The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this Nahant Beach outlook is a tough one. The whole 16-day window is a real struggle. We’ve got a long stretch of nothing worthwhile on the cards, so don't be holding your breath for a proper session.
Looking at the entire run, there’s a big gap right from the start. The first few days are basically a write-off. The swell is tiny, mostly under 1 foot, and the wind is all over the shop. You’ll see some offshore or glassy conditions, but with flat waves, it doesn't mean a thing. The combined energy is in the weak basement, often below 20 (16-20). It’s just not doing anything.
The first real pulse of energy shows up around Tuesday, September 15th. The swell jumps to 5.6 feet from the ENE, with the combined energy climbing to 211 (moderate wave energy). That’s the biggest we’ll see. But here’s the letdown: the wind is onshore from the ESE, and the period is a short, weak 6 seconds. That’s a recipe for sloppy, jumbled-up surf. It's likely too big for beginners at 5.6 feet and the quality is just poor. The following day, Wednesday the 16th, drops to 3 feet from the ENE, with a cleaner cross-off wind from the WNW, but the energy is back down to 79 (weak). Still not worth a paddle.
The water temp is about average for this time of year, so no shock there. Nahant Beach is a consistent spot, but this run is a classic example of a dead spell. The setup might look more interesting for kite surfing on those bigger, windier days than for paddle surfing.
For the rest of the period, it’s back to the same story: tiny waves, weak energy, and nothing to get excited about. The forecast can change, but right now, save your energy.

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.
