The National Weather Service has issued a High Surf Advisory in effect through 6pm Sunday evening for Maui’s north and east facing shores due to a rising large north to north-northwest swell. this large swell and strong trades will keep surf heights above advisory levels over north and east facing shores now through Sunday evening and will likely remain elevated from Sunday night through the first half of next week thanks to another smaller northwest swell which is expected to arrive Monday evening. A moderate south-southeast swell is expected to arrive Monday through Wednesday of next week due to an oriented fetch created by a tropical disturbance currently south of the Big Island. Conditions will not be very favorable due to strong local winds.

An exceptionally strong storm is passing under New Zealand this weekend with the potential to send up some significant energy, but its track is fairly zonal. The storm is expected to rapidly track from west to east which limits the fetch aimed in our direction. However, angular spreading should allow some decent energy to be sent our way, arriving around Friday the 9th. Additional activity through the rest of the forecast period may keep our south shores active for quite a while. Two tropical systems near the islands may produce rough short-period swell from the south to southeast over the next few days, but the life cycle of these systems will be very difficult to predict as will any swells produced. All in all, there should be plenty surf to be found throughout the forecast period.

Today’s Surf Summary

North and northwest facing shores should build to levels well overhead around the 8-12++ foot range depending on exposure. Upper West shores may see some action as well in the 4-6+ foot range, possibly much larger at the best locations. Windswell and wrapping northerly swell should be found along east and northeast facing shores around 5-8+ foot as well. South facing shores may have small to moderate surf around 2-4+ foot.

Weather Outlook for Saturday

Breezy and gusty trades will prevail through the next several days as the islands remain between high pressure to the north and two tropical systems to the south. Increasing tropical moisture from the south and a wetter weather pattern will affect the islands during the rest of the weekend with best chances of rain over the eastern half of the state. There is also a slight chance of thunderstorms for the Big Island from later today through Sunday. The western half of the island chain should remain under a trade wind regime with a little more showers tracking through.

Surface analysis and model data show a strong surface high pressure system centered far north of the state while two tropical systems remain to the south of the islands. This synoptic scenario is keeping rather tight pressure gradients across the area through early next week.

The rather benign weather pattern from the past couple of days will gradually deteriorate starting later today and through early next week as tropical depression Seven-C moves closer to the Big Island. Increasing moisture and even a few thunderstorms associated with Seven-C could reach the Big Island this evening. Better chances of rain will reside over the eastern half of the island chain. The forecast will also continue to carry a slight chance of thunderstorms for the Big Island from tonight and through late Sunday, and could be expanded into Maui county as new model data becomes available today.

For Oahu and Kauai, the forecast will closely depend on the outcome of the aforementioned tropical systems, especially Seven-C currently lingering south of the Big Island. At this time it is too early to tell what kind of impacts, if any, these systems will bring to the islands particularly over Maui county and the Big Island. Stay tuned for updates regarding the progress of this rather complicated forecast scenario for the next several days.
