The Lowdown
Alright folks, it’s Rusty here. Let’s be straight with you. Looking at the next couple of weeks, it’s a pretty flat and quiet picture for Nantasket Beach. We’ve got a long stretch of small, weak surf ahead, and it’s going to take a while before we see anything that gets the heart racing. The first week is basically a write-off for any real waves, so don't get your hopes up.
The water temp is sitting at 71.1°F, which is right around average for this time of year, so no surprises there. The first few days are looking pretty sad, with waves barely breaking a few inches. There’s a moment on Thursday the 13th where the wind goes glassy offshore, but the swell is still essentially nothing. It’ll be clean, but there’s nothing to ride. We see a tiny bump of energy on the 15th, but it’s still well under a foot, and that’s being generous. The long period swells we see early on aren't doing us any favors either, as the energy just isn't there.
The following week, things pick up a little, but it’s still far from good. The swell direction shifts around from the east to the southeast, and while the energy readings start to climb, the wave heights remain stubbornly small. We're looking at ankle-biters at best. The wind does go offshore and clean on the 20th and 21st, but with a swell that’s barely 1ft, it’s still a no-go for a proper surf. It might be a nice day to sit on the beach and watch the water, but not much else.
The best of the bunch, if you can call it that, looks like the morning of Sunday the 24th. We’ve got a 3ft swell from the ENE with a period of 5 seconds. The energy is moderate, and the wind is a light cross-shore, so it might be semi-rideable for the most desperate among you. It’s not going to be pretty, and the short period will make it a bit fat and messy. Don't expect any standouts here. This is a classic case of a long, flat spell. The beach is a consistent break, so it tends not to stay this poor for long, but this forecast is what it is. The potential is there for a change, but right now, it’s a whole lot of nothing.
There's a lot of small, weak surf and poor conditions on offer. If you're a beginner, you might find a few whitewash waves to mess around on, but for anyone else, I'd say keep the board in the car. The setup looks far more interesting for a kite surfer than a paddle surfer on most of these days, especially when the wind picks up.
Stay patient.

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.
