The Lowdown
Alright folks, Rusty here, and we’re taking a long, hard look at Nantasket Beach for the next couple of weeks. Gotta be straight with you, it’s a grim picture for the most part.
The whole 16-day window kicks off with a dud. We don’t see any decent surf until Sunday afternoon, September 6th. From then on, it’s a whole lot of waiting for scraps.
Our only real chance to get wet comes on Sunday afternoon, September 6th. Nantasket Beach picks up a small ENE swell, around 5ft, which is manageable but might be a bit punchy for beginners. The combined wave energy here is moderate (439), and the wind goes glassy with just a slight air. That’s the golden ticket – glassy conditions make even small waves fun. The direction is a touch east of the optimum, but when it’s that clean, I ain't complaining.
Monday morning, September 7th, drops back to 3ft with a moderate energy (194) but a cross-shore wind messes it up. By the afternoon, the swell gets tiny at 2ft and the energy is back down to weak (94), though the wind is glassy again. It’s rideable, but ordinary.
After that, it’s a long, slow death. The rest of the first week and all of the second week are filled with tiny, weak swells and poor surf conditions. You’ll see a spike on Saturday, September 12th, with 6ft from the ENE and moderate energy (347), but that onshore and cross-onshore wind kills it completely. That setup and exposed beach is probably more interesting for the kite surfers than for us paddle guys.
There’s a flicker of life way out on Saturday, September 19th, with a 3ft swell from the ESE and moderate offshore wind, but the energy is weak (68), and that’s two weeks out, so keep your expectations very low on that one.
The water temp is about average for this time of year, so no surprises there.
So, to sum it up: the only true standout is that glassy window on Sunday afternoon, September 6th. After that, you’re mostly watching the tide come in and go out. It’s gonna be a quiet one.
Rusty.

Information about the Nantasket Beach Surf forecast
The above surf forecast table for Nantasket Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nantasket Beach can be found by selecting the local surf guide option on the grey menu. Our Nantasket 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 (Nantasket 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 Nantasket 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.
