Trades are expected to continue through this Election Day in Hawaii today, then diminish and veer southeast midweek as a cold front approaches, forecasters said. Showers favoring windward and mauka areas are still expected, but rainfall accumulations should remain light.

The National Weather Service said the front approaching from the northwest will diminish trades once again across the western end of the isles, bringing a period of heavy showers over Kauai and Oahu. A few thunderstorms over Kauai are also possible, forecasters said.

Today’s forecast is partly sunny with scattered afternoon showers, highs from 84 to 89 degrees during the day, and lows from 70 to 75 tonight. East winds remain around 15 mph today and tonight.

Surf on the North Shore ramped up to 10 to 14 feet today, just shy of advisory levels, but will ease to 7 to 10 feet on Wednesday.

Forecasters said a reinforcing swell is forecast to arrive today, and keep surf along the north shores near the early November average and just below the high surf advisory threshold.

Surf on west shores at 6 to 8 feet today lower to 4 to 6 feet on Wednesday. Surf on south shores bump up from 1 to 3 feet to 3 to 5 feet Wednesday, and on east shores from 1 to 3 feet to 2 to 4 feet on Wednesday.

Another moderate, northwest swell is forecast to fill in late Wednesday into Thursday, then gradually decline and shift out of the north Friday through the weekend.
