Honolulu's Sunday forecast calls for mostly sunny skies and a high near 82 degrees. Returning northeast trade winds, with gusts up to 29 mph, will make exposed beaches, roads and outdoor plans feel noticeably breezier.
Showers Ease As Trade Winds Return
Scattered showers are expected through Sunday, with the best odds in windward and mauka areas and a 50% chance of rain overall. Most new rainfall should stay below a tenth of an inch, while the latest National Weather Service Honolulu forecast discussion says drier air will spread across the islands as the day progresses.
Sunday night should turn partly cloudy with isolated showers and a low near 76 degrees. Visibility could briefly drop in passing showers, so hikers and drivers heading toward higher elevations should be ready for quick changes in conditions.
High Surf And Small Craft Advisories
The latest forecast includes a High Surf Advisory through 6 p.m. Monday for north- and west-facing shores of Oahu, including the North Shore and Waianae Coast. A Small Craft Advisory is also posted for all coastal waters, with exposed waters expected to see waves above 10 feet and stronger northeast winds spreading across the island chain.
East-facing beaches should become increasingly choppy as the trade winds build, while north and west shores remain the bigger concern for elevated surf. The update is a significant shift from Hoodline’s earlier Halloween weekend forecast, which did not include the current coastal advisories.
Windy Pattern Holds Through The Week
Monday should be mostly sunny with a high near 84 degrees. Trade winds will stay breezy into Tuesday, when winds are forecast around 23 mph with gusts up to 32 mph.
Light trade showers may continue through the rest of the week as breezy conditions persist.
Forecasters are also watching a possible tropical system southeast of Hawaii later in the week, with a 50% chance of development within seven days. The current outlook says any system that forms is expected to remain south of the islands rather than move toward Hawaii.
