Spring and Fall, NW to N Spring means March to June, Fall is September to end of October, though it can work through the winter as well.
Summer usually finds it fogged out.
July and August just don't work at this site. The site was pioneered by hang gliders over 20 years ago. Paragliders found it in the early 1990's. This 150 foot near-vertical bluff is an very good hang gliding site, providing your cliff launches are satisfactory. This site is at the end of a drivable paved road, is owned by the County as a county park, as is the beach below.
