Alright, grab a coffee, this is a tough one.

Look, I’m gonna level with you. We’re staring down a long, dry spell here at Nantasket Beach. It’s not looking great for the next couple of weeks. For the next week or so, we’ve got nothing worth paddling out for. The only real flicker of life comes on Thursday the 9th, with a little 3 ft wave from the east, but with a short period of 7 seconds and weak energy (69), it’s just not going to hold up. The morning wind is light offshore though, so it’ll be clean, but it’s tiny.

After that Thursday morning, it’s a ghost town. We’re looking at a solid stretch with no real recommendations all the way through until the end of the third week of July. You’ll see small, weak bumps here and there, but nothing with enough push or the right wind to get excited about. The water is sitting at 68°, which is a touch warmer than we’d expect for this time of year, but that’s small consolation when there's no surf.

The second week doesn't offer any hope either. It's all small, weak, and messy. The swell energy is in the single digits most days – that's a dead ocean. We get a couple of glassy mornings on the 16th and a few days with a light offshore wind right at the end, but the swell just isn't there to back it up. It’s flat.

Honestly, for a beach that's generally consistent, this is a rare run of poor conditions. Don't bother digging the wetsuit out yet. Forecasts can change, but right now, this is a blank run. If the wind kicks up, the setup might look more interesting for kite surfing than paddling, but for us surfers, it’s a no-go.

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.
