The Lowdown
Alright folks, Rusty here. Let’s talk about what’s going on in the water for the next couple of weeks.
Honestly, it’s a tough stretch. There’s a four-day gap at the start with nothing worth paddling for, so don’t even bother looking at the ocean until Sunday, September 6th.
Sunday, September 6th is the first day we might see something. That early morning swell at Nantasket Beach jumps to 6 ft from the NE, and the combined energy hits 526 – that’s a solid pulse of moderate energy. The wind is cross-shore though, so it’ll be a bit choppy and rough. This is a marginal session, really only for the experienced lot. That 6 ft is getting into the “too big for beginners” territory, and the period is a short 7 seconds, so it’ll be a bit walled up and messy.
Monday, September 7th is the best we’ve got, and I’m not gonna lie, it’s not a standout. The morning brings a cleaner setup with a light NNW cross-offshore breeze at 6 mph. The swell drops to 3 ft from the ENE, with a period of 9 seconds. The combined energy is 138 – moderate but weak. The water temp is about 67°F, which is pretty normal for the time of year. Clean conditions mean you might get a few fun ones, but it’s ordinary. The waves are small and the quality is just “surfable.” The afternoon goes glassy with a WNW breeze at 3 mph, but the swell drops to 2 ft and the energy falls to 55. Clean, but tiny.
After that, it’s a long, depressing slide. From Tuesday, September 8th all the way through to the end of the forecast, the swell never gets above 4 ft, and most days are under 2 ft. The wind is often cross-offshore or offshore, which keeps the surface clean, but there’s just no push. Wednesday, September 9th is glassy but the swell is only 0.7 ft. Thursday, September 10th has a fresh offshore wind at 19 mph, but the swell is 0.3 ft – that’s a flat day, no two ways about it.
You’ll see a couple of days around Friday, September 11th where the swell tries to kick up to 5 ft from the NE, but the period is a short 6 seconds and the wind is strong offshore at 16 mph. That’s a choppy, blown-out mess. The combined energy is 137 – still moderate, but the surf quality is poor.
The long-range stuff, like Saturday, September 19th, shows a 0.7 ft swell from the E with a long period of 12 seconds, but that’s a whisper. Don’t hold your breath.
The bottom line: The only real window is Sunday morning, September 6th, and Monday morning, September 7th, for clean, small waves. The rest of the 16 days is a write-off. Nantasket Beach is a consistent spot, so it won’t stay this flat forever, but this stretch is a dud.
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.
Nantasket Beach is 8 km (5 miles) from the city of Hingham. If you plan a vacation in Massachusetts, look for hotels and other accommodation in Hingham. Hingham has rooms for a wide range of budgets as well as car hire and transport links.
