Swell Summary
A pair of north-northwest swells are due this week. The first swell will be peaking today near seasonal average, then slowly lower Friday and Saturday. The next, slightly larger, swell will arrive Saturday, and north shore surf may approach the advisory level during its peak Sunday. This swell will gradually decline Monday and fade by Tuesday.
South shore surf will remain near to below seasonal average during the next couple of days. Forerunners of a south-southwest swell will arrive Saturday. The swell will likely peak above seasonal average Sunday and decrease Monday and Tuesday.
The steady trade winds discussed above will generate rough trade wind swell and keep east shore surf near seasonal average.
