Historical surf replay
Mount's Bay conditions using shared west Cornwall weather forecasts and observations, Porthleven inshore readings, and offshore signals from Sevenstones and Brittany in the Bay of Biscay. 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.
A summary is not available because this surf day's forecast and observations are incomplete.

These sources describe different locations and exposures. Offshore and inshore buoy readings provide context for Mount's Bay; they are not measurements taken at the surf break itself. Directional labels use Porthleven as a representative south-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 Mount's Bay. The detailed table following the charts contains the same values in text form.
