The Lowdown
Alright folks, Rusty here. Let’s get into it for Nahant Beach. I’ve got to be straight with you – the next 16 days look pretty grim. We’re looking at a long stretch of small, weak, and messy conditions, with a few fleeting moments that might be worth a paddle if you’re desperate.
The Big Picture: A Long, Flat Spell
The truth is, for the first week, from July 23rd right through the end of the month, it’s a write-off. The combined energy of all swells directed here is in the low double digits (42) and often dropping into the teens (18, 20). That’s weak, anemic energy. Swell heights are tiny, between 0.7 ft and 2 ft, with short, weak periods around 7-8 seconds – that’s just windslop. The wind is mostly cross-on or onshore, so the surface is choppy and messy. There’s just nothing to work with.
The Only Glimmer of Hope (Late July)
Now, there is one day that stands out, but it’s not for the faint of heart. On the morning of Wednesday, July 29th, we see a bump in the swell. The forecast shows east energy at 7 ft, with a period of 8 seconds, and the combined energy jumps to 817. That’s a legitimate amount of power for this spot. The wind is a light, cross-shore breeze from the north-northeast at 6 mph, which will keep it relatively clean. But here’s the catch: that 7 ft swell is big. For a beginner spot like Nahant Beach, this is expert territory. It’s going to be a powerful, chunky wave, and the short period (8 seconds) means it’ll be a bit dumpy. This is a true stand-out for the crowd that can handle heavy, close-out shorebreak, but it’s not a day for the average surfer.
The Second Week: Back to the Desert
After that brief pulse, we slide right back into a drought. From July 30th all the way through to August 7th, the conditions are depressing. The combined energy drops back to the 20-40 range, and swell heights are consistently under 3 ft. The wind is all over the place, but rarely favorable. We get a few moments of glassy conditions on the morning of July 30th and again on August 4th, but with only 3 ft and 0.7 ft of swell respectively, there’s just no wave to ride. It’s flat, and it’s going to stay flat.
The Crowd Factor
When the surf is this poor, crowds aren’t really a concern at Nahant Beach. It’s a consistent spot, but when the waves are this small, most people will stay home. The only time it might get busy is that Wednesday morning, July 29th, if the swell actually shows up, but given the conditions, it’s a risk.
The Verdict
Honestly, this is a tough run. The standout is that Wednesday, July 29th morning, but only for the experienced. For everyone else, the forecast is a blank. It’s the kind of dry spell where you might want to check the tide charts for a longboard and a tiny, clean day, or just count on the forecasts changing. It doesn’t usually stay this poor for this long.

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.
