Vog to move up island chain due to E/SE winds
HONOLULU (KHON2) – A rather stable, light to moderate trade wind flow remains in place this afternoon. A surface trough lies between Hawaii and somewhat strong high pressure farther north, causing the local pressure gradient and resulting trade winds to weaker than usual, and a mid-level ridge sitting over the islands is maintaining stable conditions with an inversion based near 7,000 ft. A narrow slot of reduced moisture is producing minimal rainfall along windward areas this afternoon, and aside from scattered showers over the Kona slopes of the Big Island and Ulupalakua area of Upcountry Maui, leeward areas are dry. Shower activity over leeward Maui will dissipate quickly around sundown and will diminish overnight on the Big Island. Shower activity over windward areas will remain light, with the exception of a possible uptick near Kauai and Oahu near sunrise. Subtle changes are expected Monday and Tuesday. A surface trough will develop roughly 600 miles northwest of Kauai and cause local trade winds to veer out of the east to east-southeast, possibly causing afternoon leeward sea breezes to be more extensive on Kauai and Oahu. The inversion will weaken over these islands as well, suggesting higher chances for afternoon showers over leeward terrain. Copyright 2025 Nexstar Media, Inc. All rights reserved.

High Surf Advisory for south shores
HONOLULU (KHON2) – A stable, light to moderate trade wind flow will continue through Sunday. The trades will remain down from the past few days as the pressure gradient south of broad North Pacific surface high pressure stays relaxed due to a front far north of Hawaii. Aside from areas of thin high clouds, an upper-level trough parked over the region will have little effect. Diffuse bands of moisture moving along the trade wind flow will focus modest rainfall along windward slopes, and a band passing through late tonight and Sunday will mainly affect Kauai and Oahu. Aside from afternoon showers on the Big Island and Kauai, leeward areas should remain rather dry. Subtle changes are expected Monday and Tuesday. The above mentioned upper-level trough will deepen west of the state and induce a surface trough several hundred miles northwest of Kauai. The current south southwest (200 degree) swell will bring large breaking surf to all south facing shores through the day Sunday, then gradually decline early next week. A High Surf Advisory is in effect for south facing shores through 6 PM HST Sunday. No other significant south swell sources expected through the remainder of next week.

Trade winds to weaken by Memorial Day
HONOLULU (KHON2) – At the surface, a strong high to the far northwest of the state and a weaker high to the far east-northeast are separated by a northeast-to-southwest oriented front heading eastward towards the West Coast of the mainland. This pair of highs will continue to bring moderate to locally breezy trade winds to the island chain through this weekend. As a broad low develops to the distant northeast early next week, it will weaken the high to the northwest, relax the local pressure gradient, and bring lighter trade winds to the area. This weaker flow will persist through much of next week and may allow for sea breeze development across some leeward areas, increasing clouds and bringing a slight chance of rain. Looking aloft, the upper level low that's been responsible for enhancing tradewind showers over the last day or two will gradually push eastward and away from the state over the next couple of days, with mid level ridging building overhead in its wake. A weak upper level trough/low will develop near the northwestern end of the state midweek, and sweep across the state on Wednesday. While this feature will introduce some instability aloft, moisture will still be limited, so not expecting it to cause much of an uptick in showers at this time. A strong mid level ridge will quickly build overhead in its wake, bringing more dry and stable conditions through the rest of the week. Small Craft Advisory until 6 PM HST Sunday for Maalaea Bay, Pailolo Channel, Alenuihaha Channel, Big Island Leeward Waters, Big Island Southeast Waters. Copyright 2025 Nexstar Media, Inc.

Trade winds to persist into next weekend
HONOLULU (KHON2) – High pressure far northeast of Hawaii will drive breezy trade winds through the next week, with slight variations through the week. Cumulus clouds and scattered showers will move across the state pushed along by the trades, focusing mostly over windward and mauka sides of the islands. Isolated showers will pass over leeward areas of the smaller islands at times, but will not linger long. Most showers will fall during the overnight and early morning time frames, except for Big Island which will receive most of the showers during the afternoon. Overall rainfall amounts will be insignificant through midweek. An upper low moving across the state could increase shower coverage and intensity Thursday through next weekend, with a similar distribution across mostly the windward and mauka areas. Small Craft Advisory until 6 PM HST Monday for Kauai Northwest Waters, Kauai Leeward Waters, Kauai Channel, Oahu Windward Waters, Oahu Leeward Waters, Kaiwi Channel, Maui County Windward Waters, Maui County Leeward Waters, Maalaea Bay, Pailolo Channel, Alenuihaha Channel, Big Island Leeward Waters, Big Island Southeast Waters.

Small Craft Advisory in effect as trade winds strengthen a bit
HONOLULU (KHON2) – High pressure north of the islands continues to produce moderate to breezy easterly trade winds across the state. Satellite imagery shows partly to mostly cloudy skies across the region this afternoon, with the typical distribution of clouds over windward and mauka areas and the Kona slopes of the Big Island. Radar imagery shows generally dry conditions with isolated to widely scattered showers embedded in the trade wind flow moving into windward coasts and slopes, along with a few showers over leeward slopes of the Big Island. Guidance continues to show high pressure strengthening as it moves northeastward and further away from the islands tonight through early next week. This will maintain breezy trades across the islands. The trades may ease slightly during the middle to latter part of next week as a couple of fronts pass by to the north of the state. Fairly typical trade wind weather will prevail through most of the forecast period, with showers favoring windward and mauka areas, particularly at night and during the early morning hours. A few showers will occasionally spill into leeward areas due to the strength of the trades, and some leeward shower development is expected each afternoon on the Big Island. A disturbance aloft could increase shower coverage and intensity across the islands late next week. Small Craft Advisory until 6 PM HST Sunday for Kauai Northwest Waters, Kauai Leeward Waters, Kauai Channel, Oahu Windward Waters, Oahu Leeward Waters, Kaiwi Channel, Maui County Windward Waters, Maui County Leeward Waters, Maalaea Bay, Pailolo Channel, Alenuihaha Channel, Big Island Leeward Waters, Big Island Southeast Waters.
