Detailed Forecast

Synopsis

Breezy trades will gradually weaken to moderate speeds by the latter half of the week. Periodic showers will filter in on the trade wind flow, mainly focusing over windward and mauka areas. By next weekend, the background flow may become light enough to support land and sea breeze development.

Short term update

Radar and satellite show scattered showers developing from over and north of Maui County east to over and north of Oahu. Isolated showers were seen over Kauai County and the Big Island. Most of these showers were occurring over windward and mauka areas, but a few were surviving over to leeward areas. Winds were generally out of the northeast at speeds averaging 5 to 15 mph, with a few gusts above 20 mph in the typical windy spots. Scattered showers should continue through the night, mainly windward and mauka, as is typical for a trade wind pattern. This is handled well by the current forecast and no updates are planned at this time.

Prev discussion

Issued at 342 PM HST Sun Jun 7 2026
Radar and visible satellite imagery show isolated to scattered showers moving into windward and mauka areas across the state this afternoon. A surface ridge extending over the region from the northeast continues to supply very stable conditions across the state, with the afternoon upper air soundings at Lihue and Hilo showing strong inversions around 7,000 feet. Based on the upstream cumulus, brief isolated to scattered showers will continue to be ushered into windward and mauka areas under the inversion on the breezy trades through the rest of the afternoon, with an uptick in shower coverage expected overnight into Monday morning.
The surface ridge to the northeast of the state currently driving breezy trades across the area will weaken slightly as it sags south, then get pushed closer to the state through the week as a series of lows move across the northern Pacific and a front approaches the region from the northwest. This will cause the trades to gradually ease through the week. Background winds may become light enough by Friday to support land and sea breeze development, bringing afternoon clouds and showers to leeward and interior areas and partial clearing at night.

Aviation

Moderate to breezy trade winds are expected to continue through Monday before gradually weakening heading into midweek. Showers embedded within the tradewind flow are primarily impacting windward and mountain areas, with limited spillover into leeward areas. Brief MVFR conditions are expected within showers while VFR prevails elsewhere.
No AIRMETs for mountain obscuration this evening, but it is possible that with clouds and showers moving in, it could be issued for any of the islands.
AIRMET Tango is in effect for mechanical turbulence downwind of the mountains due to breezy trade winds, and this is expected to continue through at least Monday.

Marine

Issued at 342 PM HST Sun Jun 7 2026 Surface high pressure will remain anchored far northeast of the islands through early this week. A Small Craft Advisory (SCA), remains in effect for the typical windy waters around Maui and the Big Island. By the middle of this week, a ridge north of the islands associated with the high will be weakened and depressed southward. As a result, trades will drop further and allow the SCA to be cancelled entirely Tuesday or Wednesday. As the ridge shifts further south, it will eventually end up near the Hawaiian Islands by Friday or Saturday, which will bring light and variable winds across the area towards the end of the week.
Small long-period forerunners of the next south swell continue to fill in this afternoon with energy centered in the 18 to 22 second bands along our nearshore buoys. Energy from this swell is expected to peak late Monday into Tuesday and bump up surf to slightly higher than the June average, but still below advisory criteria. Expect this swell to fade through midweek. A smaller pulse of south-southwest swell is due late Thursday and Friday, and a more significant south-southwest swell is on track to arrive next weekend, likely bringing advisory level surf by late Sunday along south facing shores.
The combination of a large south-southwest swell coinciding with the peak monthly tides will lead to significant wave runup across areas of the shore that typically remain dry during the afternoon high tide cycle from June 14th through around June 16th. Coastal flooding is also expected across low-lying coastal roadways, docks, boat ramps and other coastal infrastructure.
Small background energy from the west-northwest is possible over the next several days from a former Typhoon in the West Pacific last week. Rough surf along east-facing shores will remain around seasonal average today, then slowly decline through the midweek as trade winds ease. Surf will drop well below seasonal levels along east facing shores by the end of the week as the trades dissipate.
