Maui Surf Report for January 14th, 2018

15-25++ foot 10-15++ foot 0-3 foot 10-15+ foot The largest northwest (315-325 deg) swell of the season continues to impact the islands this morning. The offshore buoy (51101) northwest of Kauai peaked through the early evening hours Saturday at 23 ft, which is corresponding to peak seas and surf over the exposed waters and beaches this morning over the smaller islands. For the Big Island, a peak around noon is anticipated before a slow downward trend begins later today. Warning-level surf associated with this northwest swell will likely hold through Monday for exposed north and west facing shores, trend down to advisory levels Monday night through Tuesday, then drop below advisory levels through midweek as the swell eases. The latest wave model guidance appears to have backed off on the previously advertised large north-northwest swell filling in by midweek as a reinforcement. Impacts associated with the large surf will include the potential for overwash onto vulnerable roadways (mainly at and around high tides through tonight) and significant beach erosion. Local winds will remain light into tonight, then begin to strengthen through the week as high pressure builds north of the islands. Advisory-level winds will be possible as early as Monday/Tuesday for the windier channel waters east of Molokai, then across all or ...

Maui Surf Report for January 13th, 2018

15-25++ foot 8-12++ foot 0-3 foot 8-12++ foot Long period swell energy has arrived at Buoy 51101 during the past several hours, and the swell height is now rising quickly there, with the buoy reporting 16 feet at 21 seconds as of 3 AM. This is only a few hours behind the timing indicated by the latest Wavewatch guidance. Satellite altimetry passes during Friday evening also showed the significant wave heights remaining on target with Wavewatch guidance. Therefore no significant changes are anticipated from earlier thinking with the incoming northwest swell event. The High Surf Warning remains in place for the north and west facing shores of Niihau, Kauai, Oahu, and Molokai; and north facing shores of Maui and the Big Island. A High Surf Warning for the west facing shores of the Big Island will go into effect this morning. The extra-large northwest swell will build rapidly, bringing surf heights well above warning levels to exposed shores on the smaller islands by this morning, and to the Big Island areas in the afternoon. Warning level surf should be expected to continue through the weekend and possibly into Monday. As the swell subsides, surf should remain at advisory levels into mid- week before another northwest swell arrives Wednesday night. A Small Craft Advisory ...

Maui Surf Report for January 6th, 2018

4-7 foot 1-3 foot 1-3 foot 2-4 foot A new west-northwest swell is arriving in island waters this morning, but latest observations from buoy 51101 (NW of Kauai) indicate swell/wave heights slightly lower than anticipated. The expectation is that the swell will continue to rise to forecast values, and a High Surf Advisory (HSA) is in effect for north and west facing shores of Kauai County. This particular swell direction places Oahu and Maui County in the "swell shadow" of Kauai and Oahu respectively, where increasing surf is expected today, but heights will remain below advisory levels. This swell will bring advisory-level surf to the west facing shores of the Big Island by tonight, and the HSA has been expanded to include these shores. The swell will peak tonight then gradually diminish through Monday. A larger west-northwest swell is expected to arrive Tuesday and continue into Friday, producing advisory-level surf along most north and west facing shores, especially when it becomes increasingly northwest by Thursday. Surf heights may reach warning levels, and the forecast will be fine-tuned as the explosively-developing low tracks across the north Pacific. Latest guidance is suggesting an even larger north-northwest swell arriving next weekend as another powerful low emerges off the coast of Japan. High pressure to the northeast ...

Maui Surf Report for December 30th, 2017

2-4 foot 0-3 foot 0-2 foot 1-4 foot Small northwest swell will continue through Monday, with resulting surf remaining well below advisory levels on north and west facing shores. A larger northwest swell is due to arrive early Tuesday, then peak Tuesday afternoon into Tuesday night, producing surf near advisory levels for north and west facing shores. This swell could also bring combined seas in excess of the small craft advisory criteria of 10 feet for exposed waters. The swell will then decline late Wednesday through Thursday. Short period wind swell and rough surf will continue along east facing shores through the next several days as trade winds persist. Surf along south facing shores is expected to decrease today, then remain at typical very small wintertime levels through the upcoming week. Trades may back off a bit Monday night and Tuesday as a weak front passes across the North Pacific well to the north of the state. SCA winds will probably then return to the windy areas around midweek, when a new high is forecast to build to our north. ...

