The Lowdown
Alright, I’ve been digging into the data for Nahant Beach, and I’ll level with you—this is a long, quiet stretch. There’s only one spot with any kind of forecast here, and the story is pretty flat for a long time. This is Rusty.
Right now, through the rest of August and into early September, there’s nothing worth paddling out for. Tiny swell, funky winds, and “poor surf conditions” scribbled all over the board. Water temp is about 68°F, right where you’d expect it this time of year.
The one day that finally wakes up is Sunday, September 6th in the morning. That’s your highlight. The swell is 3ft out of the E, period around 11 seconds, and the combined energy is moderate at 238. What makes it special is the wind—glassy, dead calm. That means clean, smooth faces. The optimum swell direction for Nahant Beach is ENE, so this E swell is a bit oblique, but with those glassy conditions, it’s the best thing we’ve seen in two weeks. Beginners should be fine with 3ft, but it’s not a total learner wave. Expect the place to be crowded, so get there early.
Everything else in the forecast is forgettable. There’s a little bump around September 4th and 5th with waves around 2ft to 3ft and moderate energy, but the wind is blowing 15 to 22 mph from the north, making it choppy or cross-chop. Not worth it. After that Sunday morning the 6th, the swell fades straight back into tiny junk.
So if you want clean waves, your only real shot is that Sunday, September 6th morning session. Everything else is best left for another day.
Rusty.

Information about the Nahant Beach Surf forecast
The above surf forecast table for Nahant Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nahant Beach can be found by selecting the local surf guide option on the grey menu. Our Nahant Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Nahant Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
