The High Surf Advisory has been extended for the east facing shores of the Big Island until 6 p.m. Monday. Surf along east facing shores could reach heights of 5 to 8 feet.

Tonight

Mostly cloudy skies are expected in windward and mauka areas tonight with likely showers in the forecast. Leeward areas should be mostly cloudy becoming mostly clear as the land breeze kicks in and pushes our clouds out to sea. Winds are out of the northeast from 5 to 20 mph. Low temperatures are expected in the range of 66° to 73° with a low of about 49° at 5000 feet.

Moonrise: 3:03 p.m.

Moonset: 4:00 a.m.

Next Full Moon: Dec. 6 at 2:27 a.m.

Next New Moon: Dec. 21 at 3:36 p.m.

 

Looking Ahead 

High pressure is expected to weaken over the next couple of days. Showers will mainly favor windward and mauka areas with some passing leeward from time to time on our breezy winds. An increase in high clouds is expected starting the middle of this week particularly for leeward areas. Rainfall could also increase for the second half of the work week, will keep an eye on it.
