Maui Surf Report for October 18th, 2017

5-7 foot 3-4 foot Flat 4-5 foot Hazardous marine conditions will continue through Friday due to strong- to gale-force trade winds and rough seas. Latest buoy observations around the islands reflect this and are holding within the 8 to 11 ft range. Heights within the 12 to 15 ft range are likely occurring over the windier locations, especially across the Pailolo and Alenuihaha Channels and waters south of the Big Island where the strongest winds are. Satellite altimetry data within the past 12 hrs even showed wave heights up to 14 ft west of Kauai. Small craft advisory headlines will remain likely through Friday over most waters. Gale conditions will likely hold over the Pailolo and Alenuihaha Channels through the day Thursday. The latest guidance lines up well with the current pattern and depicts a weakness within the ridge axis developing north of the islands over the upcoming weekend. This weakness will be in response to a frontal boundary approaching from the northwest and a weak surface trough approaching from the east. Trade winds are forecast to respond and gradually trend down late Saturday through Sunday. Seas will drop below advisory-levels (10 ft) through this time. Surf along east facing shores will remain rough through the rest of the week due to ...

Maui Surf Report for October 14th, 2017

2-5+ foot 2-5 foot 1-4 foot 4-6+ foot Strong to gale-force east-northeasterly trade winds and associated short-period rough seas will dominate the marine forecast for the second half of the weekend and most of next week as strong high pressure will prevail north of the area. The expectation is that winds will increase through Saturday evening, and then remain elevated through at least mid-week as high pressure prevails to the north of the islands. Combined seas at PacIOOS buoys over windward waters have diminished from their rapid spike on Friday, and are running between 7 and 10 feet this morning. So while winds and seas may be below Small Craft Advisory (SCA) criteria today in some of the zones currently covered by the SCA, increasing winds and seas are expected as early as tonight. Open-ocean winds are expected to be build to near 25 kt tomorrow and continue through Thursday. Where the terrain most accelerates the wind (Pailolo and Alenuihaha Channels), a Gale Watch has been issued in anticipation of gale force winds, potentially beginning as early tomorrow. A High Surf Advisory is posted for east facing shores, where rough and elevated short-period surf is expected through at least Wednesday. A long-period south swell arriving this weekend will likely result in high surf along south facing shores by late Sunday, continuing into Monday before gradually diminishing by mid-week. A small long-period north-northwest swell is expected tomorrow ...

Maui Surf Report for October 7th, 2017

5-8+ foot 4-7 foot 2-4 foot 5-8+ foot Winds will be light through the weekend due to a low pressure system moving toward the west-southwest towards the main Hawaiian Islands. The low is forecast to become nearly stationary several hundred miles north of the state by Sunday. Models indicate that the low will weaken early next week which will allow a weak high pressure ridge to rebuild over the northern offshore waters and restore light to moderate trades across the coastal waters some time Monday or Tuesday. A north-northeast swell has been generated by the low, and while the trade wind swell is on the decline, the north-northeast swell will keep surf along east facing shores near advisory levels today. This north-northeast swell is expected to fill in Sunday night. The High Surf Advisory has been extended through Saturday evening, and may need to be extended further depending on this swell. Surf along north facing shores exposed to this swell is expected to remain below advisory levels. The direction of the arriving swell raises some concerns for surges in the Hilo, Kahului, and Haleiwa Harbors but the swell period may be too short with this event to cause significant problems. The current north-northwest swell will trend down into the weekend. Small reinforcing south-southeast and southwest swells will keep surf from going flat along south-facing shores into next week. Tide Predictions High tide at Kahului was 2.5 foot at ...

Maui Surf Report for September 30th, 2017

1-3 foot 0-2 foot 1-3 foot 1-3 foot A northwest swell associated with a developing storm-force low far northwest of the islands is forecast to fill in across local waters late Sunday, peak Monday, then slowly ease into midweek. Guidance supports a peak around 7 to 8 feet at the northwest offshore buoys late Sunday night into Monday morning. However, if this swell comes in higher, surf could near advisory levels for Monday along north facing shores, especially along north and west facing shores of Kauai where the swell is forecast to be slightly larger anyway. Surf along south facing shores will remain small through this weekend with mainly short-period south and southeast swell energy expected. A large area of gale- to storm-force west-southwest winds around 1300 nm south-southeast of New Zealand will send some small southerly energy our way. As this system continues eastward across the south-central Pacific, the area of gale- to storm- force winds is forecast push northward and become oriented more in our direction. This may provide a slight enhancement out of the southeast locally by next weekend. Small and choppy surf will ease along east facing shores as the winds shift out of the south and become light over the weekend. Rough surf along east facing shores may return with stronger trades by Thursday. Tide Predictions Low tide at Kahului was 0.6 foot at 4:36 AM early this morning, rising to a high ...

