The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Nantasket Beach over the next couple of weeks. Gotta be straight with you – it’s a pretty lean run.

For the first week, from Friday the 28th of August right through to Thursday the 3rd of September, there’s just no surf worth paddling out for. We’re talking tiny waves and poor conditions day after day. It’s gonna be a long, flat stretch. You’d be better off finding something else to do.

Now, things try to get a little interesting as we move into late in the period, but even then, it’s only a short window. The only real highlight shapes up on Saturday morning, the 5th of September. For a few hours we could see some fun waves. Nantasket Beach will be picking up a chest-high, 4ft swell from the ENE. That’s a groundswell with a solid 10-second period, so there’s some decent energy behind it (346). The wind is forecast to be glassy early – that’s a huge plus for clean, smooth faces. This is the standout of the whole outlook, but it’s a long way off, so treat it as promising but not set in stone.

The rest of that weekend and into the following week settles back down into small, ordinary stuff with only marginal conditions. There’s a bit of leftover ENE swell on Sunday the 6th, around waist to chest-high with moderate energy, but the onshore breezes will mess it up.

Overall, I gotta say, for a spot this exposed to the NE swell direction, we’re just not getting the love this time. Conditions look better for a casual paddle than a proper surf session. Nothing to get excited about until that Saturday morning window, and even then, keep your expectations in check.

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.
