Father’s Day Weekend Weather Forecast
A High Surf Advisory is posted for south-facing shores. A slow-moving storm near New Zealand generated a south-southwest swell that will continue to build across Hawaiian waters today. Advisory level surf is expected through 6:00 p.m. Sunday. Waves of 6-8 feet are expected with bigger sets at the best breaks exposed to the swell. The swell is expected to continue to build today and peak overnight.
A Small Craft Advisory is posted for the ʻAlenuihāhā channel and waters to the southeast and lee side of the Big Island through 6:00 a.m. Sunday. Northeast winds from 15 to 25 knots are expected with rough seas up to 11 feet.

Tonight & Sunday night
Partly to mostly cloudy skies are expected tonight with showers likely for windward areas. Leeward areas have a slight chance of a few evening showers, then clearing is expected through the night as the land breeze takes hold. Trade winds are forecasted from 10 to 20 mph. Low temperatures from 71° to 76° are expected.
Breezy trade winds are expected to continue through much of the weekend, followed by a gradual decrease in wind speeds early next week. Clouds and brief showers will favor windward and mountain areas, mainly at night and in the morning hours. An increase in showers is possible for the northern end of the state late Sunday and into early next week.
