Fading leftovers out of the northwest may still provide surf in the knee-chest high range along select north facing shores today, but it is on the way down and out. Windswell out of the east is on the rise, potentially offering small and sloppy surf around waist-high. Leftover south-southwest swell may also be found at the better exposed south shore breaks. A new south-southwest swell is expected to arrive Saturday that could build to advisory levels at its peak, filling in to offer surf around waist-overhead levels, possibly larger at the best breaks. Yet another similar south-southwest swell is expected to arrive Monday. And finally, another small northwest swell is also expected to arrive Monday evening. The long-range models are hinting toward the development of a tropical system building far east-southeast of the islands around the middle of the upcoming week. Although it’s way too early for any confidence, the models forecast this system could possibly pose a direct threat to the Hawaiian islands next weekend. stay tuned for updates through the week.
Today’s Surf Summary
South facing shores may still offer small surf around 2-4 foot, rising near advisory levels over the second half of the holiday weekend. North and northwest facing shores may offer surf in the 3-5 foot range or slightly higher at the best locations. Upper West shores may see surf around 1-4 foot or possibly better in some areas. Windswell along the east and northeast facing shores may be around 2-4 foot.

Weather Outlook for Friday
Light winds, with land and sea breezes, will continue through Friday with clouds and a few showers over the interior of the islands during the afternoon. Light trade winds will return for the weekend, but will remain light enough for localized land and sea breezes. Expect trade winds to slowly reach back to moderate levels by the middle of next week.
A surface ridge remains over the islands this evening, with light southerly synoptic winds across the area. Clouds developed earlier over the interior sections under daytime heating are on the decline, though some lingering clouds may persist, especially over the Big Island. Air mass in the island vicinity is a little unstable, though the lack of low level moisture is generally keeping precipitation a minimal. But then convection flared up along the Koolau in the past couple of hours, bringing moderate rainfall. These convection will probably continue for a few more hours before dissipating. Satellite imagery also revealed area of low clouds just south of Kauai and Oahu at time. With the southerly synoptic flow, these clouds may reach those islands over night.
The light winds will continue for Friday with widespread areas of land and sea breezes as little change is expected on the overall weather pattern. Clouds and a few showers will develop over the interior and lee areas of the islands during the afternoon and may linger through early part of the evening, with some clearing is expected overnight.
The surface ridge over the islands is finally expected to lift north beginning Saturday, as storm system far north of the state is forecast to move north. This will allow light trade winds will return across the islands.especially over the eastern islands. But then trades will be light enough for localized land and sea breezes to still be somewhat widespread. Low level moisture embedded in the light trade winds will reach the islands. Thus expect a little more clouds and showers over the windward areas, with additional pockets of clouds and showers possibly developing over leeward and interior areas due to light winds.
Stronger trade winds are expected next week as surface ridge stays far north of the islands. Trade wind weather will return, with low clouds and showers affecting mainly windward and mountain areas.
