Historical surf replay
Godrevy forecast and wind 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.
There were small, messy waves at Godrevy and Gwithian: the WNW swell was well aligned, but northerly cross-onshore winds made conditions untidy. The model offshore wave height was 1.4–1.9 feet at 9–9.5 seconds; Perranporth’s aligned inshore signal was weaker and shorter-period.

Observed wind at N 11° was cross-onshore 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.
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.
