The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Nahant Beach. I gotta be straight with you, this forecast is a tough one to write. We're looking at a long, long stretch of small and messy conditions, so you'll need to be patient.
Forget about any real surf for a while. There’s a big gap of quiet water kicking things off. The first real sniff of a wave isn't until later in the first week, and it’s nothing to get excited about. We’re talking about a sea that’s mostly flat or blown out.
There's a small bump possible on September 3rd, but it's got problems. Swell heights around 4ft from the SE, but the period is a short, weak 6 seconds, and it’s coming with moderate rain and strong cross-shore winds. The combined energy is only moderate at best (75). It’s not a surfing day, more of a messy, choppy one.
We don't get another look until September 10th. Thursday the 10th shows a little pulse of energy. The morning has some swell from the ESE at 1ft with a period of 14 seconds. That long period suggests there's some energy there, even though the height is tiny. Combined energy is still weak (47). The problem is the wind is cross-on from the NE, chopping it up. The afternoon might be slightly better with a 2ft swell from the SE, a period of 12 seconds, and slightly less energy (88). But again, it’s cross-on from the ENE and looks pretty ordinary.
The best of a bad bunch looks like Saturday September 12th. The morning brings a 2ft swell from the ESE with an 11-second period. The combined energy finally gets close to a moderate level (92). It’s still cross-on from the NE, but it's a light breeze, so the chop will be minimal. It’s not a standout by any stretch, but in this forecast, it’s the most promising window for a few small, grovelly waves. The afternoon looks similar but a little bumpier.
The water temp is about 68°F with a normal anomaly of 1°, so it's average for this time of year.
Look, it’s a flat spell for Nahant. Keep your expectations on the floor, and maybe the small windows on the 12th might just give you a fun little session if you’re desperate.
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.
