The Lowdown
G'day, I'm Rusty. Let's have a look at what's shaping up for Nantasket Beach.
Honestly, if you're hanging out for a paddle, you're gonna be waiting a while. The next week and a half is a write-off. There's tiny, weak dribble with dodgy wind setups. We're looking at a big gap with no real surf on offer until we get into early September.
The Outlook:
Right now through the end of August and into the first few days of September, it's flat or close to it. We've got nothing but poor surf conditions day after day. The water temp is sitting around 69°F, which is about average for this time of year.
We finally see a pulse of swell pop up on Saturday, September 5th. A NE windswell builds to 5 feet, but it's short period at 7 seconds and the wind is messy. The combined energy jumps up to 260 (moderate) on the morning, but it's accompanied by a cross-shore breeze. That's a lot of energy for the size, but the wind will make it a bumpy, lumpy mess. By the afternoon, the onshore kicks in and it gets worse. Without good wind, the size is just a messy shore break. With that amount of energy and poor surf quality in a beach setup, this looks more interesting for kite surfing than a paddle surf. Sunday the 6th sees even more energy, 435 on the morning, with a strong cross-shore wind. That's over 8 feet, so it's expert territory, but the onshore wind on the afternoon will absolutely destroy it.
The standout in this whole 16-day window is a brief moment on Monday, September 7th. The swell drops back to 3 feet from the ENE, but the period stretches out to 10 seconds, giving it some real push. The combined energy is 141 (moderate). The wind is light NE, just a cross-on breeze, so it won't be perfect, but it's the cleanest shot we get at a real wave. It's not a standout by any stretch, it's just the only game in town. The swell direction from the ENE isn't the ideal NE for the break, but you'll get some fun little runners. Nantasket Beach can be crowded, so just be aware you won't be alone.
After the 7th, it drops right back to flat, tiny, and weak through the 12th. A blank run like this is normal for the area when there's no proper groundswell on the horizon.
Fact is, there isn't a single true standout session here. The best on offer is that Monday morning, September 7th – a small, clean-ish window with a bit of period.
Rusty.

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.
