SAN DIEGO -- Very high tides are predicted for the Southern California coast, but offshore winds and small waves will lessen the possibility of destructive tidal flooding, the National Weather Service said.

High tides of as much as 7.6 feet above the mean tide are predicted each morning for the next four days. But waves are predicted to be less than three feet high, which by Pacific coast winter standards is practically flat.

The full moon and relative position of the earth means the natural pull on the ocean is at its highest levels this week, and will culminate in a 7.6 foot high tide at 7:43 a.m. Sunday.

Tides at that level sometimes back up storm drains at low-lying locations like Mission Beach.
