The Lowdown
Alright folks, Rusty here with a look at what’s coming up for Nantasket Beach over the next couple of weeks. Gotta be straight with you – this stretch is lookin’ pretty quiet.
For the full 16-day window, the swell is just too small and weak to get excited about. The combined wave energy barely breaks into double digits most days (often sitting below 25), and the heights are hovering around that ankle-to-knee high mark, 0.3ft to 2ft. That’s not enough push to get a proper ride, regardless of the conditions. The water temperature is a cold 63°, which is a whopping 5° colder than normal for this time of year – a real shock to the system if you’re brave enough to paddle out.
Wednesday the 22nd is a write-off. We’ve got a weak 1ft SE swell with a short 5-second period, and a cross-off wind that keeps the surface clean, but there’s just no juice in the water. Same story into Thursday the 23rd – a bit of a long-period SE swell at 10 seconds, but the swell height stays at 1ft, and the wind swings cross-on, putting a bit of texture on the surface. The weekend of the 24th and 25th is the same old story: tiny surf from the east and southeast, with onshore winds making it choppy and messy.
We’ve got a few days in a row here where it’s basically flat. The 26th, 27th, and 28th offer nothing over 1ft, and the wind is mostly cross or cross-on, so don’t bother. By the 29th, we see a clean 2ft E swell on Wednesday morning with a cross-off wind, but at 6 seconds, it’s just a weak, short-period bump.
Thursday the 30th of July is about as glassy as it gets in the morning – wind is glassy, and we have a 0.7ft swell with a 10-second period. But it’s so small you could count the ripples. That theme of tiny, weak surf continues right into the first week of August. The best looking morning session might be Monday the 3rd of August, with a 1ft SE swell and clean conditions from a light offshore wind. Again, it’s small, but at least it’s clean. The wind stays favorable on Tuesday the 4th with glassy conditions in the morning on a 1ft swell.
To be honest, there’s no standout here. The swell is just too small across the board. The combined energy values rarely top 30, meaning there’s no power in the water for paddle surfing. For the first week it’s a complete bust, and the second week only offers tiny, clean windows. This is one of those stretches where you’re better off doing something else or just staring at the horizon.

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.
