The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for Nantasket Beach.
Honestly, the next week and a half is a bit of a tough watch. We’ve got a long stretch of small, messy, onshore junk with no real energy. It’s not until the second week of September that things start to flirt with something worth a paddle.
The first real flicker of hope comes on Thursday, September 3rd. The morning’s still a write-off, but by the afternoon that wind swings to a light north-northwest, giving us a clean, cross-off breeze. The swell is tiny though, only 3ft out of the east-southeast with a short period of 6 seconds. It’s weak—combined energy is just 71—so you’re looking at knee-high slop, but at least it’ll be clean. Not a standout, just a glimmer.
We skip through a few more flat or poor days, and then something catches the eye. Monday, September 7th. That’s the real standout. The morning and afternoon both serve up clean conditions with a light west-southwest wind, going offshore in the afternoon. Swell is a modest 3ft to 4ft out of the east-northeast, period bumping up to 10 seconds—real groundswell energy. Combined energy sits at 265, which is moderate. The water temp is running about 69°, which is a touch warmer than normal for this time of year, so you won’t mind a bit of a wait between sets. The sets will have some push, but with that period, it’s best for a reef or point, and Nantasket Beach is a beach break, so expect it to wall up a bit. Still, with light winds and clean faces, that’s your best window for a proper session. Crowds are sometimes an issue here, so expect company.
The following days fade back into small, weak, and clean but lifeless conditions. Tuesday the 8th has some clean 3ft waves but the energy drops right off to 84. After that, it’s mainly flat or choppy until the end of the forecast window.
So, bottom line: you’ve got a long dry spell, then a promising Monday, September 7th with clean 3ft to 4ft east-northeast groundswell and offshore winds. That’s the one to circle. Everything else is pretty much a skunk.
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.

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.
