A weakening cold front will approach from the northwest today, then slowly dissipate as it moves through the island chain tonight through Tuesday night.

Winds will become breezy and out of the southwest at 15-20 mph by afternoon. Some showers, particularly over leeward neighborhoods are expected with the front. Then weak high pressure will build over or just north of the state Wednesday through Thursday night, bringing another land breeze and sea breeze weather pattern to the islands.

A stronger area of high pressure will build well north of the state Friday and over the upcoming weekend, allowing trade wind weather to finally return to the island chain.

The current small northwest swell will linger into today. A broad surface low with a captured fetch of storm force winds aimed at the main Hawaiian islands is sending a large northwest swell toward the state.

The latest guidance from the Wave Watch III model continues to indicate this swell will build during the day on Tuesday, then peak late Tuesday night and early Wednesday, before gradually lowering through the rest of the week. Surf produced by this swell will likely reach high surf warning criteria along most north and west facing shores of the smaller Hawaiian islands starting Tuesday afternoon or evening.
