Trade Wind Weather Today, Hilda Forecast Uncertain
A Small Craft Advisory is posted for the ʻAlenuihāhā channel as well as Big Island south and leeward waters. Winds of 20 to 25 knots out of the northeast are forecasted with rough seas up to 10 feet. This advisory is posted through 6:00 p.m. Monday. Inexperienced mariners should avoid navigating in these conditions.
A High Surf Advisory is posted for the east side as swell generated by hurricane Hilda builds. The advisory is posted through 6:00 a.m. Wednesday. Wave heights of 6 to 10 feet are expected Monday, building to 8 to 12 feet Monday night and Tuesday. Expect strong breaking waves, shore break and strong longshore and rip currents making swimming difficult and dangerous.

We expect high temperatures from 83° to 88°. Northeast winds are expected from 10 – 20 mph. Partly cloudy skies are forecasted with scattered showers in the morning for windward areas. Leeward spots are expected to be sunny to start with building cloud cover and afternoon upslope showers.
UV index at 12 (“extreme” exposure level)
Partly cloudy skies are expected with scattered showers for windward spots. Leeward spots should be partly cloudy with isolated showers. Northeast winds are forecasted from 10 to 20 mph. Low temperatures from 71° to 76° are expected.
Locally breezy trade winds will gradually decrease through Tuesday. For the next few days showers will remain focused along windward slopes. Trade winds will likely hold into Wednesday with a good chance for a gradual increase in shower activity from the east. In addition, a few heavy showers will be possible on Big Island slopes by Wednesday. Heading into the second half of the work week, the local forecast hinges upon the evolution of hurricane Hilda. Forecast uncertainty associated with Hilda remains high. Hilda, or its remnants, will most likely be clearing the state sometime during the weekend.
