About Surfing in St Ives Bay, Cornwall
St Ives Bay offers diverse surf experiences depending on your paddling spot. Porthmeor in St Ives, facing northwest into Atlantic swell, delivers punchy hollow peaks when sandbanks align, especially during mid to low tide.
In the main bay, the stretch from Hayle Estuary at the south end to Godrevy at the north consistently catches more swell due to its exposure and wider angle to the Atlantic. Here the waves are generally longer, open and larger. On days when Porthmeor is shoulder-high Gwithian can easily be overhead with size increasing as you move north towards Godrevy Head for a typical westerly swell.
St Ives Bay’s crescent shape provides numerous offshore wind options even in winter as long as the swells are big enough to get into what in summer are normally flat surf spots on the west side of the bay.

Godrevy Forecast Summary
Programmatically generated summary. Hog SaysOnshore wind swell should produce some rideable but messy surf at Godrevy. The partly exposed WSW swell has minimal incoming energy with 13.8–15.5-second periods. The combined sea at the forecast point is around 4.1 ft with 4.1–4.4-second periods. The best wind window is the morning, when a moderate cross-offshore breeze around 17 mph should keep conditions fairly clean. Wind is least favourable in the afternoon, when a fresh cross-onshore breeze around 19 mph is likely to make conditions very messy and turbulent, with many whitecaps and some spray, encouraging waves to break early. Daylight tides are high at 08:55 (20.07 ft) and low at 15:21 (4.41 ft). The surf signal builds through the day.

Why show three wave models?
No single wave model is always right. ECMWF is global, not Europe-only, but its published verification reports a long-term lead over other centres for significant wave height and peak-period scores. GFS Wave is a separate global system that forecasts multiple swell components, making it useful for following swell generated by distant Atlantic storms and for an independent comparison with ECMWF.
Around the UK, the 1.5 km UKMO NWS model uses regional bathymetry and coastal masking, refines its grid near coasts and in water shallower than 40 m, and includes bottom friction and depth-induced breaking. This adds shelf-sea detail the global charts do not resolve at the same scale; when the models differ, treat the forecast with more caution.
