The Lowdown
Alright, Rusty here, and I’ve got the goods on Nahant Beach for the next couple of weeks. Let’s be straight with each other: if you’re looking for a proper session, you’re going to be waiting a while. The first real chance of anything rideable doesn’t pop up until Friday, 4th of September, and even that is a bit of a stretch.
For the bulk of the next two weeks, we’re looking at a whole lot of nothing. From now right through to Thursday, the 3rd of September, the swell is tiny, the periods are short, and the energy is weak. We’re talking knee-high slop at best, with combined swell energy mostly below 100, often as low as 24 or 29. The wind is all over the place, too – cross-on, onshore, and generally messy. It’s a pretty grim run of flat, choppy, or just un-surfable conditions. Honestly, it’s the kind of stretch where you don’t even bother checking the cams.
The first sign of life shows up on Friday morning, 4th of September. Nahant Beach will see some chest-high swell push in, around 5ft from the ESE with a short period of 7 seconds. The combined swell energy jumps up to a moderate 345, which tells you there’s some juice in the water, but the light cross-onshore wind (SSE at 3 mph) will keep it a bit bumpy. It’s listed as marginal, so it’s a spot for the keen and the desperate. The following Saturday morning, 5th of September, might actually be your best bet. The swell drops a touch to 5ft from the E, still short-period at 7 seconds, but the wind goes glassy – light SSW at 3 mph. That means the surface will be clean, which is a major positive for this exposed beach break. The energy is still moderate at 184. It’s not going to be a world-beater, but if you’ve been starved for waves, it’ll feel like a gift. For beginners, that 5ft is right on the edge; it’s not huge, but it might feel a bit punchy. Water temps are sitting around 69°F, which is about average for this time of year, so no surprises there.
After that Saturday morning window, the swell fades away again into tiny dribble for the rest of the run. Sunday the 6th and beyond is back to weak, small stuff with energy dropping back below 100. The wind turns cross-offshore for a bit, keeping things clean, but there’s just no power in the water.
So, the bottom line: the only two windows that are even worth a look are Saturday morning, 5th of September, for the clean, glassy conditions on that 5ft E swell, and possibly Friday morning, 4th of September, if you’re willing to deal with a little bump for 5ft. Neither is a standout classic, but it’s all we’ve got.
Stay patient, check the forecast again closer to the day, and hope that glassy window holds.
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.
