The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this upcoming stretch for Nantasket Beach is a tough one. We're looking at a solid 16-day window, but the honest truth is this forecast is a dud. There's not a single good surf option in the whole period. The first couple of days, July 28th and 29th, have a little bit of swell, but it's messy, wind-blown junk. The combined energy is weak, barely cracking 40 (40) and 33 (33) on those first two days, and the wind is a cross-shore or cross-onshore mess. It's a flat spell, plain and simple.
We start off on Tuesday, July 28th, with a weak 2ft swell from the east, but that southerly wind at 16 mph is just going to tear it apart. The water is sitting at 64°, which is a solid 4° colder than normal for this time of year – that's a notable chill, so you'll want a thick wetsuit if you're even thinking about it. The swell period is a short 7 seconds, so there's no power behind it. By Wednesday morning the 29th, we get a little bump to 3ft, but again, it's onshore and choppy. The energy is low (33). The best looking day in the whole run is probably Thursday, July 30th afternoon, when the swell hits 7ft from the NE and the energy jumps to 343 (343). That's a moderate amount of energy, but it's still cross-onshore at 16 mph, creating a lumpy, choppy mess. For a beach break like Nantasket, that kind of wind and size is more of a kite-surfing session than a paddle-surfing one.
After that, it just fades away. From Friday, July 31st, all the way through to August 12th, the swell drops to 2ft or less, with energy levels barely registering. The wind does go light and offshore a few times, like on August 3rd, but with a 0.3ft swell, it's a lake. There's a gap of over a week with absolutely nothing rideable. The onshore wind and the tiny swell are a persistent problem. The forecast is what it is, and this area can go through blank runs like this. Keep your eye on the forecasts, because it tends not to stay this poor forever, but for now, the boards are staying in the shed.
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.
