Lighter winds are expected Tuesday and Wednesday as a low passes north of the state. Along with the lighter winds, expect a few clouds and showers over the interior parts of the islands during the afternoon and evening hours. As the low moves to the northeast late Wednesday, a ridge will build in to the north of the islands. This will allow trade winds to build back into the region during the second half of the week. By the weekend, more typical trade wind showers will reach the islands on the trade wind flow.
Generally light winds continue across all terminals this evening, expected to persist through the next couple of days. Onshore sea breezes will bring interior clouds and light showers, followed by overnight clearing with emerging offshore land breezes. Expect low-MVFR/IFR due to low cloud ceilings. Otherwise, VFR conditions prevail.
No AIRMETs in effect.
Issued at 345 PM HST Mon Apr 20 2026 A series of lows and troughs northwest and north of the islands will act to keep weak to locally moderate east southeast flow in place across the local waters through early Wednesday. Light wind flow should allow for afternoon sea breeze development near the shores. By Late Wednesday through this weekend, surface high pressure building north of the area will bring a return of moderate to locally strong trades.
Forerunners from a small, medium- period, northwest swell are still on track to arrive late tonight, with this swell forecast to build Tuesday and peak on Wednesday. This should bring an uptick in surf along north facing shores.
A moderate, medium- period north- northeast swell arrives on Tuesday and peaks also on Wednesday, bringing moderate surf to north and northeast facing shores, before slowly declining through the end of the week. East facing shores will see an increase in surf with wrap from the aforementioned north-northeasterly swell despite below- seasonal average trades. Strengthening trades late this week will also give east facing shores a bump in surf.
Surf will continue to be small along south facing shores through the period.
None.
