Sumner Avenue in Strathmere is a designated surfing beach that offers a relaxed vibe, making it a good spot for surfers of all levels. As the first break south of Corson Inlet, it benefits from the changing coastline and picks up more of the south swell compared to other areas in Sea Isle. While it can get a bit crowded, especially with beginners, it's generally a friendly spot for those looking to catch some waves.

The surf here works on all tides, but it’s best during mid to high tide since low tide can leave you with a weak break out in the water. You’ll find that Sumner Avenue handles swell sizes from around 2 ft (0.6 m) and is best when the swell direction comes from the Northeast or South. Waves can break both left and right, offering variations for surfers to enjoy. When the wind is coming from the west, the conditions tend to improve, making for a more enjoyable session.

While Sumner Avenue is suitable for beginners, it’s also a spot where more experienced surfers can catch some fun waves, especially on a longboard. Be mindful of the crowds, as you might run into some laid-back locals and other beachgoers enjoying the scene. Overall, it’s a nice place to hang out, surf, and soak up the beach atmosphere.
