The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for Nantasket Beach over the next couple of weeks.
Straight up, I gotta be honest with you – this is a tough stretch. The 16-day outlook is looking pretty bleak for any decent surf. We’ve got a long, dry spell of flat, weak, or messy conditions starting now. The first few days, from Saturday the 29th through to Tuesday the 1st, are just plain poor. Tiny swell at 0.2ft to 2ft, mostly cross-onshore or light winds, and the combined energy is barely a whisper at 53 (Saturday morning) or even lower. You’re better off finding something else to do.
We’ll head into a bit of a gap here with no real recommendations. The swell picks up slightly on Thursday the 3rd, with a 4ft swell from the SE, but it’s a short-period 5-second windswell, and the energy is only moderate (107). The wind is offshore though, which is a major positive – clean conditions. But the waves themselves are just poor quality. Friday the 4th and Saturday the 5th offer similar stories: knee-to-waist high, clean, but still poor surf. The energy stays moderate (around 106 to 108), but the period is still short, so it’s just not shaping up.
Finally, on Sunday the 6th of September, we get a glimpse of something. It’s still not great, but the morning shows 3ft from the ENE with a bit more period at 9 seconds, and the wind is clean cross-off from the NNW. The energy is a weak 87, and the surf comment says "surfable waves but very ordinary conditions." That’s as good as it gets. It’s the only surfable session in the whole 16 days, but it’s a far cry from a standout.
The rest of the run is a mess. Monday the 7th has a 5ft swell from the E, but it’s a 6-second windswell with cross-on winds, so it’s just a bumpy, close-out mess. Even the bigger swells are short-period and poorly directed. The water temp is about average for the time of year, nothing unusual.
So, the honest truth? This is a blank run. There’s really nothing to get excited about. If you’re desperate, Sunday the 6th morning is your best shot, but keep your expectations low. In this area, it can be like this at times, and forecasts can change. But for now, I’d be looking at the lake or the river for a paddle.
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.
