The Lowdown
Alright folks, Rusty here. Let's not beat around the bush: the next couple of weeks are looking bleak for a proper surf. The charts are showing a whole lot of nothing for a while, and even when there’s a bump, the wind’s usually gonna mess it up.
The long and short of it is, we’ve got a serious dry spell on our hands. From now through the 4th of September, there’s just no surf to speak of. It’s a flat spell that’ll have you checking the buoys out of habit more than hope. A couple of times it looks like it might try and kick up, but the energy is weak and the direction is all wrong.
We finally see a little life on Saturday the 5th. We’re looking at Nantasket Beach, and it’s still pretty ordinary, but at least it’s something. That morning, you’ve got a touch of swell at 3ft from the ENE, and it’s holding together with a light cross-off breeze. The energy is still weak, reading 94, but it’s clean. The swell period is short, only 8 seconds, so it’ll be a bit soft and crumbly, but you can get a slide. The wave comment even says “surfable waves but very ordinary conditions,” which is about the best we’re gonna get.
That Sunday the 6th has a similar story, with 3ft from the ENE again and light winds. The energy is moderate at 114 and it's clean in the morning. By the afternoon, the wind goes totally glassy, which is a bonus, but the swell’s still nothing to write home about.
Monday the 7th, the swell bumps up a touch to 3ft, but the period drops to 7 seconds, so it’s gonna be a bit lumpy and disorganized. The morning is glassy with a light offshore breeze, and the energy is up to 177, which is the most we’ve seen all week. It’s the pick of the litter so far, but it’s still not great. Nantasket is an exposed beach, so a short-period ENE swell like this is going to be pretty walled-up and soft. It’s not going to be a rippable day, more of a longboard and log day for sure.
Then we go flat again through the 11th. Just a whole lot of nothing. The 12th of September shows a bit of a pulse again, but it’s still looking short-period and junky with no real quality to it.
So, here’s the bottom line. If you’re desperate, the early morning of Monday the 7th is your best bet. It’s got the most size and energy, and the wind is clean. Just don’t expect any gems. The water temp is sitting around 69°, which is about 1° warmer than usual for this time of year, so it’s still pretty comfortable in a springsuit. The rest of the window is a write-off. You might be better off waiting for the next system to come through and hoping for a better wind forecast.
This is Rusty, signing off. Keep your board waxed and your expectations low.

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.
