Nantasket Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming up for Nantasket Beach. I gotta be straight with you – the next 16 days look pretty flat and quiet. There’s a big gap of nothing worthwhile at the start, so don’t rush to grab your board just yet.

We’re looking at a long stretch of very small, weak swell. The first few days are a write-off, with tiny waves barely breaking and messy onshore winds making a mess of things. The water temperature is sitting at 69°, which is a touch warmer than normal for this time of year – nice for a paddle, but not for a surf.

The first real chance of anything surfable comes around Thursday the 3rd of September. We’ve got a tiny 2ft swell from the ESE with a shockingly short 5-second period – that’s pure windswell, no energy behind it. The combined energy is only 30 to 35 (weak). But the winds are light and cross-offshore, so the surface will be clean. It’s not going to be a session you’ll remember, but it’s the only time in the first week that looks even remotely rideable.

Then it’s back to the doldrums until Sunday the 6th of September. On Sunday morning, the swell bumps up to 5ft from the NE with a 7-second period, and the combined energy jumps to 373 (moderate). That’s the biggest pulse in the whole forecast. But here’s the catch – the wind is howling onshore from the NNE at 16 mph, making it choppy and lumpy. The setup is a beach, so this big, short-period swell with nasty wind is going to be a mess. Honestly, this looks more interesting for kite surfing than paddle surfing. The swell is over 5ft, so it’s not for beginners, but the quality is just poor.

After that, we slide back into tiny, weak surf for the rest of the second week. There’s a brief moment on Tuesday the 8th of September where the morning is glassy with a 2ft, 9-second swell from the E, and the combined energy is 64 (weak). The conditions are clean, but it’s still very small. The rest of the week is a mix of onshore winds and flat spells.

The long-range stuff around the 15th of September shows a pulse of 3ft swell from the NNE, but it’s accompanied by a fresh cross-onshore wind, so don’t get your hopes up.

Overall, there’s no standout day here. The best on offer is probably the Thursday the 3rd of September morning for the clean conditions, or the Tuesday the 8th of September morning for the glassy surface. Neither is going to get your heart racing, but sometimes you take what you can get. The long run of poor surf is a bit normal for this area when the stars don’t align, but forecasts can change.

Stay tuned, and keep your eye on the horizon.

Rusty.
