A high-surf advisory for the north- and west-facing shores of isles stretching from Niihau to Molokai, and the north-facing shores of Maui, remains in effect until 6 p.m. today.

The current northwest swell will continue to lower over the next few days, according to the National Weather Service. Surf is expected to reach 10 to 15 feet high along the north- and west-facing shores of Kauai County and the north-facing shores of Oahu, Molokai and Maui.

Surf is expected to reach 8 to 12 feet along the west-facing shores of Oahu and Molokai.

The impacts are moderate, but the public should still expect strong, breaking waves and longshore and rip currents, making swimming difficult and dangerous. Beachgoers, swimmers and surfers should exercise caution and heed all advice given by Ocean Safety officials.

The weather, meanwhile, felt colder than usual Wednesday, and is expected to continue today.

In a tweet today, the NWS announced that all four of its main sites monitoring daily climate date — in Lihue, Honolulu, Kahului and Hilo — failed to reach 80 degrees Fahrenheit Wednesday. The normal high for these stations ranges from 79 to 81 degrees Fahrenheit. When combined with low dew points, “it certainly felt chilly,” the NWS said.

Forecasters said showers are expected to linger over the windward side of Hawaii island today, while drier and cooler air and breezy trades will continue to come from the northeast over the smaller isles through tonight.

The trades shift to a more easterly direction Friday through the weekend, but wetter weather conditions are possible going into Christmas Eve on Monday.
