High pressure is fading some as it continues ridging into the US West Coast forming the usual pressure gradient over Cape Mendocino CA and generating north winds at 25 kts resulting in local north and generally short period windswell. Low pressure to move into the Pacific Northwest Wed/Thurs dampening the windswell and producing up to 40 kt northwest wind and 18 ft seas possibly adding a little more period to the windswell for late Thurs/Fri. But then high pressure is to return with a vengeance for Friday with 30-35 kt north winds forecast over Cape Mendocino and windswell on the increase again and holding steady well into next week. A small cut-off gale formed just east of New Zealand Wed-Sun (6/21) with 35-40 kt south winds and 26-28 ft seas, offering decent odds for small swell for Hawaii starting late Tues (6/23) but likely not much for the US mainland. A gale formed just off the Ross Ice Shelf and west of Southern Chile on Tues (6/16) with 36 ft seas. Very south angled sideband swell expected into SCal and exposed breaks in NCal by late Wed (6/24). Longer term a weak gale is forecast under New Zealand Wed (6/24) with 28-30 ft seas and tracking east while being reinforced with more wind energy building seas gradually to the 36-38 ft on Sat PM (6/27) and holding into Monday but mostly shadowed for CA by Tahiti and aimed a bit east relative to Hawaii. Still there is some form of consistent swell producing energy in the forecast for the Southern Hemi for foreseeable future providing some thing to monitor. |
