The subtropical ridge will strengthen north of the islands through Wednesday, increasing trade wind speeds to Small Craft Advisory (SCA) thresholds from Wednesday morning on into the weekend across the windier waters and channels near Maui and the Big Island. A low level trough passing from east to west across Hawaiian Coastal and Offshore waters from Tuesday into Wednesday along with an upper level disturbance will enhance rain shower activity for all waters.
A series of small to moderate, medium to long period south swells will keep surf along south facing shores elevated through the week. A moderate, medium period south swell will slowly fade through Wednesday. The forerunners of the next long period south swell will begin to arrive in the islands by Wednesday morning, and then build into Wednesday night, peaking on Thursday with head high to overhead surf heights at most exposed south shore surf breaks.
Surf along east facing shores will gradually build through Wednesday and then hold into the weekend as trade winds strengthen. West facing shores will remain on the small side with a slight south swell wrap. Surf heights along north facing shores will remain fairly flat due to the lack of significant north swell energy.
None.
