Numerous showers, locally heavy at times, are expected to continue for Kauai County, forecasters said, along with isolated showers due to a low-pressure system to the northwest.
The National Weather Service says some of the showers may make it to Oahu, but the system is expected to drift away to the north from Friday onward, and easterly trades are expected to return for the weekend.
Today’s forecast ranges from partly cloudy on Oahu to partly sunny for Maui, with highs from 84 to 92 degrees Fahrenheit and lows from 69 to 76. Southeast winds range from 15 to 20 mph.
Surf remains below advisory levels for all shores, although forecasters say a series of northwest to north swells are expected to boost surf along north and west facing shores through Friday.
Surf at 9 to 12 on north shores today, however, is expected to lower to 7 to 10 Friday, while surf of 6 to 8 feet on west shores today is expected to lower to 4 to 6 feet on Friday.
Breezy trades are expected to boost surf along east shores, from 1 to 3 feet today to 2 to 4 feet on Friday.
Surf on south shores are experiencing a bump at 5 to 7 feet today but will lower to 4 to 6 feet on Friday.
A small craft advisory has been issued for Maui County windward waters, Pailolo Channel, Alenuihaha Channel, and the windward, leeward and southeast waters of Hawaii island, due to east winds of 15 to 25 knots, effective through 6 a.m. Friday.
An easterly trade wind pattern is expected to return to the island chain on Friday, easing the humidity and cooling air temperatures.
Two record highs, meanwhile, were set for Hilo and Kahului on Wednesday. A record high of 88 degrees was set in Hilo on Wednesday, breaking the previous record of 87 set for that day in 2019. A record high of 95 degrees in Kahului surpassed the previous record of 92 set for that day in 1995.
