Maui Surf Report for September 8th, 2018

2-4 foot 1-3 foot 1-3 foot 4-7 foot As Tropical Storm Norman continues to track north of the state, moderate trade winds turn more north and weaken. A gentle north to north-northeast wind pattern can be expected through the weekend. Winds briefly veer more east Monday before another backing to the north occurs as Hurricane Olivia approaches. Uncertainty increases during the middle of next week as Olivia, which is forecast to weaken to a tropical storm, will be near or over the islands. Monitor Olivia's forecast and advisory packages from the National Hurricane Center at www.hurricanes.gov. The Central Pacific Hurricane Center will assume responsibility for Olivia's forecast and advisory packages later today. The east swell from Norman will continue to subside and shift out of the northeast. The swell will lower from east to west across the state. A High Surf Advisory remains posted for east facing shores of the Big Island, Maui, Molokai, Oahu and Kauai through 6 pm HST today. Winds and seas should remain below the Small Craft advisory threshold through Monday. A low, long period east swell generated by distant Hurricane Olivia will begin to fill in behind the fading Norman swell on Sunday. This swell will continue to build early next week, likely producing warning level surf during mid week. The ...

Maui Surf Report for September 1st, 2018

1-3 foot 1-3 foot 1-3 foot 1-4 foot Trades will trend down into the light to moderate range by the end of the weekend as high pressure shifts eastward over the northeast Pacific and Hurricane Mariam tracks northward far northeast of the marine area. The overnight ASCAT pass, however, did reflect fresh trades holding in place over the marine area, mainly the channels and typically windier locations. Fresh to strong trades are forecast to return Tuesday through midweek. Forecast confidence begins to lower beyond Wednesday due to varying solutions from cycle to cycle for Hurricane Norman as it approaches the region. Surf along east facing shores will remain up through the weekend due to a combination of fading short-period trade wind energy and 10-12 second energy filling in from Hurricane Miriam. This swell will become reinforced early next week as Hurricane Norman approaches the region. Provided Norman will continue westward at a higher latitude, the Big Island shouldn't have as much of an impact on the smaller islands with regard to shadowing. As a result, surf could exceed advisory levels for all east facing shores and potentially near warning levels through the midweek time frame along east facing shores. Surf along south facing shores should come up through the day today as a new ...

Maui Surf Report for August 25th, 2018

1-3 foot 1-4 foot 4-7 foot 4-6 foot Tropical Storm Lane is forecast to make a turn toward the west and pass south of Kauai late Saturday and Saturday night. Heavy precipitation associated with Lane will continue to fall over the coastal waters, through the weekend. Surf will remain elevated along exposed shores through Saturday as Lane begins to move off to the west. Heights along the south shores will likely lower into average range no later than Sunday. East shores will remain elevated beyond Saturday due to expected strong onshore winds filling in as Lane exits. Tide Predictions High tide at Kahului was 1.59 foot at 2:00 PM early this afternoon, dropping to a low of -0.09 foot at 2:00 PM early this afternoon, then rising to a high of 2.55 foot at 2:00 PM early ...

Maui Surf Report for August 23rd, 2018

4-6 foot 4-6++ foot 5-8++ foot 4-6++ foot Hurricane Lane, currently located around 225 nautical miles south of Kailua-Kona, is now tracking toward the northwest around 6 knots and is forecast to pass very close to the leeward waters of the smaller islands Thursday through Saturday. Conditions have already begun to deteriorate over the Big Island and Maui County waters due to a large area of heavy showers and strengthening winds. A similar trend is expected across the Oahu and Kauai waters late tonight through the day Thursday as Lane approaches. Impacts associated with Lane tonight through Saturday will include: hazardous seas, life-threatening surf (warning level; quickly building overnight through Thursday night), beach erosion, overwash onto vulnerable coastal roadways as Lane makes its closest approach, and storm surge (surge guidance estimating ranges from 2 to 5 feet with impacts potentially occurring on all islands) along exposed coasts/harbors. ...

Maui Surf Report for August 20th, 2018

4-6+ foot 2-4+ foot 4-12+ foot 4-6+ foot Marine interests on the Big Island (leeward/southeast coasts) should finalize all preparations for deteriorating conditions by noon Wednesday as Hurricane Lane begins to approach from the south. The earliest potential onset of tropical storm force winds (34 knots or greater) across the waters around South Point and off the coast of Kona will be through the day Wednesday. Once these conditions are realized, it will be too late to prepare. Interests in Maui County and on Oahu should finalize all preparations come Wednesday evening and by noon Thursday for Kauai. The Hurricane Watch currently in place for the waters surrounding Oahu and Maui County will likely become updated to a warning later Wednesday and expanded across the Kauai waters. Impacts associated with Lane through the rest of the week for the islands will include: hazardous seas, life-threatening surf (warning level), beach erosion, overwash onto vulnerable coastal roadways, and storm surge along exposed coasts/harbors of all islands as Lane passes through. Improving conditions are expected by the end of the upcoming weekend as Lane slowly begins to track away from the island waters. ...

