Honolulu is rolling into the long holiday weekend with a classic trade-wind mix: breezy conditions, quick-hitting showers and warm, muggy afternoons in the mid‑80s. On Friday, July 3, 2026, scattered morning rain targets windward and mauka spots before skies turn partly sunny later in the day, and overnight lows hover near 75°F. East‑northeast winds stay brisk, generally 14–20 mph with gusts into the upper 20s, so it will feel blustery along east-facing shores and exposed ridgelines. Keep an umbrella within reach for those passing showers and factor in a little extra time if you are driving or commuting in the wind.
Afternoon Winds Crank Up
Moderate to locally breezy trades hold steady through the holiday weekend, with east‑northeast winds commonly 14–20 mph and gusts topping out around 28–29 mph. Leeward neighborhoods dry out a bit in the afternoons, with relative humidity dipping into the mid‑to‑upper 40s, while windward and mauka areas continue to see passing showers riding in on the trades. The setup is tied to a persistent high‑pressure ridge sitting north of the islands, according to NWS Honolulu.
Choppy Seas And Surf On The Rise
A Small Craft Advisory is in effect around the usual windy channels near Maui County and parts of the Big Island, with northeasterly winds of 15–25 kt (about 17–29 mph), gusts to 30 kt (around 35 mph) and seas running 4–6 feet, conditions that can be hazardous for small or open boats. A small, long‑period south to south‑southwest swell builds in on Saturday and could nudge surf to near High Surf Advisory levels on Sunday and Monday, while east-facing shores stay rough and choppy through the period. Mariners and beachgoers should give breaking waves extra room and check the latest updates from NWS Honolulu before heading out.
Holiday Plans: Windward Wet, Leeward Fair
On Independence Day, Saturday, July 4, 2026, look for morning showers and partly sunny afternoons with a high near 85°F. Gusty trades could make things tricky for waterfront gatherings and open-air events, especially along windward shores. If you are heading to windward communities, leave a little earlier and be ready for brief showers, and if you are on the water, play it conservative and follow local marine advisories.
