After a Max of 19.6C yesterday, and a chilly minimum of 8.8C last
night, todays max has been held down slightly at 18.8C, as yesterdays
near calm conditions have been replaced by a Force 3 onshore SE. Also
yesterday's glassy sea conditions in the bay, have been replace by
rather choppy conditions, with a few white horses.

Swells back www.sennen-cove.com/todaysurf.htm . Wave period supposed
to be 9-10secs, but it seems a long wavelength for that. Good clean
surfing conditions on north & west facing beaches with an offshore
breeze.


Latest numerical wave model analysis for the area shows two swells. One
of abut 2.5 feet from 270 deg with a period of 9 sec and a second one
of about 1.5 feet from 300 deg with a period of 11 sec. That may not
match reality :-)
