The Lowdown
Right on, let’s have a look at what’s in store for Nahant Beach over the next couple of weeks.
Honestly, the outlook is a bit of a flat spell for the most part. We’ve got a long stretch of tiny, weak waves and mostly poor conditions, so you’re not missing much if you leave the boards at home for a while.
The first real chance of anything rideable comes on Saturday the 19th. It’s not a classic, but at least there’s a pulse. The morning of the 19th, the swell bumps up to about 4 ft out of the NE, with a combined energy of 112 (moderate), but the period is a short 6 seconds, so it’s going to be a bit jumbled and fat. The wind goes glassy in the morning, which is a major positive – it’ll be clean and smooth on the surface. The water temp is about average for the time of year at 66°F. This is a beginner-friendly spot, and with the swell under 5 ft, it’s fine for learners. The afternoon gets messy as the wind swings cross-onshore at 12 mph, so the morning window is the clear pick. Crowds are a possibility here, as it can get busy.
Before that, there’s a very small bump on the afternoon of Tuesday the 15th, with 3 ft swell from the SSE and a combined energy of 41 (weak), but the period is a short 4 seconds, so it’ll be weak and choppy. Not really worth paddling out for.
Then on Thursday the 17th, we see a bit more size, with 3 ft to 4 ft from the ENE, but the wind is cross-onshore and choppy both morning and afternoon. The combined energy sits around 80 to 85 (weak), and the period is still short at 5-6 seconds. It’s going to be a messy, bumpy ride.
After the 19th, it dries right back up. From the 20th through the 24th, we’re back to tiny 0.7 ft to 1 ft swells, with negligible energy, and mostly onshore or cross-shore winds. It’s a complete non-event for the rest of the outlook.
So, if you’re looking for the best of a very quiet bunch, your window is the morning of Saturday the 19th of September. It’s the only day with a bit of size, glassy conditions, and the potential for a few fun ones on a longboard. Otherwise, it’s a blank stretch until then, and after that it’s flat again.

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.
