The Lowdown
Alright, folks, Rusty here. Let's be honest about what we're looking at for the next couple of weeks. It is a tough stretch for Nantasket Beach. The immediate outlook is a bust, and we're staring down a long, dry spell with very little to get excited about.
The water is sitting at 65°F, which is a bit colder than we'd expect for this time of year. That's a bit of a bummer to start.
The first few days are a write-off. Through Wednesday the 30th, we've got onshore winds, crummy wind states, and only small, weak, short-period windswell. The combined energy is barely registering (31 to 94), and the wave comment is screaming "poor surf conditions." It's not worth paddling out for.
Thursday the 31st through the weekend is more of the same. The swell stays tiny, mostly under 3ft, with weak energy (53 and lower). The wind does improve a bit, with some light breezes and even a glassy morning on Saturday the 1st, but there's just no wave to ride. The period is all over the place, from a short 4 seconds to a 10-second groundswell, but the height is essentially flat.
After that, the bottom completely falls out. From Sunday the 2nd all the way through Thursday the 13th, the swell drops to a pathetic 0.3ft to 1ft. The combined energy is in the single digits or low teens. There are some clean mornings with glassy conditions (like the 7th and 13th) and offshore winds, but you can't surf on wind alone. The period does climb to 9-10 seconds on some of these days, suggesting a long-period groundswell, but it's ghosting – there's no height to go with it.
There is no standout day. There is no best on offer. The entire 16-day forecast is a painful gap. There are zero good surf options in this window. The only thing Nantasket has going for it is that it's a consistent beach break, so it tends not to stay this poor for long, but for now, leave the boards in the shed. The only thing that might be interesting here is for the kite surfers, as the steady onshore winds on a few days could be more their game than ours.
This is Rusty, signing off.

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.
