The Lowdown
Alright, let’s get into it. Rusty here, lookin’ at what’s on offer for Nantasket Beach over the next couple of weeks. Gotta be straight with ya – it’s a lean stretch, no two ways about it. The first real chance of anything even remotely worth paddlin’ out for doesn’t show up until Saturday the 19th, so we’re talkin’ a solid week of flat, choppy, or just plain poor conditions. That’s a long gap of nothin’ to get excited about.
Let’s run through it. Friday the 11th through to the 18th is a write-off. Tiny swell, ugly winds, and the wave comment spells it out: “poor surf conditions” across the board. You get a bit of glass on Friday afternoon the 11th with a 0.3 ft easterly at 11 seconds, but there’s no energy behind it – combined swell energy of just 4. That’s a lake, not a surf break. The days just drag on with choppy cross-onshore slop and weak little windswells. Not worth your time.
Then on Saturday the 19th, we finally get a pulse. Morning brings a 4 ft swell from ENE at 7 seconds, combined energy of 104 – that’s moderate, at least somethin’ to work with. The wind’s a light cross-offshore from the south at 3 mph, and it’s rated as clean. The wave comment calls it “surfable waves but very ordinary conditions,” and that’s about right. It’s not gonna blow your mind, but for Nantasket Beach, it’s the best we’ve seen. The afternoon drops off quick, so hit it early if you’re desperate for a paddle. Crowds can show up here, so don’t expect to have it to yourself.
Beyond that, the rest of the window is a mess again. Monday the 22nd and Tuesday the 23rd tease with knee-high 2 ft-3 ft easterly swells, but the wind is onshore or cross-onshore, makin’ it choppy and uninviting. The combined energy stays under 104, so it’s weak. Thursday the 24th and Friday the 25th get blown out by strong northerly and northeasterly winds, 16-22 mph, with lumpy cross-chop. Not your day.
The one flicker of hope comes on Saturday the 26th – that’s over a week away, so take it with a grain of salt. Morning shows a 2 ft long-period groundswell from the east at 14 seconds, combined energy of 208 (moderate), with a clean cross-offshore breeze from the southwest at 12 mph. That period is long enough to wrap in nicely at a beach break like Nantasket, but it might also make it a bit straight, so don’t expect perfection. The wave comment says “marginal surf forecast or questionable tide conditions,” which means it could be worth a look if the tide lines up. Promisin’, but not guaranteed.
If you’re a beginner, that 4 ft on the 19th is fine, but the 2 ft on the 26th is small and meek. Nothin’ here gets over 5 ft until the 18th, when we see a 7 ft NE swell – but that day is plagued with onshore wind and a “poor surf conditions” label, so it’s lumpy, messy, and better suited for a kite board than a paddle board. Stay patient, keep an eye on the forecasts, and don’t hold your breath for any standouts.
Rusty, out.

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.
