Expect lighter winds and warmer, more humid conditions for the Kamehameha Day holiday and into the weekend.

“Winds will be starting to weaken a little bit (Thursday),” said John Bravender, a meteorologist with the Honolulu office of the National Weather Service. “We’ll still have tradewinds but it will not be quite as strong as today.”

Winds will continue to weaken over the weekend, increasing the chance of sea breezes and afternoon showers over leeward areas as clouds build up over mountain slopes.

“It will probably be more humid over the weekend once the winds die down,” Bravender said.

The weather for Saturday’s Kamehameha Day Parade calls for sunny skies in the morning and partly sunny skies in the afternoon with highs between 80 and 87 degrees and northeast winds of 10 to 15 mph, shifting to the south in the late morning and afternoon.

Similar weather is expected Sunday during the Pan Pacific Parade. There could be some isolated afternoon showers.

There should be some small to moderate surf on all shores through the weekend. A moderate windswell from former Hurricane Blanca could arrive Thursday, bringing 2- to 4-foot waves to east shores through Saturday. North shores will also see a bump to 2 to 4 feet Thursday, but that swell is expected to diminish over the weekend. Other areas can expect 1- to 3-foot surf.

South shores may also see a small bump from a storm near New Zealand on Saturday.
