The current small north-northwest swell will continue to slowly decline tonight, followed by a moderate northwest swell that will build down the island chain Monday. A gale low developing several hundred miles north of the islands on Monday will produce a large, short lived, medium period north-northwest swell that will build across the western end of the island chain Monday night and Tuesday. Surf will likely exceed the high surf advisory level along north facing shores of Kauai, while large surf may impact Oahu. The swell will decline to moderate levels on Wednesday and Thursday. Forecast confidence decreases later in the week due to uncertainty in the location and intensity of another surface low that could develop near Hawaii and produce a large, short to medium period northerly swell.
Moderate east shore surf will decline Monday, and while the source for east swell will fade through the rest of the week, some east shores will experience periods of larger wrapping north swell. Small surf will prevail on south shores this week, though conditions may become rough as southerly winds increase Monday and Tuesday.
