South-southwesterly swell will continue to slowly decline in energy along our south facing shores, with waist-high surf likely in some areas. Shadowing from Kaho`olawe will keep many breaks flat to small though. A second smaller, long period south swell is expected to arrive late Sunday, bringing below advisory level surf through the middle of the week. Elevated surf along windward facing shores will continue due to short period trade wind swell. These surf heights are expected to remain below advisory levels, potentially breaking around waist-chest high levels at select locations. Locally strong trade winds will continue to affect portions of the typically windier waters around Maui County as per current land-based mesonet data, and a Small Craft Advisory remains in effect for those areas through Saturday afternoon. Winds will increase tonight across the northern half of the state, namely around Kauai and Oahu, as a weak trough rides by. These winds are expected to approach small craft advisory levels, and these areas will need to be closely monitored throughout the next 24 hours.
Low tide at Kahului was 0.6 foot at 12:49 AM just after midnight, rising to a high of 1.1 foot at 5:21 AM early this morning, then dropping to a low of 0.3 foot at 11:00 AM shortly before noon, before once again rising to a high of 2.2 foot at 6:26 PM early this evening
The sunrise was at 05:45 am this morning and will set at 07:11 pm this evening. The Moon is currently 20 days old, and is in a Waning Gibbous phase. The next Last Quarter will occur at 6:20 PM on Monday, June 27th.
Sunset: 7:11 PM
Weather Outlook for Saturday
Strong high pressure far north of Kauai will continue to generate moderate to breezy trade winds into next week. An increase in showers is expected for the smaller islands overnight as an area of enhanced moisture embedded in the trades moves through the state. Drier conditions are expected from midday Saturday through the rest of the weekend, with passing showers favoring windward and mountain areas, and just a few light showers leeward. The Kona slopes of the Big Island will continue to see clouds and widely scattered showers each afternoon and evening.
Showers were quite active across the smaller islands from Maui through Kauai Friday evening, as an area of enhanced moisture embedded in the trade winds moves into the state from the east- northeast. This so-called screaming eagle cloud formation is associated with a weak low level trough. Mimic-TPW satellite imagery also clearly shows this feature, with estimated PW values up to 1.7 inches. A considerably drier airmass lies to the northeast of the screaming eagle feature, with estimated PW values dropping off to around 1 inch north of 24N and east of 155W. Surface analysis depicts strong high pressure far north of the state, driving fresh trades over the islands. The 00Z soundings reflected a drier airmass ahead of the advancing area of moisture, with PW values of 1.1 to 1.2 inches and typical inversion heights between 6500 and 8000 feet.
Rather wet conditions will prevail overnight across windward areas, especially over the smaller islands. Most of the showers will be light to moderate, but rainfall totals could add up to 1 to 2 inches in the wettest spots due to the frequency of the showers. Scattered showers will spill over into many leeward areas of the smaller islands as well. Showers will likely increase overnight across the windward Big Island, but it appears that the bulk of the enhanced moisture will pass north of that island. The existing forecast appears to be on track, and no updates are planned for this evening.
The screaming eagle will move west of the state on Saturday morning, with the drier airmass spreading in from the northeast. This will result in a considerable decrease in shower activity by midday. Breezy and relatively dry trade wind conditions are expected from Saturday afternoon through the remainder of the weekend, as strong high pressure remains anchored far north of the state, with a dry and stable airmass in place over the islands. Passing showers will favor windward and mauka areas, with only a few light showers over leeward areas. The leeward slopes of the Big Island will continue to see their usual diurnal pattern of clearing skies late night and morning, with clouds and widely scattered showers in the afternoons and evenings.
Little change is expected through the early part of next week, with moderate to breezy trades prevailing, along with a typical trade wind shower pattern. A wetter trade wind pattern may develop by midweek, when models develop a mid level trough near or just west of the state, and bring an area of enhanced moisture in from the east.
