Despite a decent 6ft plus swell, the SST at Sevenstones off Land's End
is staying 60f ( www.ndbc.noaa.gov/station_page.php?station=62107 ),
suggesting the sea has warmed to a reasonable depth.

With very light winds forecast for Friday, a forecast swell of 6ft, the
surf along the north Cornwall coast could be good & clean.

Still only 8.1mm of rain so far this month.
