Hot, humid weather with little relief from the tradewinds is expected to continue through the weekend.
The National Weather Service says a cold front approaching the islands from the northwest is cutting off the tradewinds.
Cloud build-up from daytime heating could bring some afternoon showers to mauka and interior areas.
High temperatures of 83 to 89 degrees are expected through the weekend and possibly the early part of next week.
Overnight lows will be between 67 and 74 degrees.
“Especially for Oahu today and tomorrow, tradewinds wil be absent,” said Tom Birchard, a meterologist with the Honolulu office of the National Weather Service.
Light tradewinds may start to return on Sunday, with more typical, cooling tradewinds back on Monday.
“It makes it (heat and humidity) feel worse when winds are light like this,” Birchard said.
Surfers may find some relief from the high temperatures with swells on the north, south and east shores.
A south swell is expected to peak Friday and subside gradually through the weekend with 4- to 7-foot wave faces Friday, declning to 3 to 5 feet Saturday. Winds from former Hurricane Andres are bringing 3- to 5-foot surf, rising to 4 to 6 feet Saturday. North shores are also getting a bump from a swell with 2- to 4-foot waves rising to 4- to 6-foot surf Saturday.
