The Lowdown
Alright folks, Rusty here. Let's be straight with you – this outlook is a tough one for Nahant Beach. We're looking at a 16-day window that's pretty much a write-off for any serious surfing. The pattern is flat and stays flat, so don't be holding your breath for a sneaky swell.
We kick off on Monday morning, July 20th, with almost nothing. A tiny 0.3ft swell from the SE, with a period of 9 seconds, and combined wave energy sitting at a weak 7. The water temp is 66°, which is about 2° cooler than average for this time of year – nothing to write home about. The morning is clean with a light offshore wind, but there's just no power behind it. The rest of the day and the following days are plagued by onshore and cross-shore winds, mostly from the SE, and the swell barely ticks up. By Wednesday afternoon, July 22nd, we get a bit of a pulse with 4ft from the SSE and a period of 5 seconds, but the combined energy is only 70. The wind is light cross-offshore, making it clean, but the wave quality is described as "ordinary." It's surfable, but only just, and certainly not a standout.
The rest of the week stumbles along with tiny, weak swell and poor conditions. A glassy morning on Friday, July 24th, with 2ft from the ESE is nice to look at, but there's no energy (37 combined energy). The pattern continues into the second week – we're talking about prolonged flatness. The combined energy values drop into the single digits by the start of August, with 0.3ft swell and 5 or 6 on the energy scale. There's a clean window on Tuesday afternoon, August 4th, with a strong cross-offshore wind from the SSW, but the swell is still a pathetic 0.3ft. It's a classic case of a blank run being pretty normal for this area when the swell just doesn't show up.
There is simply no standout session here. The best you could hope for is a very small, clean wave on the 22nd, but it's not worth the paddle. For a beach break setup like this, with minimal swell and poor quality, it's honestly more of a kite-surfing window if the wind picks up, but for paddle surfing, it's a solid no-go.
Rusty, signing off.

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.
