The Lowdown
Alright folks, Rusty here. Let’s be straight with you – we’ve got a long, flat stretch ahead for Nantasket Beach. There’s no good surf on the table for the next 16 days, so don’t be in a rush to grab your board.
The first solid chance at a wave doesn’t even show up. From the 1st of September through the 16th, we’re looking at a near-constant run of tiny, weak slop. The swell energy is almost non-existent, with readings like 3, 6, and 25 – that’s barely a ripple. The biggest combined energy we see is a paltry 61 on the morning of the 6th, with a messy 3ft swell from the NE and a period of 6 seconds. That’s not worth paddling out for. Most days, the swell is around 0.3ft to 2ft, with periods that are either short or just average. The wind is a mixed bag, but it doesn’t matter – there’s simply nothing to ride.
The water temperature is sitting around 69°F on the 1st, which is about 2°F warmer than average for this time of year. That’s a nice detail, but it won’t help the surf.
This is just one of those stretches where the ocean takes a breather. A blank run like this is more normal for the area than you’d hope, but forecasts can change. Keep your eyes peeled, but for now, it’s a no-go.
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. 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.
