The Lowdown
Alright folks, Rusty here. Let’s get into it for Nantasket Beach. I’ve had a look at the next couple of weeks, and I gotta be straight with you – it’s a tough stretch. We’re looking at a long, dry spell before anything remotely worth paddling out for shows up.
The first real chance to even think about a wave comes on Monday morning, the 7th of September. We’ve got a tiny 2ft NE swell pushing in, but with a short period of just 7 seconds, it’s not gonna have any punch. The good news? The wind is a light cross-offshore from the NNW, keeping the surface clean. Water temp is sitting at 68°F, which is about 1°F warmer than average for this time of year, so nothing wild there. Still, the combined energy is a measly 68 (weak), so it’s really just a knee-high dribble. It’s surfable if you’re desperate, but it’s ordinary.
The rest of the first week and into the second is a total bust. From Tuesday the 8th all the way through to Wednesday the 16th of September, we are looking at a massive gap of over a week with nothing on offer. The swell drops to practically nothing – we’re talking 0.3ft to 0.7ft scraps. Even when the wind goes glassy or offshore, there’s just no ocean energy to work with. The combined energy values are in the single digits or low teens, which is as weak as it gets.
Now, the outlook does start to get a little more interesting towards the end of the run. On Wednesday afternoon, the 16th of September, there’s a pulse of new swell. It’s 5ft from the NE with a period of 6 seconds. The combined energy jumps to 138 (moderate), and the wind is light and cross-off from the SSW, keeping it clean. It’s still a short-period windswell, so it’ll be a bit lumpy and without much push, but it’s the first sign of life.
The real standout, if you’re an experienced surfer, is Thursday the 17th of September. We’ve got a solid 8ft NE swell rolling in. The combined energy is a whopping 788 (strong), so there’s plenty of power. But, and it’s a big but, the wind is onshore from the ENE at 9 mph, and the period is a short 8 seconds. This is going to be a tough, choppy, and messy beast. At this size and with onshore wind, Nantasket Beach is going to be a washing machine. It’s really only for experts who don’t mind a beating, and honestly, the setup looks more interesting for kite surfing than paddle surfing. It’s a marginal call at best.
Friday the 18th of September hangs in there with a 6ft E swell, combined energy at 671 (strong), but again, it’s onshore wind. The weekend after that, the 19th and 20th, sees the swell fade back down to under 3ft with clean winds but very little energy left.
So, bottom line: if you’re looking for a window, the best bet for clean, small waves is Monday morning the 7th. For the big, gnarly stuff, keep an eye on Thursday the 17th, but don’t expect it to be pretty. For the rest of this stretch, save your wax and wait for a better forecast.
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.
