The Lowdown
Alright, let's get into it. Rusty here.
First off, I gotta be straight with you – we are looking at a real lean spell for Nantasket Beach. There's nothing worth paddling out for right now and it's going to be that way for a while. We’re talking about a solid stretch of over a week with basically nothing on offer, just knee-high dribble and onshore junk. The first glimmer of anything surfable doesn't show up until Saturday, the 19th of September, and even then, it's not much to write home about.
The water is running about average for this time of year, so no surprises there.
So, for the first ten days or so, it’s flat. Forget about it. Then on Saturday morning, the 19th, we finally see a little pulse of life. A 4 ft swell out of the NE with a short, weak period of 6 seconds. The combined energy is only 121 (moderate wave energy), so it's not going to have much push. The real kicker is the wind: it’s glassy. That could make for some clean, soft little rollers. This is about the only true standout in the whole 16-day window, and it's only really for the morning session before the wind swings onshore and chops it up. The NE direction isn’t exactly the optimum for this spot, but it's exposed to it, so it'll wrap in a bit.
Being a consistent, exposed beach break, it won't stay flat forever, but this window is looking pretty poor overall. The only other small bit of hope is Friday the 18th in the morning with glassy conditions, but the swell is a pathetic 2 ft.
Honestly, with the combined energy for most of this being in the weak range (under 100), and the swell directions being all over the place, this isn't shaping up for much more than a recovery paddle. If you're desperate for a surf, Saturday the 19th morning is your only real shot, but keep your expectations real low.
Rusty.

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.

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.
