Honolulu woke up sticky and gray on Monday, June 1, 2026, with muggy, mostly cloudy skies and scattered showers slipping through windward and mauka neighborhoods. Overnight lows hovered near 73°F and afternoon highs are expected to land around 84°F. Most of the passing showers should be brief and on the lighter side. East-northeast breezes will keep windward slopes on the damp side while leeward beaches are in line for more sunshine breaks.
Scattered Showers Through Midweek
Scattered rain showers are forecast to stick around Monday and into Tuesday, with steadier action setting up over the eastern islands first and then working up the chain on Tuesday. New rainfall amounts are expected to stay mostly under a tenth of an inch. Low clouds and reduced visibility are possible above roughly 2,000 feet, so higher roads and trails may turn foggy and wet. These details come from the National Weather Service in Honolulu.
Breezy Trades Return Late Week
Moderate east-northeast trade winds will ease up early this week, which will allow local land and sea breezes to develop Monday and Tuesday. Trades are forecast to return and strengthen late Wednesday into the latter half of the week. Expect daytime winds of about 7 to 16 mph early in the week with gusts near 18 to 23 mph, then a bump into the 20s on exposed ridges and channels by mid to late week. Keep an eye on those gusts if you have errands on hilltop roads or plan to be on exposed trails.
Surf And Marine Concerns
A series of south to south-southwest swells will keep south-facing shores elevated. Advisory-level surf is likely tonight into Tuesday and could approach or briefly top high surf warning thresholds, around 15-foot faces, by Wednesday on exposed south shores. Small craft advisory conditions are likely to develop Tuesday in the windier channels around Maui County and the Big Island, which will make small-boat travel and channel crossings choppy. For current buoy and surf data see PacIOOS and local forecasts.
Plan Ahead
Carry a light rain jacket for those quick passing showers and be ready for slick spots on windward roads after heavier bursts. Inland and mauka commutes will feel the most impact Monday and Tuesday. If you are boating or planning ocean activities, check advisories and think about postponing small-boat trips Tuesday and Wednesday when conditions look rough. Stay tuned to official updates from the National Weather Service and county civil defense channels for any short-notice changes.
