Monday, June 22, 2026: Honolulu kicks off the week warm and partly cloudy, with a high near 86°F. East-northeast trade winds start off on the lighter side in the morning, then ramp up into the 6–17 mph range by afternoon, with gusts peaking around 24 mph.
Afternoon Winds Crank Up
Through the midday and afternoon hours, those trades strengthen into steady easterly breezes around 13–17 mph, with frequent gusts into the mid-20s. Exposed shorelines and ridge tops will feel it first and most, so expect umbrellas, beach tents, and any loose gear to be more of a handful than the thermometer alone might suggest.
Showers Increasing Tuesday Into Midweek
A surface trough sliding in from the east will bring in more moisture on Tuesday, June 23, 2026, while an upper-level disturbance helps nudge shower chances higher into Wednesday, June 24, 2026. Forecast guidance puts daytime shower odds near 30% on Tuesday, climbing to around 50% Tuesday night into Wednesday, especially over windward and mauka areas. Most showers should be brief, with isolated daytime totals of about a tenth to a quarter inch in favored spots, according to the National Weather Service Honolulu.
Marine And Surf
Trade winds are expected to strengthen into the breezy category by midweek, and forecasters say a Small Craft Advisory may be needed for windier waters and channels around Maui County and the Big Island from Wednesday through the end of the week. South-facing surf stays elevated through the period, with another bump expected Wednesday night into Thursday, though wave heights are still projected to remain below high-surf advisory levels.

What To Know Before You Head Out
Beachgoers should plan on windier afternoons and brief passing showers through midweek and adjust plans accordingly, while boaters will want to keep an eye out for any marine advisories that may be issued. Check the latest forecasts before heading out, and keep a light rain layer within reach if you’ll be in windward or mauka neighborhoods on Tuesday and Wednesday.
