Alright folks, Rusty here. Let's talk about what we've got on the horizon. It's a real flat spell ahead, so don't be in a rush to grab your board.

For the next couple of weeks, Nantasket Beach is going through a major lull. Honestly, from now all the way through to Friday the 17th of July, we're looking at tiny, poor surf conditions. We're talking ankle-snappers at best, with waves barely hitting 0.7ft and weak energy levels. A lot of choppy, onshore wind days in there too, with a few clean mornings but just nothing to ride. It's a long stretch of nothing, nine days straight where it's just not worth paddling out.

Then, finally, something changes. On Saturday the 18th of July, we get a pulse of life. Saturday morning is the standout. Swell picks up to 5.2ft from the ESE, with a period of 7 seconds, and the energy kicks up to a moderate 233. The wind's out of the WNW at 9 mph, which is offshore, so it'll be clean with some shape. It's not the cleanest afternoon, but the morning window there is the only real shot you've got in this whole outlook. For a beginner, this is right on the edge at 5.2ft, but for anyone else, it'll be worth the wait.

So there you have it. All flat until the 18th, then one good morning. That's the story. Keep an eye on it.

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.
