Sea Swim Group

This is a mixed-ability group suitable for all standards, from dippers through to channel swimmers.

Join this session if you:

1. Have experience of sea or cold-water swimming
2. Are looking to sea swim with safety cover and expert guidance
3. Want to experience the benefits of “Blue Mind” and cold-water immersion in a safe environment

Sessions focus on developing sea swimming technique, building endurance, and improving sea safety awareness.

Swimmers will typically cover between 50–1500m per session, with time in the water lasting approximately 20–30 minutes. The group will split where needed to support different abilities and swimming speeds.

This is a coached open water session based at Firestone Bay, Royal William Yard. We meet by the tidal pool at Devil’s Point. Safety cover is provided by a qualified lifeguard.

Date & Time: Session-specific (book and pay per session)

Location: Firestone Bay (meeting point: tidal pool at Devil’s Point)

Swim hats are provided. You are welcome to bring your own tow float. Ace Swimming hats are also available to purchase, please contact us for details.

Wetsuits are optional. If you wish to swim without a wetsuit, please contact us before booking so we can discuss suitability.

Sea temperatures in Plymouth vary significantly across the year, shaping the experience and preparation required. Winter (January–March) typically sees temperatures around 8–10°C, requiring full cold-water precautions and shorter, controlled sessions. Spring (April–June) gradually warms to 10–14°C, allowing swimmers to build confidence and duration. Summer (July–September) offers the most comfortable conditions at 15–18°C, ideal for longer swims and technique work. Through autumn (October–December), temperatures drop from around 16°C back towards 10°C, providing an opportunity to extend the season while gradually reintroducing cold-water adaptation. Sessions are adapted year-round to ensure safe, effective, and enjoyable swimming.

While support is provided in the water, swimmers are responsible for warming up after the session. Please bring warm clothing and ensure you wrap up promptly after exiting the water.

We do not take responsibility for arrival or departure. Please remain mindful of others on land and avoid unnecessary crowding.
