Alright, Rusty here. Let’s talk about what’s shaping up.
Truth be told, the next week and a half is pretty flat and forgettable for Nahant Beach. We’re looking at a long stretch of tiny, weak waves – mostly under 2 feet – with a lot of cross-onshore breeze. That combo means small, choppy, messy conditions that just aren't worth paddling out for. The wind does turn offshore and cross-offshore from the 13th to the 17th, cleaning things up, but there’s simply no swell to work with. You’ll be bobbing around on ankle-biters. This gap in quality surf runs from now all the way through to the end of next week.
Now, here’s where it gets interesting. Hold on for Monday, the 20th of July. That’s our one true standout in the whole 16-day window. Monday morning looks set to deliver. We’ve got a clean 7-foot swell rolling in from the ENE, with a short period of 7 seconds. The energy is solid, with a combined swell energy reading of (375), which is moderate to strong – you’ll feel that push. What really makes this session special is the wind: it’s going glassy. Dead calm. That’s a rare treat at a beach break like this. You’ll get smooth, clean faces with that much swell. Because the swell height is over 5 feet, it’s getting a bit too big for beginners, and with that short period, it'll be a bit dumpy and quick. For the experienced crew, it’s game on. The water temp is sitting at 68°F, which is about average for this time of year, so nothing out of the ordinary. Just keep in mind that afternoon brings rain showers and a cross-onshore wind, ruining the fun, so make the most of that morning window.
The rest of that week into the weekend sees the swell drop back down to waist-high or smaller, and the onshore wind returns, so that Monday morning is your only real shot.
As for crowds, Nahant Beach is consistent enough and that Monday morning glassy session with a decent size swell will likely draw a crowd. Expect it to be busy, especially with it being so clean.
So there you have it. A whole lot of waiting for one solid morning. That’s the deal.
Rusty.

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.
