A breezy and stable trade wind flow will prevail through much of the week as surface high pressure holds north of the state. Pockets of moisture moving in the trades will focus rainfall over windward and mauka areas with showers briefly passing over leeward areas.
Issued at 329 PM HST Mon Nov 2 2026 Earlier windward showers have largely diminished with VFR for area TAF sites. Trade winds remain moderate to strong, which has been quite gusty for some areas. This will continue into the evening, with some areas seeing lesser winds overnight. Expect trades to continue tomorrow with -SHRA/VCSH generally for windward areas. LLWS was added for PHKO, but that should improve later this evening.
AIRMET Sierra is in effect for mountain obscuration for Oahu and Maui, and for the Big Island from Upolu Point to Cape Kumukahi to South Cape, for clouds and showers above 2000 feet.
AIRMET Tango is in effect for moderate turbulence between FL220 and FL350 statewide due to an upper level disturbance. AIRMET Tango is also in effect to cover moderate turbulence downwind of terrain statewide below 8000 feet. SIGMET OSCAR for severe turbulence has been cancelled.
Issued at 329 PM HST Mon Nov 2 2026 Dominant high pressure north of the area will maintain fresh to locally strong trade winds through most of the week and into the weekend with slight day to day fluctuations. A Small Craft Advisory (SCA) is in effect though Tuesday for the combination of winds for most waters and seas above 10 feet for areas exposed to a moderate north- northwest swell. The 10 foot seas will drop off tonight, but the winds will remain, therefore the SCA will likely be extended further into the week.
Surf along north- and west-facing shores will likely remain at High Surf Advisory level conditions through the remainder of the afternoon as the current moderate, north-northwest swell continues to drop today. Offshore buoy data has stopped coming in as of early this morning, so some uncertainty exists regarding when exactly the advisory level surf will drop below thresholds. Therefore the advisory will be allowed to expire at 6pm. Surf will then become small by Wednesday. Another moderate, long period northwest swell arrives Wednesday night and will likely push north and west shore surf back to advisory levels Thursday into Friday. A medium- period swell fills in on Saturday, likely prolonging moderate to large surf action into the weekend.
The current moderate, medium period south swell will continue a gradual decline through Tuesday. South shore surf will be tiny through much of the week with little southerly background energy reaching the islands. East-facing shores will see an increase in trade wind swell as strong northeast winds remain. Surf along east-facing shores will stay big and choppy through much of the week with the trades.
Wind Advisory until 6 AM HST Tuesday for Big Island North-Kohala- Lanai Mauka-Maui Central Valley South-Maui Leeward West-Maui Windward West-South Haleakala.
Small Craft Advisory until 6 PM HST Tuesday for Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters- Kaiwi Channel-Kauai Channel-Kauai Leeward Waters-Kauai Northwest Waters-Kauai Windward Waters-Maalaea Bay-Maui County Leeward Waters-Maui County Windward Waters-Oahu Leeward Waters-Oahu Windward Waters-Pailolo Channel.
