Surf rising, vog lingers

Volcanic haze over Oahu and other western islands will continue with varying degrees of haziness as surf rises to giant levels Monday night.

The National Weather Service expects to issue a high surf warning Monday night as two new swells bring extra-large surf to north and west shores of most islands. The surf should remain at warning levels Tuesday and a new swell should keep huge surf coming in through Wednesday.

The current swell remains at advisory levels through 6 a.m. Monday for north and west shores of Kauai County and north shores of Oahu, Molokai and Maui.

Forecasters are expecting a series of weak fronts to pass over or near the islands over the next week, creating variable winds and periods of vog.

The fronts could bring a few more showers to the islands, but is not expected to bring heavy rain.

The forecast for Honolulu and south shores of Oahu calls for cool nights, light winds and hazy conditions.

Monday should be sunny in the morning and partly sunny in the afternoon as clouds form over leeward areas from daytime heating. Highs will be between 75 and 80 degrees. Winds will turn easterly and remain light at 10 mph.

Monday night should be hazy and cool with low temperatures between 58 and 66 degrees, with winds turning westerly at 10 to 15 mph after midnight.
