The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next 16 days at Nantasket Beach are looking pretty flat. We’re in for a dry spell, so temper those expectations.
Starting off now, we’ve got a long stretch of nada. From Saturday, August 1st all the way through to the morning of Wednesday, August 13th, there’s just nothing worth paddling out for. You’ll see tiny waves here and there, mostly between 0.3ft and 2ft, but they’re weak – the energy never gets out of double digits, topping out at a measly 33 (combined energy). Winds are a mixed bag of cross and cross-off, but with no swell, it doesn’t matter. The water temperature is sitting at 65°, which is a solid 4° colder than usual for this time of year – that’s a bit nippy, so you’ll want a thicker suit.
The one tiny glimmer in this whole outlook comes on Thursday morning, August 13th. We’ve got a glassy morning with 1ft of swell coming from the ESE, with a period of 5 seconds. It’s a windswell, short and weak – energy is only a 12. But it’s glassy. For a few hours, it might be clean enough to get a fun little log out on a high tide. But don’t call it a standout; it’s just the only thing that’s not a total write-off. After that, it’s right back to flat and calm right through to Sunday, August 16th.
Honestly, this is a classic summer flat spell for Nantasket. If you’re desperate, keep an eye on that Thursday morning, but otherwise, it’s a good time to clean the wax off your board and wait for the next storm.
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.
