Trade wind weather to make a brief return

Gentle to moderate trade winds will return as a cold front dissipates and the an upper level trough that brought heavy rain and thunderstorms to the east end of the state trough moves south of the Big Island. The trades will bring the usual windward and mauka showers through Tuesday, when winds will be disrupted again by another approaching front, which could increase showers midweek. That will be followed by a stronger front that will bring more showers Friday and Saturday.

A new northwest swell will rise into Sunday, with a high surf warning posted for the north and west shores of Niihau, Kauai, Oahu and Molokai and the north shores of Maui and the Big Island. There’s also a high surf advisory up for west shores of the Valley Isle. A larger swell will be possible late Wednesday and could peak Thursday near warning heights. East shores will remain small with the lighter trade winds, while south shores could see a small bump midweek from a south-southwest swell. For mariners, a small craft advisory is up for most coastal waters exposed to the northwest swell.
