Alright, grab your boards and listen up. Rusty here. I've looked at what we've got, and to be straight with you, it's a grim picture for the next two weeks. There's a big, boring gap at the start with nothing worth paddling out for. The first hint of anything rideable doesn't show up until Wednesday, July 22nd.
Nantasket Beach is our only spot on the menu, and for the first week and a half, it’s a ghost town. The swell is tiny, or the wind is junk. Don’t even bother checking the cam until July 22nd.
Then, on the morning of Wednesday, July 22nd, we finally get a little pulse. We're looking at a 5ft swell out of the east, with a short period of 6 seconds. The combined energy is moderate at 188, but that's the biggest we see in this whole outlook. The morning has a cross-offshore breeze from the NNW, which will keep the surface clean. It’s a bit of a relief after all that nothingness.
Now, 5ft sounds okay, but that short period, under 8 seconds, means it's going to be a bit dumpy and weak. It's not beginner-friendly at that size with a short period. The afternoon on the 22nd turns onshore and messy, so your window is tight. The 23rd is a step down and nothing special.
Truth is, this is Nantasket we're talking about—a consistent beach break, so this drought is unusual. It won't stay this dead forever. But looking at the data, the only real standout, if you can even call it that, is that Wednesday morning session on July 22nd. It's not world-class, but it's the only wave in town.
Stay patient.

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.
