St Ives Bay surf conditions on Sun, Sep 6, 2026

Godrevy wave and weather forecasts and weather observations, with Sevenstones offshore and Perranporth inshore wave readings. Each source keeps its own location and role so the view provides coastal context without presenting nearby buoy readings as measurements at the surf break.

Surf Day Summary

AI-generated summary. Hog Says

There were small to moderate, generally clean waves at Godrevy and Gwithian: the west swell was well aligned, with moderate energy and a 9.1-second peak period. Cross-offshore southerly winds helped keep conditions clean, while observations broadly confirmed the modelled swell.

How the stored wind forecast compared

Observed average wind was 1 mph lighter than the last stored forecast.

Forecast: wind mostly southerly; observed: wind mostly southerly.

Observed wind at S 169° was cross-offshore for Godrevy and Gwithian.

These sources describe different locations and exposures. Offshore and inshore buoy readings provide context for St Ives Bay; they are not measurements taken at the surf break itself. Directional labels use Godrevy and Gwithian as a representative north-west-facing swell window; individual peaks and beaches can differ.

Hour-by-hour replay

The charts share the same time axis so offshore signals, inshore readings and regional wind can be compared without treating them as the same measurement location.

Two line charts show wave height and wind speed through the selected day for St Ives Bay. The detailed table following the charts contains the same values in text form.

St. Ives high/low predictions show stored UK local times in the hour they occur. Hourly heights marked ≈ are smooth estimates between those events, not official hourly predictions or observed water levels. Event values marked ≈ have approximate or unspecified source precision. A dash means no event or no supported estimate.
