Fausto has been downgraded to a post tropical remnant low and will continue to pass Hawaii to the north resulting in light winds and muggy conditions. Trades will quickly fill in tonight through early need week.
Issued at 924 AM HST Wed Jul 29 2026 Winds will be variable today as the remnant circulation of former TC Fausto passes a couple hundred miles north of the islands. Decreasing northerly winds are still pushing MVFR ceilings onto northern and windward slopes from Maui to Kauai, where AIRMET Sierra is in place for mountain obscuration. The AIRMET will likely be dropped for at least Maui and Molokai as the day progresses. Expect widespread sea breezes to produce isolated heavy showers and areas of MVFR ceilings over all islands today. Trades return tomorrow.
Issued at 924 AM HST Wed Jul 29 2026 Variable to light northerly winds today in response to Post- Tropical Cyclone Fausto passing north of the islands. Trades gradually build from east to west in its wake. Moderate to fresh ESE trades become strong Friday through the weekend, eventually warranting a Small Craft Advisory for winds, potentially as early as tomorrow for the windier waters of Maui County and the Big Island.
Nearshore PacIOOS buoys indicate a rapid decline in swell energy from the weakening Post Tropical Cyclone Fausto along E facing shores. The High Surf Advisory remains in effect through this afternoon with the expectation that surf will gradually fall below the advisory threshold during the next several hours. A small bump in short to medium period NE and N will arrive as Post-Trop Cyclone Fausto advances westward north of the islands providing small surf along N facing shores. Flat to tiny surf then returns by Thursday. Surf along E shores will trend up Friday into the weekend due to a combination of building short period trade wind swell and renewed medium to long period E swell, this time emanating from Hurricane Genevieve in the E Pac.
A medium period S swell building today and tonight will push S shore surf toward the summer average (5-6ft) for Thursday. Surf then fades gradually through the weekend while a mix of small S swells maintains surf slightly below the seasonal average.
None.
