The Lowdown
Alright folks, Rusty here. Let’s get straight into it for Nahant Beach.
First up, I gotta be real with you – the next week and a half is a tough slog. We’re looking at a long, dry spell with hardly anything worth paddling out for. The water temp is sitting at a pretty mild 66° right now, which is about average for this time of year, not too crazy.
The first real glimmer of hope doesn't show up until Monday the 21st of September. We start seeing some swell push in, but it’s all onshore wind, so it’s messy. By Monday afternoon, the swell is picking up to 7ft from the ENE, with a short period of 6 seconds. That’s a lot of churning water (combined energy of 291), but with the wind howling on it, it’s going to be a washing machine. That’s more of a kite-surfing show than a clean paddle session.
Then things get a bit wild. Tuesday the 22nd of September is the real standout, but it’s for experts only. Overnight, we get a massive pulse of energy. Tuesday morning is showing a 12ft swell from the ENE, with a period of 10 seconds. The combined energy is a huge 3274, which is a serious amount of power. But the wind is howling onshore at 22 mph with heavy rain. This is not a beginner wave; it’s a heavy, dangerous beast. The wind is just too strong to make it clean, so it’s a miss for a good surf.
The end of the week finally starts to turn. On Thursday the 24th of September, we get our best shot. The morning is clean, with a light offshore breeze from the NW. The swell drops to a manageable 3ft from the ESE with a period of 8 seconds. The combined energy is a modest 78, and the wind is light and clean. The conditions are described as "surfable waves but very ordinary," which is a pretty honest call. It’s not going to be epic, but it’s the only window in the whole 16 days where you can get a clean, rideable wave without fighting the wind. That’s your best bet if you’re desperate for a surf.
Other than that, the rest of the period is a bust. The onshore wind and rain just ruin the potential. It’s a long wait, but that’s Nahant for you sometimes.
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.
