Historical surf replay
Mount's Bay conditions using shared west Cornwall wind 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.
Porthleven had little to small, weak surf: its SSE waves were angled into the south-west-facing window and had a short 2–6-second period. The mainly easterly, cross-offshore wind should keep it relatively clean; Sevenstones cannot be assessed for this break because exposure and direction are unavailable.

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.
