Monday, May 4, 2026 — Trade winds are back on duty in Honolulu, with mostly clear early skies, steady east-northeast breezes and a classic mix of passing showers and sunshine. The daytime high will land near 83°F, with an overnight low around 73°F. Scattered showers are expected through the morning before skies turn partly sunny by midmorning, and most neighborhoods will only see brief, light rain. Gusts could reach about 25 mph along exposed slopes and shorelines.
What To Expect Today
Showers are most likely before 10 a.m., with around a 40% chance of rain and new totals generally under one tenth of an inch. By afternoon, expect partly to mostly sunny conditions with east-northeast winds around 12 to 18 mph. A few isolated showers may pop up again Monday night. There are no watches or warnings in effect for Oʻahu, according to National Weather Service Honolulu.
Winds And Commute
Moderate trade winds this morning will mean gusty stretches on exposed roads, bridges and ridgelines, so cyclists and drivers of high-profile vehicles will want to keep a firm grip on the wheel. Brief downpours could knock down visibility and leave some slick pavement, so it is worth building in a few extra minutes where showers are moving through. The ridge is expected to weaken on Tuesday, May 5, 2026, which will bring lighter winds and a stickier land-and-sea breeze pattern through midweek.
Marine And Surf Outlook
A moderate northwest swell will build tonight and push surf above seasonal averages during the peak tonight and into early Tuesday, leaving exposed shores choppier than usual and currents stronger. That swell should ease late Tuesday into Wednesday, but guidance points to a larger northwest swell approaching near-advisory heights by Thursday, May 7, 2026. Small-craft operators and swimmers should use extra caution at exposed beaches, where rip currents and rougher water will be the main concerns. More details are available from National Weather Service Honolulu.
Bottom line: expect a breezy Monday with quick, light morning showers, calmer and more humid conditions by midweek, and elevated surf rolling in tonight. A light rain layer and a quick check of local forecasts are smart moves if you are headed to the shore.
