The Lowdown
Alright, it’s Rusty here. Let’s not beat around the bush; this is a tough stretch for surf at Nahant Beach. We’re looking at a long, empty run with nothing in the 16-day window that’s worth paddling out for. The pickings are about as slim as they get.
The overall pattern is a lot of small, weak, and short-period energy, mostly from the SSE or ESE, which doesn't line up with the break’s preferred ENE direction. The winds are often cross or onshore, making things messy. If your heart is set on it, there is a tiny window that stands out above the rest, but it’s still just barely "surfable."
The only moment that gets close to a wave is on Wednesday, 22nd July, in the afternoon. The water temp is running normal for the time of year, so no surprises there. The swell picks up a little to 4ft from the SE, but it's not the right direction for this spot. The real positive is that wind swings offshore from the W at 15 km/h, cleaning things up. The combined swell energy reaches 192 (moderate), and it’s the only time the report calls it "surfable waves." But let’s be honest – 4ft of short-period SE swell on a beach that’s exposed to the ENE is not going to be your day to remember. The sets will be fat and weak, and you'll be scratching for anything with a face.
The Wednesday morning before that had 5ft swell, but that was crossed-off with a 20 km/h WSW wind and the period was only 6 seconds, so too messy to be any good.
After that, we’re back to the doldrums. Thursday the 23rd sees a bit more energy (111) but it's straight onshore from the ESE at 15 km/h, so forget it. The rest of the weeks are a graveyard of small, weak, and choppy conditions. There’s a glassy morning on Monday, 27th July, but with only 3ft of short-period NE windswell and no energy, it’s just flat and smooth.
This is a classic case of a long stretch with no real surf. For a break that can be consistent, this blank run is unusual. Still, forecasts can change, but right now, don't waste the gas.
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.
