Surf Outlook for Saturday, June 8th 2019

South Shores:
2 to 4 feet through Sunday
East Shores:
1 to 3 feet through Sunday
North Shores:
2 feet or less today, rising to 2 to 5 feet Sunday
West Shores:
1 to 3 feet through Sunday

A surface ridge will remain nearly stationary north of Kauai through the weekend. Light to moderate east to southeast winds will prevail, with the lightest winds over Kauai and Oahu waters. Winds will strengthen by Tuesday into Wednesday.

Surf is expected to remain below advisory level along all shores through the middle part of next week. Small surf will continue along south facing shores, with a slight bump possible from a southwest swell through today. A more significant south-southwest swell is possible by the end of next week. A couple of small northwest swells could provide a bump in surf along north and west facing shores through Wednesday. Surf along east facing shores will trend down slightly over the next couple of days as trade winds ease.

Weather Outlook for Saturday, 8th June 2019

Summary

Light to moderate trade winds will prevail into early next week, with stronger trade winds developing Tuesday and Wednesday. Trade winds will bring periods of clouds and showers to windward areas, mainly during nights and mornings. Afternoon sea breezes will bring some clouds and a few showers to leeward areas that will linger into the evening hours, but a stable atmosphere will limit shower coverage and intensity statewide.

Detailed Discussion

There is little or no change in forecast philosophy from last evening. Light to moderate trade winds will prevail into early next week as a nearly stationary surface ridge remains a few hundred miles north of Kauai. East to east-southeast winds will be lighter over Kauai and Oahu versus the moderate east winds expected near Maui and the Big Island. Lighter winds will allow land and sea breezes to develop over many leeward areas, while most windward areas will see a light but steady trade wind flow. An increase in trade wind speeds is expected Tuesday and Wednesday as the ridge moves north and strengthens.

A weak upper ridge is expected to develop over the islands today through Sunday, then and linger into the middle of next week, keeping our airmass strongly capped. No organized moisture sources are expected, so windward showers delivered by the trades should be brief, favoring nights and mornings. Trade winds will be sufficiently light to allow afternoon sea breezes to develop over leeward areas, with the associated convergence leading to some cloudiness (and potentially a few showers) that will likely linger into the evening hours. Models indicate upper troughing will develop near the islands toward the end of next week. This may destabilize our airmass a bit and lead to an increase in trade wind showers.
