weekend.
South shore surf will be near April average through tomorrow,
followed by a larger south-southwest swell on Tuesday. Surf along
south facing shores is expected to peak above summer average heights
Tuesday and Wednesday, then decline Thursday and Friday.
Small surf along east facing shores will be near current heights
through Monday, then drop on Tuesday as southerly winds develop.
