Swell Summary
North shore surf will remain very small through the weekend until about the middle of next week when a 3 to 5 foot medium to long- period northwest swell could arrive. East shore surf will hold near seasonal levels today then slowly lower through early next week. A mix of southeast, south and southwest swells will keep small surf rolling into south facing shores through Monday. A slight bump in south shore surf is possible Monday night through mid week as a slightly larger long- period southwest swell moves through.
