Big waves are the big weather story this weekend.
A new northwest swell will begin rolling in late tonight and peak on Saturday with waves approaching 50 feet.
The National Weather Service has posted a High Surf Warning in anticipation of those waves.
North shores are forecast to be 35-45 feet. West shores could be 23-32 feet. Water run-up along the coastlines will be greatest at high tide.
Waimea Bay will see a high tide of +1.65 feet at 2:27 a.m. on Saturday. It will be +1.72 feet at 2:59 a.m. on Sunday.
Officials are warning those who live or work along north and west shores to prepare now for the weekend waves.
Today, we are between swells and the surf will be 14-18 north, 8-12 feet west, 2-4 feet east, 1-3 feet south.
Weather will be very pleasant through the weekend. Winds will be light and variable.
Convective heating will create sea breezes in the afternoons and there could be isolated showers over interior sections. Trade winds will begin their return late Sunday and build to windy by Wednesday.
High today in Honolulu will be 82 degrees.
