Honolulu is set to experience fairly mild weather, according to the National Weather Service (NWS). Light to moderate trade winds are expected to continue throughout the coming weekend, with a focus on windward slopes and coasts for shower activity. However, the attention shifts to interior and leeward areas early next week as winds diminish and coastline breezes take the main stage. The NWS predicts trade winds will make a comeback mid-week, redirecting shower probabilities back to the windward locales.
The current weather situation, as of the early morning hours, is governed by a 1025 mb high pressure system sitting approximately 1550 miles northeast of Honolulu, while a stationary front hovers about 400 miles north of Kauai. This setup brings light to moderate trades to the Hawaiian archipelago, resulting in partly to mostly cloudy skies and only a smattering of light showers hitting the windward coasts. "Main short term focus revolves around trade wind trends and rain chances during the next few days," the NWS states in their report, indicating a generally stable weather pattern for now.
Things begin to switch up as the weekend winds down, with the forecast pointing to a front dawdling farther north today and then slowly encroaching upon the islands. The winds are expected to lose some of their oomph, paving the way for land and sea breezes to dominate early into next week. A couple of fronts weakening near Kauai could result in a subtle uptick in shower activity, particularly over that island, while the rest of Hawaii seems set to stay on the drier side.
On the aviation front, the light to moderate trades might bring brief periods of showers and low clouds to the windward and higher elevation areas, potentially causing some minor visibility issues. Still, the NWS anticipates predominantly clear flying conditions otherwise, and no advisories have been issued at this time. The marine contexts, too, are finding easterly trades holding on until tomorrow for windier channels, especially around Maui County and the Big Island, but anticipate a lull in the breezy conditions commencing Sunday through the early parts of next week as the frontal boundary meanders closer.
As for surfers, north-facing shores have likely seen their swell peak, maintaining steady under current offshore buoy recordings. "Expect this north swell to hold through the day today, then slowly ease tonight through the weekend," the NWS suggests. Prospects for a new north swell are on the horizon come Monday night through midweek, stirred by northerly winds from a developing low to the north. Meanwhile, south-facing shores will bide their time with minimal activity until a potential pulse from a far-off storm arrives next weekend. East-facing shores, too, stay mellow, lacking the punchy breezes needed to rouse significant surf.
According to the latest forecast from the NWS, residents and visitors to the Hawaiian area can expect the weather to accommodate a variety of outdoor activities over the next several days, with no immediate weather warnings or advisories in place at this time.
