Nantasket Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. I’ve got the full 16-day look at Nantasket Beach, and I’m not gonna beat around the bush—it’s a tough stretch. We’re looking at a long, dry gap with no real surf to speak of for the first week and a half, so don’t be in a rush to wax up.

The water temp is sitting at about 69°, which is pretty much normal for this time of year, so at least the water’s comfortable.

The first real pulse of energy shows up around Wednesday the 26th, with a bump in swell from the NNE. We’re talking about 4 ft swell on the Wednesday morning, building to 5 ft by the afternoon. The combined energy ramps up to 103, then 153, so it’s moderate energy. The period is a short 6 seconds though, so this is windswell, not the good stuff. Winds are cross-shore, coming from the SSE, so it’s going to be a bit lumpy and choppy. It’s not great, but it’s something.

Then Thursday the 27th morning brings the biggest swell of the window—5 ft from the NE with a 7-second period, and the combined energy hits 393, which is solid moderate energy. The wind is light and cross-onshore from the SE, so it’s not clean, but the size is there. This is getting into the “too big for beginners” range, and with the short period, it’s going to be a bit of a mess. The afternoon drops slightly to 5 ft, still from the NE, but the wind goes onshore from the E, so it’s choppy.

After that, Friday the 28th morning sees a drop to 2 ft from the ENE, but here’s the standout: the wind swings to light offshore from the W. That’s a clean window. The swell is small, only 2 ft with a 6-second period, and combined energy is just 41, so it’s weak. But if you’re desperate for a clean, glassy-ish session with no crowds (it’s Nantasket, so crowds are only sometimes a problem), this is your best bet. The swell direction is ENE, and the optimum is NE, so it’s close enough.

The rest of the 16 days trails off into tiny, weak surf with energy readings in the single digits and teens. Not worth paddling out for.

So, to wrap it up: there’s a real dry spell until the 26th. The best on offer is the Thursday the 27th for size, but it’s messy. My pick for the cleanest ride is the Friday morning the 28th—small, but clean offshores. Don’t expect much else.

Rusty.
