Sun and Sand in February
The Sun Strides North in February, swinging higher across the sky each successive day. Already quite noticeable is the change in the time of sunset, currently almost a minute later per day, and sunrise, currently almost a minute earlier per day.
Big Ocean Swells and wild surf conditions occurring during San Diego's winter season can leave certain area beaches partially or wholly denuded of sand. The powerful waves pull sand off the beach and move it into deeper waters offshore, leaving behind deposits of rounded cobbles where sand has been removed. During spring and summer gentle wave action returns much of the sand, usually in time for the arrival of summer tourists. Artificial sand-replenishment projects are usually in the works, too, whereby sand dredged from waters offshore is transported back to the shoreline.
