The other main large-scale factor in March is the development of a healthy North Pacific High (NPH). Often you can’t count on the NPH to deliver much of a punch in the spring. Yet, every few years the NPH strengthens early. And the early indications are that this year the NPH has been strengthening early. An early strengthening of the NPH tends to bring brisker winds to San Diego. With brisker northwest winds across the southern California bight and the marine layer not yet firmly fixed overhead as it will be in May and June, the San Diego area may just be poised to see afternoon WNW winds reaching 12 to 15 knot winds fairly often. When compared with historical averages in the attached graphs, this should mean winds will reach historical averages or be slightly above average during this year’s NOOD race.
