Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Let's just get it straight: the next 16 days at Nantasket Beach are looking pretty bleak for any real surfing. There are no good surf options on the table right now. This is a blank run, plain and simple, and honestly, for this stretch of coast, that's not totally unusual when the conditions just don't line up.
We're looking at a long gap here. From today through most of the period, we're stuck with tiny, weak swell and nearly constant cross-onshore winds that just chop everything up. The few times the wind goes offshore or cross-off, the waves are practically flat.
The only time we see even a pulse of energy is around Tuesday, July 7th, when the swell bumps up to 6ft from the E/ENE. The combined energy hits 598 (moderate) and 404, but the period is a short 7 seconds and it's blowing 18-21 mph cross-onshore. The conditions are rough. That size with those onshores makes it a messy, lumpy affair that's better suited for kite surfing than a paddle session.
After that, it fades back to tiny, weak stuff. There are a few clean windows from Thursday, July 9th through the weekend, but the swell drops to 2ft or less. Not worth the wetsuit.
So to sum it up: there isn't a single standout in this forecast. The whole 16-day run is a write-off. Keep the board in the car for a better day down the road. Forecasts can change, but for now, this stretch looks quiet.

A general guide to surfing at Nantasket Beach can be found by selecting the local surf guide option on the grey menu.

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.
