Cleaning

As with other coastal lidos across the country, Jubilee Pool is designed as a seawater pool with no mechanical filtration and minimal chemical treatment.

The quality of the water is carefully a maintained with a regime of daily water replacement that is timed with the outgoing and incoming tides; and the water in the small pool is normally replaced daily when a small amount of chlorine is added. This approach means that the water levels in the main pool are continuously changing and access to some areas may occasionally be restricted.

This programme is also supported by a regular drain down (over 5 million litres of water).  Cleaning and refilling is usually completed during fortnightly higher tides, weather and sea conditions permitting.  This requires a closure of the pool for a day up to every fortnight and visitors should check our signs, website and social media for details of the next shut down.

The quality of the pool water is scientifically tested to ensure we meet the required standards.
