St Ives sea conditions for swimming, paddleboarding and kayaking
St Ives forecast for 8 November 2026: Overcast, 11.7°C, 23% chance of rain, 11.4 mph SE wind. Updated 8 Nov, 15:46 UK time.
St Ives sits around St Ives Bay, with the harbour, Porthminster and Porthmeor beaches facing different directions around the town. The bay and surrounding headlands can alter wind and swell exposure, while the harbour and changing sand or beach levels affect access.
Local practical checks
- Name the exact beach or harbour-side access in your plan because the bay is not uniform.
- Compare the forecast with the swell direction and what is happening around the headlands on arrival.
