The Lowdown
G'day, Rusty here. Let’s be straight with you – the next 16 days at Nantasket Beach are a tough one to call. There's a long quiet stretch ahead, don't expect much to get the heart racing. The water temp is sitting right on average for this time of year at 68°.
First up, we're looking at a real flat spell. From Tuesday, the 25th of August, right through some of the first week of September, the waves are tiny – mostly around 0.3ft to 2ft. The swell direction is coming from the east and southeast, which is okay for the break, but the energy is weak, with combined energy values barely hitting 47 (moderate energy) at best, and often down around 7 (weak energy). There's a few mornings with clean, glassy conditions, like Wednesday the 26th and Saturday the 29th, but with swell that small, it's just not worth paddling out for. The wind does offer some light offshore and glassy windows, but the lack of height means you're just floating.
There is a bit of a lift around the 2nd and 3rd of September. Wednesday morning, the 2nd, shows a bump up to 2ft from the NE, but the period is a short 4 seconds and the wind is cross-onshore and choppy (combined energy 29 – weak). The following day, Thursday the 3rd, has a similar 2ft from the ENE with a 5-second period, cross-onshore breeze, and the energy is 38 (weak). It’s messy, short-period windswell, not the kind of surf that puts a smile on your face. The setup is a beach break, so with that poor quality and wind, it looks more interesting for kite surfing than paddle surfing.
The best chance in the whole window looks like it could be on Wednesday the 9th of September. There's a jump to 2ft from the east, with a period of 8-9 seconds, and the combined energy reaches 88 (moderate energy). The wind is forecast to be a clean cross-offshore from the WNW and NW. That's the cleanest window we get, but it’s a long way out, so treat it as promising but uncertain. Still, with only 2ft on offer, it’s small even for an intermediate. The crowds can be around sometimes, but the conditions might be worth a look if you're desperate.
Honestly, this is a blank run. It’s one of those periods where the ocean just goes to sleep. Forecasts can change, but as it stands, there’s no standout day. The best advice is to keep an eye on that Wednesday the 9th, but don't hold your breath.
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.
