Chartering in Spain
We sailed off the South Coast of France a few years ago around July time frame. We''ve never sailed in US water though, hence can''t offer a comparison. Our experience weather wise was classic long sunny days, but most afternoons the weather blew up to a good breeze - c. F4 - 5 I''d guess.
Sea state was never rough, and we never experienced breaking waves. Gut feel, the water is not as clear as you experienced in the BVI.
Our impressions of the coastline were such that the further you went down the Spanish coast from France the most interesting it became. Much of the French coast is relatively uninspiring, however, c. 20 miles NOrth of Spain this seems to change. Certainly it''s an area we''ve highlighted to sail in next season (when we move our boat to France from the UK).
