An approaching cold front has shut down the trade winds. Expect light and variable breezes today. Afternoon sea breezes will likely form. Showers will be spotty and could be briefly moderate to heavy at times this afternoon.
High today in Honolulu will be 85 degrees.
The front will reach Kauai early Friday afternoon and cross over Oahu Friday night. It will move over Maui County on Saturday and then stall. Northeasterly winds that will have built in behind the front will push its moisture back onto the islands and could be enhanced by instability aloft. The most intense shower activity may occur late Sunday over the eastern half of the island chain, but all islands are at risk of seeing heavy weather starting on Friday.
Surf is building along south shorelines and could approach advisory levels tomorrow. It takes 8-foot waves to trigger an advisory in town.
Here are today's wave heights: 3-6 feet north, 3-5 feet south, 2-4 feet west, 2-3 feet east. No marine or weather advisories are posted.
