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. 0.9m 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.
  • Our main and learner pools are not heated, they are usually is 1-2 degrees above sea temperature.
  • 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 has additional UV filtration in place to maintain the water quality in higher temperatures.
  • Our geothermal pool is heated to 30-35 degrees via our own 410m deep geothermal well.
  • The geothermal system operates by extracting warm water from the geothermal well taking heat out of that water using heat pumps and distributing it to the pool via a heat exchanger, before re-injecting the cooler water back into the ground.  
  • This combined system means that the temperature of the pool can be sustained with a very low carbon footprint. It is the first of its kind in the United Kingdom and will act as a showcase for geothermal, low carbon heat supply.
  • Jubilee Pool has a capacity of up to 600* swimmers, depending on lifeguard levels.  The geothermal pool can accommodate up to 50* persons per session.


* These are normal capacity levels.  Capacity may be restricted as we continue to socially distance.

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 learner 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.  To allow for these drain downs, and to enable us to carry out weekly deep cleans of the site we will be closed every Monday.  

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