Alright, let me tell you how it’s looking for the next couple of weeks. It’s a pretty quiet picture for the most part, so don’t go getting your hopes up too high.
Right now, we’ve got a little bump on Thursday morning with some knee-high, weak easterly swell around 3 ft and a short period of 7 seconds. The wind is light offshore from the west, so it’ll be clean. But honestly, the energy is really weak (69) and the waves are just ordinary. Nothing to write home about.
From Thursday afternoon all the way through to the end of July, it’s a long, flat stretch. The swell drops right off, mostly below 2 ft, and the wind is all over the shop – onshore, cross-shore, you name it. There’s really nothing worth paddling out for. The water temp is about average for this time of year at Nantasket Beach.
The only flicker of something comes right at the very end of the outlook, on the 24th of July, Friday morning. We’ve got a tiny 1 ft swell from the southeast, but it’s glassy – dead calm wind. The energy is still weak (25) and the period is short at 6 seconds. It’s a long shot, but if you’re desperate for a clean, tiny wave, it might be the only chance.
Overall, it’s a poor run of surf. If you’re a kite surfer, the choppy, onshore days mid-week might look more interesting than paddle surfing. For the rest of us, it’s a waiting game.

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.
