The Lowdown
Alright folks, it's Rusty here, and I'm looking at the next 16 days for Nantasket Beach. I gotta be straight with you – it's a tough stretch. We've got a whole lot of flat, weak, and sloppy conditions ahead. The first real window of interest doesn't even show up for a while.
The 16-day window kicks off with absolutely no surf to speak of for a solid two weeks. There's a long, empty gap from now all the way through the early part of August. The water is currently sitting at 65°F, which is a bit colder than usual for this time of year, so don't expect a warm bath.
Looking at the data, we finally see a tiny pulse of energy late in the game. The first and only real chance of anything rideable appears on Wednesday, August 12th, into the 13th. A small, short-period swell from the NE tries to push in, with mixed wind conditions. This is really a last-resort kind of session.
The standout, and really the only option, is right here at Nantasket Beach. By Wednesday afternoon the 12th, we might see a small, bumpy 3ft wave from the NE, with a short period of 5 seconds. The combined wave energy is weak at 60. It's not going to be pretty, but it's something. The wind will be onshore from the ESE at 12 mph, so expect messy, choppy conditions. It's not a beginner's wave – it's more of a survival mission for the dedicated.
By Thursday morning the 13th, the swell drops to 2ft from the ENE and the wind swings southerly, creating a messy cross-shore chop. This stretch is really only going to appeal to folks who absolutely have to get wet, or maybe it's more interesting for kite surfing than paddle surfing given the onshore wind and weak, choppy surf. For the rest of us, it's a time to work on the board collection.
Stay patient, folks. The ocean will come back around.

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.