Maui Surf Report for August 20th, 2018

1-3++ foot 1-3++ foot 1-3++ foot 1-4++ foot Please note that tropical cyclone operations are in effect. A weak surface trough west of Kauai will move west away from the area today and tonight as high pressure builds to the north. This will result in a gradually increasing trade wind flow through Tuesday. A Small Craft Advisory has been posted for the windier areas around Maui and the Big Island in anticipation of the increasing trade wind flow. As Hurricane Lane moves into an area south of the islands by mid-week, the pressure gradient will likely increase, likely leading to increasing trade winds, and potentially an expansion of the SCA. More significantly, Tropical Storm and/or Hurricane Watches may be required for portions of the southern coastal waters later today. There is significant uncertainty regarding the position and intensity of Lane later in the week, so it is too early to determine what impacts Lane may eventually bring, and mariners need to continue to closely monitor forecasts. Long period east-southeast swells from Hurricane Lane are building at buoy 51004 to the south-east of the Big Island this morning, while the PacIOOS buoy in Hilo is just beginning to detect long-period energy from the east. A High Surf Advisory for east facing shores of Maui and the ...

Maui Surf Report for August 18th, 2018

0-2 foot 0-2 foot 0-2 foot 0-2 foot Light to moderate trade winds are expected to continue today, with winds remaining below Small Craft Advisory thresholds. A weak trough of low pressure will pass through the islands today and tonight, bringing the potential for some heavier showers and thunderstorms. Following the passage of the weak trough, high pressure will build well northeast of the state through the middle of next week, while Hurricane Hector is forecast to pass by to the south of the Big Island on Wednesday. As a result, we should see a strengthening of the pressure gradient across the islands tonight and Sunday, with SCA conditions likely returning to the typically windy waters around Maui and the Big Island. Moderate to strong trade winds are then expected to continue Sunday night through the middle of next week, and SCA conditions may expand to other marine zones. It is still too early to determine the exact impacts that Hurricane Lane may have on the coastal waters, so mariners are urged to keep up to date with the latest forecasts. No significant swells are expected through the weekend, so expect surf to remain small on all shores. A small, north-northwest swell is expected to arrive on Monday and continue through Tuesday. A larger north ...

Maui Surf Report for August 4th, 2018

0-2 foot 0-2 foot 1-3 foot 3-5 foot With strong trade winds continuing, the Small Craft Advisory for all coastal waters has been extended through this afternoon. It has been extended through Sunday afternoon for the typically windy waters near Maui County and the Big Island. The High Surf Advisory for east facing shores was cancelled Friday, but expect choppy surf near advisory levels to continue today. The surf is expected to lower as the winds start to weaken over the next day or so. Small background surf will continue along south facing shores due to small southeast and south swells. A slightly larger long- period south swell is expected to start spreading across the island chain beginning Monday, which may bring surf back to near the summer-time average along south facing shores early next week. The National Hurricane Center is issuing advisories on Hurricane Hector in the East Pacific. The forecast has Hector crossing 140W, into the Central Pacific Hurricane Center's area of responsibility, late Sunday. Depending on the future track and intensity of this system, surf will likely increase along some shorelines around the middle of next week. The surf would likely initially build along south and east facing shores of the Big Island, before spreading to portions of the smaller islands. Stay tuned ...

Maui Surf Report for August 1st, 2018

1-3 foot 0-2 foot 1-3 foot 2-4 foot High pressure north of the islands will maintain strong trade winds through at least Friday. A Small Craft Advisory is in effect for all coastal zones through Friday afternoon, but will likely need to be extended through Saturday due to the persisting strong trade winds. A slight decrease in trade winds is expected on Sunday, but breezy trade winds are expected for the foreseeable future. The elevated trade winds will produce choppy surf along east facing shores, with wave heights increasing through the day today as the winds strengthen. Surf is expected to hold steady through the rest of the week due to the persistent strong trade winds. Small southeast and south swells will maintain small background surf along south facing shores through the week. Small, short-lived west and northwest swells are expected to arrive today, providing a very small bump along exposed north and west facing shores. However, Kauai will help block most of the west swell energy from the other islands. ...

Maui Surf Report for July 29th, 2018

0-2 foot 0-2 foot 0-3 foot 1-3 foot High pressure far north of the islands will maintain moderate to breezy trade winds through the middle of the week. A Small Craft Advisory remains posted through Monday afternoon for the typically windier waters near Maui County and the Big Island. With breezy trades expected to continue beyond that, expect the SCA to be extended. Additional areas may need to be added to the SCA later in the week as the high pressure strengthens. Small, choppy breakers will continue along east facing shores through Monday. An uptick of trade winds during the middle of the week is expected bring an increase in wind swell to east facing shores. Small southeast and south swells will maintain small background surf along south facing shores through the week. Otherwise, no significant swells are expected. ...
