Honolulu's weather is expected to experience several changes in the coming days. As the remnants of a dissipated front move northward away from Hawaii, the islands will see a brief period of stability, with light to moderate easterly trade winds beginning today and continuing through Sunday. However, a new cold front is forecast to approach Kauai, bringing the possibility of heavier showers and thunderstorms, especially affecting Kauai and Oahu, before typical trade wind showers return next week, according to the National Weather Service.
Current satellite imagery shows that the clouds associated with the dissipated cold front are moving northward, adding a few patches of white to the clear skies over Kauai. The short-range forecast indicates a period of stable trade winds for the region, providing a brief calm for those on the islands. Another cold front is expected to approach from the northwest by Sunday, "producing deeper clouds and showers near Kauai and Oahu on Sunday ahead of the front," leading to chances of localized flash flooding, the NWS warns.
The aviation outlook remains mostly clear, with light to moderate E/SE trade winds supporting widespread VFR (Visual Flight Rules) conditions across Hawaii. However, some areas of the Big Island may experience MVFR (Marginal VFR) due to increased moisture, which could lead to occasional clouds and showers throughout today. A cold front is expected on Sunday, with wind patterns shifting to a southerly direction and bringing clouds and precipitation to the western half of the islands.
The marine report indicates busier conditions for sailors and beachgoers, noting the strong high pressure over the Northeast Pacific. It highlights the current large, medium-period, west-northwest swell, which is at its peak before gradually declining. Ahead of the swell's decline, an advisory is in effect, warning of significant waves hitting the north and west shores of several islands, providing good conditions for surfers. Both Hanalei and Waimea buoys report that the swell is tracking close to model guidance, according to the National Weather Service. A Small Craft Advisory is also in effect across Maui County and selected channels, alerting mariners to rough seas caused by the incoming northwest swell.
Residents and visitors are encouraged to stay informed of the latest updates and advisories through the NWS website.