Maui Surf Report for September 23rd, 2017

1-4 foot 0-2 foot 1-3+ foot 1-4 foot Surf along south facing shores will remain small through early next week, with mainly background southeast and southwest swell energy expected. The next potential long-period pulse out of the southwest from the Tasman Sea is expected by Sunday and could lead to a slight increase in surf. For the extended forecast, strong to gale-force southwest winds associated with a low in the Tasman Sea may lead to another small southwest swell Tuesday through midweek. A small northwest swell will continue into the weekend before easing. Another small reinforcement from that direction is expected to fill in around Sunday night through the middle of next week. Tide Predictions High tide at Kahului was 2.2 foot at 4:13 AM early this morning, dropping to a low of 0.7 foot at 10:13 AM this morning, then rising to a high of 1.8 foot at 3:47 PM early this afternoon, before once again dropping to a low of 0.2 foot at 10:07 PM late this evening The sunrise was at 06:14 am this morning and will set at 06:21 pm this evening. The Moon is currently 3 days old, and is in a Waxing Crescent phase. The next First Quarter will occur at 2:55 AM on Thursday, September 28th.

Winds will increase to SCA threshold across waters around Oahu by tonight. An SCA is now in effect for those waters and may need to be extended by Monday as locally strong trade winds are forecast to last through the coming week. The current small north swell will continue to lower through today. A couple of very small north and northwest swells are possible during the Tuesday through Thursday time period. A small south southwest swell will peak over the weekend then lower gradually early next week. Another small south southwest swell is expected to fill in on Monday, peak on Tuesday, then lower gradually Wednesday and Thursday. Strengthening trade winds will cause an increase in short period choppy surf along east facing shores this weekend and on through the middle of next week.

The latest Waimea buoy observations reflected a mix of small sources out of the north- northeast, north, northwest and west-northwest. The long-period northwest (310 deg) swell will be the source that holds over the weekend (overall downward trend). Surf associated with this swell will remain well below advisory level each day through the weekend. The latest surface analysis showed a gale developing near the Date Line around 40N (around 1500 nm northwest of Hawaii) along a frontal boundary extending from east to west across the northern Pacific. Guidance shows this feature quickly tracking eastward to a position north of the state by Sunday. Strong northerly winds focused toward the islands between this feature and 1026 mb high pressure to its west will be enough to generate a small northerly (340-010 deg) swell that should reach the waters Tuesday, then hold through midweek before slowly trending down through the second half of the week. Surf associated with this source will remain small along north facing shores. Surf ...

A High Surf Advisory remains in effect for the south facing shores through Saturday afternoon. Model output is still depicting a more active pattern evolving across the northern Pacific for the upcoming holiday weekend, in response to Tropical Cyclone Sanvu near Japan and a gale-force low currently near the eastern Aleutians. If these features continue to develop as forecast, a small west-northwest (300°) swell and a larger north-northwest (330-350°) swell remain possible for next week. The king tides will be in full swing during the 3 day Labor Day weekend and Tuesday. The maximum impact will occur during the period of high tide, slated for the afternoon hours. Time of high tide for Maui are as follows... 1:10 pm HST Saturday, 1:35 pm HST Sunday, 2:01 pm HST on Monday, and 2:26 pm on Tuesday. The tides are still running about half a foot higher than normal from last month's king tide. Beach flooding is likely for some beaches through Tuesday, although ...

Maui Surf Report for August 26th, 2017

0-3 foot 0-2 foot 1-4 foot 2-4 foot A combination of moderate to fresh breezes locally and upstream of the islands and a small easterly swell associated with former Kenneth across the eastern Pacific are generating near advisory-level surf along east facing shores. This will likely hold through the day today, then trend down as the trades and swell ease Sunday into early next week. Surf along south facing shores is expected to come up slightly today as a southwest (220 deg) swell from a Tasman source fills in. The buoys south of the islands are depicting this source within the 15 second band (quite small). This source will slowly ease into early next week. A combination of this southwest swell and small reinforcing small southeast (150 deg) swells will keep the surf from going flat early next week. For the extended, a more notable south (180 deg) swell is expected to fill in and impact the south facing shores of the islands Thursday into the upcoming holiday weekend. A recent ASCAT pass showed a large batch of gales focused toward the state several hundred miles east of New Zealand. The most recent altimeter pass within this region of gale-force southerly winds showed seas up to 30 ft. This is lining up well with the latest wave model guidance, which depicts a 3 ft swell at 16-17 sec filling in across the local waters by Friday. ...

The latest observations at buoys 51003/51002/51004 south of the islands continue to reflect this energy, however, have started to depict a downward trend over the past few hours within the 15 and 16 second bands. Surf along south facing shores will correspond and ease through the day Saturday. Looking ahead into next weekend, mainly small background reinforcing pulses out of the south will keep the surf from going flat each day. Surf along east facing shores will remain small through the weekend due to weaker trades locally and upstream of the state. This trend will likely continue into next week. Although confidence remains low this far out, a small long-period east (90°) swell from distant Tropical Storm Kenneth, currently centered over the eastern Pacific, could fill in and impact exposed eastern shores through the middle to latter half of next week. Winds and seas are expected to remain below Small Craft Advisory levels through the weekend as the pressure gradient weakens. An upper low that is expected to drift southwest over the ...
