Overview
Longnook to Ballston Beach is a sand-bottomed beach break on the outer arm of Cape Cod, offering both lefts and rights along its sandbars. The curve of the Cape shapes what reaches this stretch, and the currents grow stronger the closer you get to the northern tip, so keep an eye on the water once you paddle out.
When It Works
The bank draws swell from north through east-northeast to southeast (N-ENE-SE), with northeast the direction that lines it up best. It works from 0.6 m / 2 ft to 3.7 m / 12 ft. The curve of Cape Cod blocks any decent southeast swell from getting in here, so don't count on those pulses to deliver. Weaker, lumpy northeast wind swells can still groom rideable conditions on the less battered sandbars, and the beach turns smaller and more manageable when big southeast swells are running elsewhere.
Wind and Tide
Look for a southwest offshore wind, which also tends to bring the better sessions. Strong, regular northwest winds batter this stretch, so those days are usually a write-off. The bank favors lower water, working on low and mid tide, with a rising tide generally the better call.
Local Tips
Expect an uncrowded lineup, and the water is usually clean.
Access
There's a car park with paid parking, along with restrooms, showers, and a lifeguard on hand. In summer, arrive early to snag a pay-to-park spot.
