Extended Outlook
No windswell producing high pressure is forecast along the coast until Tuesday (5/22) when north winds and local windswell return and start building in strong holding through late in the workweek. Down south no swell producing fetch is forecast until Wed (5/23). At that time a gale is track under New Zealand producing up to 36 ft seas, but then fading fast before making much headway into the Southwest Pacific. Another stronger but similar system is forecast on Fri (5/25) resulting in 42 ft seas, but again fading fast. Maybe some weak swell to result if one is to believe the models.
