Nantasket Beach Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about Nantasket Beach.

To be straight with you, this forecast is a tough one. We’re looking at a long stretch of days where the waves just aren’t cooperating. The whole 16-day window is a real mixed bag of tiny, weak swell and messy wind, so there are no true standouts.

From now through the first week of September, don’t get your hopes up. The swell is small, mostly under 3 ft, and the period is short on top of that. The wind is often onshore or cross-onshore, making for choppy, poor conditions. There’s one glimmer on Thursday afternoon, September 3rd, when the wind goes offshore from the WSW at 6 mph and we get a clean combo of 3 ft from the ESE at 6 seconds. It’s the only session that’s even surfable, but the energy is weak – just 64 (moderate wave energy) – so it’s really just small, ordinary waves. It’s not a standout, just the best of a bad lot.

We do get a bump around September 6th and 7th, with swell hitting 4 ft to 4 ft from the ENE. The period stretches to 11 seconds on the 7th, which is a proper groundswell. Energy jumps to 168 (strong wave energy) on the Sunday afternoon. But here’s the catch: the wind stays cross-shore or cross-onshore the whole time, and it’s a beach break. At 4 ft with a crosswind, it’s going to be messy and lumpy. Look, for a kite surfer, that setup could be a hoot, but for a paddle surfer it’s more work than it’s worth.

After that, from September 8th onward, it fades right back to tiny anklesnappers with poor wind again. There’s nothing in this window worth planning a session around.

So, what’s the call? If you absolutely need a paddle on Thursday the 3rd, you might get a few clean little runners, but keep the expectations low. Otherwise, this is a classic New England lull. It hurts to say it, but I’d wait for the next system to shake things up. Forecasts change, so don’t write the whole month off yet.

Rusty.
