Cardiff sea conditions for swimming, paddleboarding and kayaking
Cardiff forecast for 8 November 2026: Clear, 6.7°C, 14% chance of rain, 2.5 mph ESE wind. Updated 8 Nov, 16:21 UK time.
Cardiff’s nearby waterfront is shaped by the Severn Estuary, Cardiff Bay and the Bristol Channel coast beyond the city. Water movement, mud and wide tidal variation can differ between the bay, river approaches and open beaches, so match the forecast to the exact place you intend to visit.
Local practical checks
- Check whether your destination is Cardiff Bay, an estuary approach or an open South Wales beach.
- Allow for large tidal changes and estuary channels when planning access and travel.
The outlook uses provider-backed weather and tide information for Cardiff and the nearby South Wales coast. Use the day selector to compare the returned forecast days. A suggested window is planning information, not a safety decision.
