Penarth sea conditions for swimming, paddleboarding and kayaking

Penarth forecast for 28 October 2026: Patchy rain nearby, 11.2°C, 28% chance of rain, 14.3 mph WSW wind. Updated 28 Oct, 06:08 UK time.

Penarth overlooks the Severn Estuary, with a pier and promenade along its beach. Cardiff Bay and the open estuary shoreline are nearby but distinct water environments with different access arrangements.

Local practical checks

Separate a visit to Penarth beach from a route inside Cardiff Bay.
Check tide height, local access and estuary guidance as well as the predicted high-water time.

The outlook uses provider-backed weather and tide information for Penarth and the Severn Estuary coast. Use the day selector to compare the returned forecast days. A suggested window is planning information, not a safety decision.
