The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for Nantasket Beach over the next couple of weeks. I gotta be straight with ya – it's a grim stretch for paddle surfing. We've got a long, flat run ahead, so don't be in a hurry to wax up.
Right now and for most of the next week, it's just tiny, weak dribble. We're lookin' at wave heights barely kissin' 1ft to 3ft, with combined swell energies stuck in the weak zone (under 100). The wind is mostly a problem, swinging onshore or cross-onshore, choppin' up what little bump there is. This is beginner-level stuff at best, and honestly, mostly unsurfable. This poor run stretches all the way from now until the 20th of September.
Monday, 21st September is the first time we see a pulse of something that could actually move you. A 5ft NE swell rolls in, with the combined energy jumping to a moderate 226. The catch? Wind is light cross-onshore, so it'll have some texture on it but isn't blown out completely. Still, the wave comment calls it "marginal," so keep expectations low. After that, it drops back to flat, weak junk through the end of the month.
There is a little spike on Monday, 28th September with a 4ft to 4ft NNE swell and moderate energy (up to 182), but again, the wind is side or cross-onshore. It’s a beach break, so it's goin' to be a bit of a mess with that shorter 6-second period, makin' it a tough paddle for not much reward.
Honestly, for the entire 16-day window, there isn't a standout day. If you’re desperate, the 21st mornin' is your best bet, but it’s nothin' to write home about. For this area, a blank run like this isn't abnormal; the forecasts can change, but right now it looks like it's time to tune up your gear and wait.
Stay patient, crew.

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.