Maui Surf Report for December 26th, 2017

5-8+ foot 4-6 foot 0-2 foot 4-6 foot Winds over the coastal waters have been veering from the southeast to south as a low northwest of the area tracks to the east. A front associated with the low will begin affecting the islands today through, at least, tonight. The feature will bring widespread showers and periods of thunderstorms to much of the area, which may include lightning, low visibilities, and strong and gusty winds. A reinforcing north-northwest swell has begun turning more northerly. Surf along east facing shores with a more northern exposure will likely see elevated surf for the smaller islands, and later this morning for the Big Island. A High Surf Advisory (HSA) is posted for east facing shores of Kauai, Oahu, Maui, Molokai, and the Big Island through this afternoon. The low mentioned above is forecast to move to a position north of the state around Wednesday. Model runs have backed off a bit on the strength of the winds in the fetch directed at the islands. Thus, surf is now expected to stay just below HSA criteria for north facing shores. A HSA for the exposed east facing shores would become more likely. The swell, however, is highly dependent on the position and strength of the low. Most south ...

Maui Surf Report for December 23rd, 2017

4-6+ foot 2-4+ foot 1-3 foot 0-1 foot An incoming north-northwest swell has shown signs of reaching Buoy 51101 to the northwest of the islands overnight. Expect this swell to increase over the next few hours, and will likely reach Kauai by this afternoon. A High Surf Advisory has been posted for the north and west shores of Kauai and Niihau, and the north facing shores of Oahu, Molokai, Maui and the Big Island. Advisory level surf will likely reach the central islands late today or this evening. The Big Island shores will likely reach advisory levels tonight. Expecting the swell to peak tonight and then begin to subside tomorrow. The Small Craft Advisory remains posted for waters around Maui County and the Big Island due to the strong winds. Winds are expected to veer from a north to northeast direction to a more typical trade wind direction today, and drop below SCA levels later today. Seas associated with this swell will bring SCA conditions to the waters as early as midday today to the northern waters, and spread down the island chain into the evening hours. Overnight Saturday, seas will begin drop below 10 feet over the northern waters, but will linger above 10 feet for the southern half through Sunday. ...

Maui Surf Report for December 15th, 2017

6-10 foot 4-6 foot 0-2 foot 2-4+ foot Northwest swell continues to slowly decline at the nearshore PacIOOS buoys, but has dropped off quickly during the past several hours at offshore Buoy 51101. The High Surf Advisory for north and west facing shores has been dropped as surf on those shores will continue to gradually decline today. Strong northeast winds are expected to produce advisory level surf on east facing shores today and tonight, and we have issued a High Surf Advisory for those areas. These winds will drop off quickly late tonight and Saturday, but the residual swell will cause surf along east facing shores to subside more slowly. Strong northeast winds will continue across much of the area today, and combined with the lingering swell will produce Small Craft Advisory conditions across most zones. The SCA was previously extended for most of the area through this afternoon. We have now replaced the previous Gale Warning with a SCA for the Alenuihaha Channel as well. Winds and seas will gradually subside this afternoon and tonight into the weekend, with conditions expected to be below SCA criteria for all waters Saturday through Monday. Heavy showers and isolated thunderstorms will be possible across parts of the coastal waters today through at least Saturday due to a ...

Maui Surf Report for December 13th, 2017

15-25+ foot 7-10++ foot 0-3 foot 1-4++ foot A High Surf Warning is in effect for north and west facing shores of most islands with a High Surf Advisory for north facing shores of the Big Island of Hawaii. A very large north northwest swell is peaking this morning, but remain quite large on Thursday, then subside through Saturday. North winds are spreading over the Hawaiian coastal waters behind a dissipating front. For now, wind speeds are below the 25 knot Small Craft Advisory threshold, but a SCA is in effect for most waters due to large seas associated with the north northwest swell. Winds will strengthen over the next 36 hours as high pressure builds northwest of the area and a trough forms to the east. Winds will reach SCA levels in the windier areas around the Big Island and Maui County today strengthening to near-gale force on Thursday. Winds will subside Friday into Saturday as the trough approaches from the east. The approaching trough will bring increasing moisture and instability, so thunderstorms will be possible as early as Thursday night. ...

Maui Surf Report for December 11th, 2017

8-12 foot 6-10 foot 0-3 foot 4-6 foot The current north-northwest swell peaked across the coastal waters during the afternoon and early evening hours on Monday, and has been slowly declining overnight. Upstream buoys and wave guidance show that this decline will continue today. The high surf warning has been dropped and replaced by a high surf advisory for north and west facing shores of the smaller islands, while the high surf advisory continues for the north facing shores of the Big Island. Expect surf to drop below advisory levels by late this afternoon. This swell continues to produce seas at or above 10 feet across some windward waters, and the Small Craft Advisory has been extended through today for the Maui County and Big Island windward zones. Seas should drop below 10 feet in those areas during the afternoon. The next north-northwest swell is expected to arrive Tuesday, then peak Tuesday night into Wednesday. This swell is forecast to be even larger than the current swell, and is expected to produce warning- level surf on north and west facing shores of the smaller islands. Surf on the north facing shores of the Big Island will probably reach advisory levels in some areas, but with a lot of local variations due to the expected ...
