Stay well away from the shoreline today. And please understand that tsunami waves cannot be ridden! A powerful earthquake offshore near Japan sent a tsunami across the Pacific Ocean and first hit Hawai`i around 3:00 am last night. The warnings have been downgraded to advisories, but there may be surges throughout the day. Any surf that is happening around the islands is not worth risking our lives over. Maui has had the largest reported waves, most significantly a near 6 foot surge pushing up to 1/3 of a mile inland in the Kahului area. Please use the Discussion Board at the bottom of this page to report any experiences, photos or videos that you have.

Extended Surf Forecast

Hawaii Swell Height Model
Forecast for March 10th-12th
A series of northwest to north-northwest swells are expected to hit the islands through the forecast period, but the quick and zonal flow won’t allow anything to grow much beyond advisory levels. Currently a gale pushing over the Aleutian Islands is aiming a fetch toward Hawai`i but the majority of the energy will miss the islands leaving us with more of an edge-pass when it arrives Saturday or Sunday. Wave heights should only be expected to rise to head-high levels, but some surf breaks may be able to pull in larger sets if we’re lucky. The models show a quickly building low bombing just south of the Aleutians around 170&degW Saturday. If all goes well, a large northwest to north-northwest swell will develop for a Monday arrival, possibly reaching advisory levels. It is a little early for confidence, so don’t set your hopes too high yet. The models do show another low that could produce more action arriving around Thursday. Get what you can while its here though… Spring is right around the corner.

Hawaii Swell Period Model
A broad low in the South Pacific is sending up what could be a decent early-season south swell arriving next Wednesday. A low began building far south-southeast of New Zealand several days ago and then took a rather abrupt turn to the northeast, setting up a broad fetch aimed just east of Hawai`i. The travel distance is far and the odds are against us, but I think we should pick up at least a moderate south swell out of this that lasts for a few days. The main concern is that the main fetch was pretty far east of New Zealand which will put a lot of French Polynesian islands in the way. We’ll just have to wait to see what we get. The flow should remain aimed in a way that provides us with plenty background swell through the rest of the forecast period and beyond. It’s hard to accept that Winter is drawing to a close.

Wind and Tide Information

The Maui Wind Report for today is: Moderately breezy tradewinds will begin dropping today around 10-20 mph out of the east and some areas may still see slightly stronger gusts this morning. The weekend should be light to moderate out of the east-northeast.

The Maui Tide Report for today is: High tide at Kahului was early this morning, dropping through the morning hours to a low of 0.1 foot at 11:35am just before noon, rising again to a high of 1.6 foot at 8:33pm later this evening. Please be aware that sea heights could fluctuate greatly through the day due to the tsunami… I advise everyone to stay well away from the shores through the day.

Maui Weather

The Maui weather forecast is: mostly sunny conditions with scattered showers possible over windward and mauka areas. High temperatures should be in the 77-82° range under easterly winds of 10-20 mph. High pressure north of the state will weaken today as an upper-level ridge builds to the west resulting in lighter winds and a drier and more stable airmass through the weekend and early next week. As the winds decrease, the direction will swing more to the east and possibly even east-southeast, but vog is not expected to drift over to Maui from the Big Island. Volcanic emissions have risen dramatically since Kilauea’s new vent opened up so hopefully it won’t have too much impact. The models show a strong an broad high pressure system moving into the area early next week that could push down a shearline around the middle of the week, potentially building strong tradewinds that could become very strong. Stay tuned for more details.
