The Lowdown
Alright, let’s go over this stretch again, but in feet and miles per hour.
So, looking at the next 16 days for Nahant Beach, the story is mostly the same: a whole lot of flat, mushy nothing, but we do have one short blast of size in the middle.
Right off the bat, from Tuesday, September 1st through Friday the 5th, you’re looking at junk. Swell is tiny, maybe 0.6 ft to 2 ft, and the energy numbers are just pitiful, mostly in the 10 to 50 range. The wind is onshore or cross-onshore, making a mess of what little ripple is out there. Not worth wetting a wetsuit.
Then we get our only shot. On Sunday, September 6th, the swell jumps to about 5 ft from the NE, with a short 7-second period. The combined wave energy gets into the 200s, so there’s some proper push. The problem is the wind is a fresh cross-onshore at 18 mph, so it’s going to be lumpy and choppy. The afternoon holds at 5 ft, but again, it’s onshore. It’s not clean, but it’s the biggest we’ll see all forecast. A messy option for the experienced crew.
Monday the 7th keeps some of that size, about 5 ft, before it fades quickly.
After that, from Tuesday the 8th all the way to the end on Wednesday the 16th, it completely flatlines. Swell drops below 2 ft, the energy vanishes, and while the wind might clean up, you’re going to be scratching for a ride. The water temperature is about average for the time of year.
So the only reason to get out of bed is that Sunday the 6th and Monday the 7th. It’s the only real pulse of swell in the whole 16 days. For beginners, that 5 to 5 ft surf might be more than they bargained for, so maybe sit this one out.
A long, flat spell with one messy, medium-sized window. That’s the rundown.

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.
