The Lowdown
Alright folks, Rusty here. Let's have a look at what's ahead for the next couple of weeks.
First off, I gotta be straight with you – this is a tough stretch. Looking at the whole 16-day window, there's nothing to get excited about. The numbers are flat, the wind is messy, and the energy just isn't there. We've got a long, dry gap ahead with no real surf on offer. For Nahant Beach, a spot that's already a beginner-friendly, exposed beach break, the conditions are just poor right through. From late August all the way to the end of the forecast period in early September, the swell stays tiny, barely scratching above 2 ft at its best, and most days are sitting around 0.7 ft to 1 ft. The combined energy is weak, too – I'm seeing values like 33, 51, even as low as 6, all under that 100 mark, so there's just no push.
The wind is the real killer. For the first few days, it's cross-on or onshore from the northeast and east, which is about as unkind as it gets for that beach setup. The water temp is around 69°F, which is pretty much average for this time of year, nothing weird there. But the short, weak periods – mostly 6 to 8 seconds – mean the waves are just crumbly and fat. Even when we get a glassy morning on the 28th, the swell is only 1 ft, so it's barely a ripple.
This is one of those times where you might be better off with a kite if the wind picks up, because the paddling just isn't going to get you anywhere fun. This kind of blank run isn't unusual for the area. It looks like a long, quiet spell. We'll see if the forecasts shift, but as it stands, keep your board waxed and your expectations low.

Information about the Nahant Beach Surf forecast
The above surf forecast table for Nahant Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nahant Beach can be found by selecting the local surf guide option on the grey menu. Our Nahant 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 (Nahant 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 Nahant 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.
