As Honolulu locals look forward to the coming week, the weather forecast signals a continuation of mild conditions with just a hint of change on the horizon. According to the National Weather Service in Honolulu, light east to southeast winds and mostly dry conditions are set to hold steady through early next week, with potential showers skirting windward slopes and coasts at night, and island interiors in the afternoons. However, midweek might mix things up a bit with a cold front that's expected to stir more southerly winds and potentially, an uptick in showers, especially over the western end of the Aloha State.
Currently, Honolulu is sitting under the influence of a high-pressure system parked some 1800 miles to the east-northeast. This system is driving the gentle land breezes across much of the islands and keeping the skies clear to partly cloudy, as identified by infrared satellite. The radar, however, has picked up a few light showers, making their way to the southeastern terrain of Maui and the Big Island—the rest of the state remaining dry for now. A steady pattern looks to be in play with the high-pressure ridge near Kauai maintaining its position, but shifting winds could begin to slowly alter the scene come Wednesday and Thursday. Forecasters are tracking another front that's looking to, somewhat disruptively, ease Honolulu's usual trade winds.
For savvy navigators of the skies, the aviation outlook over Honolulu is uncomplicated, as stated by the National Weather Service. The prevailing light and variable winds bring land breezes overnight along with sea breezes by the day, ensuring that visual flight rules (VFR) will prevail. While some cloud cover and isolated light showers might develop as the sea breezes take hold each afternoon, particularly over the central and leeward areas, no advisories—AIRMETs—are currently expected.
Marine conditions also reflect the calm ambiance offered by the steady high pressure to the northeast. Sailors and water enthusiasts can expect light and variable winds through tonight for Honolulu's western waters, while light to moderate southeast trades breeze through to the east. Yet, as we extend our gaze towards Sunday and the upcoming week, a resurgence of the easterly trade winds is anticipated, before the potential front might put them on pause once more.
Surfers riding the west-northwest swell should savor the current waters, with forecasts predicting a swell increase tonight into Sunday that could prompt a High Surf Advisory or Warning. "Peak surf heights are expected to exceed advisory levels and could potentially reach warning levels along north and west facing shores Sunday," the National Weather Service cautions. Lastly, a northwest swell is forecasted to arrive Tuesday night, promising steady waves through Wednesday. Meanwhile, the south and east shores should maintain small surf conditions for the time being.
