The Lowdown
Alright folks, Rusty here. Let’s get into it.
Well, to be honest, looking at the next 16 days, it’s a tough one for Nantasket Beach. We’re staring down a long dry spell. The first few days are flat and messy, and the pattern doesn’t really change. The good news is that the swell direction is mostly from the East and Northeast, which is what this spot loves, but the size just isn’t there.
The biggest issue is we’ve got a long gap of nothing. From Friday, July 31st, right through to the morning of Monday, August 10th, there’s nothing worth paddling out for. The waves are tiny, with the biggest swell height being just 2 ft, and that’s accompanied by cross-onshore winds. The combined energy during this stretch is a sad 28 (weak energy) at best. It’s just not happening.
The first real glimmer of hope comes on Monday, August 10th. The afternoon shows a little pulse: 2 ft of East swell with a 12-second period. That period is a solid groundswell, and the combined energy jumps to 80 (moderate wave energy). The winds are offshore and clean. It’s still small, but it’s the best of a bad bunch. The consistent nature of the break means it might just offer a few fun, clean lines, though crowds are possible here.
Then it fades again. The next week is filled with more of the same: tiny, weak, and often messy. The morning of Thursday, August 13th, offers a rare moment of glassy conditions with a tiny 0.7 ft East swell, but it’s barely a ripple. The combined energy is only 9 (weak energy).
Forget about any standout sessions. Nothing here gets above 2 ft, and the best winds are just “clean” or “offshore,” but the swell is too weak to do anything with. The water temp is sitting at 66°F, which is a bit colder than usual for this time of year. If you’re a beginner, this is a total no-go. If you’re an expert, you’re better off staying home.
This is a classic Nantasket summer lull. It’s flat, and it’s likely to stay that way. Forecasts can change, but for now, leave the boards in the car.
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.
