The National Weather Service says an upper-level low causing increased showers in Honolulu today and tonight, with sunnier conditions expected for the holiday weekend. A high-pressure system is maintaining breezy trade winds through Sunday. The upper-level low may cause isolated thunderstorms, especially near Kauai in the morning, according to the National Weather Service.
Surfers can expect consistent east shore waves from tradewinds and increased south-facing shore swell through the weekend. The National Weather Service reports "moderate to locally strong trade winds through the weekend" caused by a distant high pressure system. Trade winds are forecast to weaken after Memorial Day. A Small Craft Advisory remains in effect for "Maalaea Bay-Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters," where winds create choppy conditions for smaller vessels. Conditions are expected to improve early next week as the high pressure system weakens.
Surfers, locals, and tourists should monitor tides starting on Saturday, as the National Weather Service forecasts a rise in tides that could cause minor coastal flooding during early afternoon high tides. Honolulu can expect more clouds and less rainfall by the end of the week. The National Weather Service states that "while maintaining a dry and stable boundary layer over us," increased clouds will not bring significant rain despite moisture from the jet stream.
