Honolulu started Thursday, April 2, 2026, under mostly cloudy skies and a steady trade wind machine, with early morning temperatures in the upper 60s and afternoon highs expected to top out near 79°F. Isolated rain showers are favoring windward and mauka neighborhoods, especially overnight and into the early morning, while most leeward spots stay on the dry side. East‑northeast winds are noticeable across town, keeping east‑facing waters choppy and giving travelers one more thing to factor in when planning around gusts.
Afternoon Winds Pick Up
By this afternoon, east‑northeast winds are expected to run about 12 to 16 mph with gusts up to 22 mph, which can make steering high‑profile vehicles a little dicey on exposed roadways. Brief showers could knock visibility down in a hurry, although, according to the National Weather Service, most daytime hours should still be mostly sunny with only about a 20% chance of showers. The trade winds, however, are not going anywhere.
Showers And The Week Ahead
Through the weekend, expect hit‑or‑miss showers, with rain chances generally in the 20 to 30% range and new rainfall amounts usually staying under a tenth of an inch. Forecast discussions and model guidance point to a wetter pattern settling in by early next week. Forecasters caution that scattered to numerous showers and locally heavy downpours are possible by the middle to latter part of next week, which could bring localized flooding concerns. For context on the recent setup, see our earlier look at blustery trades and hit‑or‑miss showers.
Marine And Surf Impacts
A Small Craft Advisory is in effect for the typically windier waters, including Maalaea Bay, the Pailolo and Alenuihaha Channels, and Big Island leeward and southeast waters, until 6 AM HST Friday, April 3, 2026. Small boats are urged to avoid exposed launches and stick to more sheltered harbors. East‑shore surf will gradually ease today, but choppy, short and steep waves will linger. For the latest zone‑by‑zone warnings and harbor feeds, check the National Weather Service.
Bottom Line
A light rain jacket will come in handy for morning errands, and it is a good day to secure loose outdoor furniture before the gusts do it for you. Small‑boat outings are better saved for after the advisory expires. Conditions look to stay breezy through the weekend and could turn noticeably wetter by the middle of next week, so keep an eye on updated forecasts from the National Weather Service before heading out.
