The Lowdown
Alright, grab your board and let's talk about what's ahead here at Nahant Beach. We've got a bit of a flat spell on our hands, to be honest. The whole 16-day window is looking pretty quiet, with only a couple of tiny windows where it’s even worth paddling out. This stretch is going to feel like a bit of a pause button.
The first bit of hope comes on the afternoon of Sunday, September 6th. It’s not going to be epic, but we’ll see a small pulse of swell around 3 ft out of the ENE. The trick here is the wind goes glassy. That’s a real treat, because it means the surface will be clean and smooth, perfect for a beginner session. The wave energy is weak, at (111), so it’s a mellow, friendly setup for learning. The crowds here are described as "often", so don't be surprised if there are a few other folks out enjoying that rare glass.
After that, the swell just completely tanks. We get a little bump on Monday the 7th with a 1 ft to 2 ft ENE swell and clean cross-offshore winds, but the energy is barely there at (56). The water temperature is about average for this time of year, so a wetsuit is still your friend.
Then we hit a massive dry spell. From Tuesday the 8th all the way through to the end of the window on September 20th, the waves are barely a ripple. We get some clean days with offshore winds, like Thursday the 10th with a solid offshore breeze up to 19 mph, but the swell is a pathetic 0.7 ft to 1.0 ft. It’s just not surfable. The combined wave energy drops into single digits or low teens, with a couple of brief blips in the 30s and 50s. For a spot that is usually "consistent," this is an unusually flat and blank run.
The only real standout, if you can call it that, is that Sunday afternoon glass-off. It’s the best on offer, but it’s for the absolute beginners only. For anyone else, it’s going to be a frustrating two weeks. The long-range look on September 18th shows some clean, moderate offshore wind and a very long period (12 seconds) groundswell, but it’s only 0.7 ft. That’s a tease, not a ride.
So, keep an eye on the charts, because forecasts can always change, but for now, this stretch is looking more like a good week to wax the stringers and tune up the truck.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Nahant Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
