Nantasket Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s going on in the water for the next couple of weeks.

Honestly, it’s a tough stretch. There’s a four-day gap at the start with nothing worth paddling for, so don’t even bother looking at the ocean until Sunday, September 6th.

Sunday, September 6th is the first day we might see something. That early morning swell at Nantasket Beach jumps to 6 ft from the NE, and the combined energy hits 526 – that’s a solid pulse of moderate energy. The wind is cross-shore though, so it’ll be a bit choppy and rough. This is a marginal session, really only for the experienced lot. That 6 ft is getting into the “too big for beginners” territory, and the period is a short 7 seconds, so it’ll be a bit walled up and messy.

Monday, September 7th is the best we’ve got, and I’m not gonna lie, it’s not a standout. The morning brings a cleaner setup with a light NNW cross-offshore breeze at 6 mph. The swell drops to 3 ft from the ENE, with a period of 9 seconds. The combined energy is 138 – moderate but weak. The water temp is about 67°F, which is pretty normal for the time of year. Clean conditions mean you might get a few fun ones, but it’s ordinary. The waves are small and the quality is just “surfable.” The afternoon goes glassy with a WNW breeze at 3 mph, but the swell drops to 2 ft and the energy falls to 55. Clean, but tiny.

After that, it’s a long, depressing slide. From Tuesday, September 8th all the way through to the end of the forecast, the swell never gets above 4 ft, and most days are under 2 ft. The wind is often cross-offshore or offshore, which keeps the surface clean, but there’s just no push. Wednesday, September 9th is glassy but the swell is only 0.7 ft. Thursday, September 10th has a fresh offshore wind at 19 mph, but the swell is 0.3 ft – that’s a flat day, no two ways about it.

You’ll see a couple of days around Friday, September 11th where the swell tries to kick up to 5 ft from the NE, but the period is a short 6 seconds and the wind is strong offshore at 16 mph. That’s a choppy, blown-out mess. The combined energy is 137 – still moderate, but the surf quality is poor.

The long-range stuff, like Saturday, September 19th, shows a 0.7 ft swell from the E with a long period of 12 seconds, but that’s a whisper. Don’t hold your breath.

The bottom line: The only real window is Sunday morning, September 6th, and Monday morning, September 7th, for clean, small waves. The rest of the 16 days is a write-off. Nantasket Beach is a consistent spot, so it won’t stay this flat forever, but this stretch is a dud.
