Swell Summary
Surf along north and west-facing shores will remain very small during the next 7 days. Surf along south-facing shores will hold at background levels through tonight. A series of small south and south-southwest swells will give a small boost to south shore surf over the weekend, with a further boost up to the seasonal average possible during the middle to latter part of next week. Surf along east-facing shores will hold close to seasonal normals during the next 7 days.
