The Lowdown
Alright folks, Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty quiet for Nahant Beach. There’s a bit of a wait for anything decent, but let’s walk through it.
The first real chance to get wet comes up on Sunday, September 6th. Through the morning, it’s a write-off – cross-onshore winds and choppy, bumpy conditions with a 5ft swell from the ENE. But hold on, because Sunday afternoon suddenly flips. The wind drops to glassy, and that same ENE swell is still pushing in at 5ft. The combined energy is solid, hitting 422 (moderate to strong), and the period is a short 7 seconds, so it’ll be a bit crumbly, but glassy conditions at a beach break like this are a treat. It’s the best on offer across the whole outlook.
Monday the 7th offers a glimpse of hope with a tiny 2ft, 10-second period swell from the E and glassy conditions in the afternoon, but it’s really just a knee-high cruiser. The combined energy is only 86 (weak), so it’s more of a longboarder’s or beginner’s session.
After that, the surf all but disappears. There are endless days of tiny, weak waves and onshore or cross-off winds. From the 8th right through to the 18th of September, the wave heights barely hit 2ft, with combined energy often dropping below 30 (weak). It’s a long, flat stretch, and the only thing breaking is the wind. A few mornings show clean offshore winds, like on the 10th with 19 mph offshore winds, but with only 1ft of swell, it’s not worth paddling out for.
The only other flicker of life is Saturday, September 19th morning. A 2ft, 6-second period ESE swell rolls in, with a moderate 12 mph offshore wind from the WNW. It’s clean, but tiny. Combined energy is just 57 (weak). For a dedicated soul on a longboard, it might be a fun session, but nothing to get excited about.
So, the standout is undoubtedly Sunday afternoon, September 6th. The glassy conditions and that 5ft of swell make it the only window worth planning around. Everything else is a flat spell crowd-check.
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.
