The Lowdown
Alright, surfers, Rusty here. Let’s get real about the next couple of weeks at Nahant Beach. I’ve got to be straight with you – this is a tough stretch. The forecast is showing a long, dry spell with hardly any swell to speak of.
We’re looking at a solid 16-day window, but it’s a barren one. The first proper surf doesn’t show up until Thursday, August 14th, and even that’s a bit of a mess. So, we’re talking about a gap of nearly two weeks with nothing worth paddling out for. The water temp is sitting at 66°, which is a bit colder than normal for this time of year.
Let’s run through it. From July 30th right through to August 13th, the swell is tiny. We’re talking knee-high stuff at best, with wave energy readings like 51 (weak) and often slipping into single digits. The wind is a constant problem, too, often cross or cross-on, and the one time it goes clean offshore, there’s no wave to use it. It’s a real bummer. The only flicker of hope is a little 1ft SE swell on Tuesday, August 4th, with a gentle offshore wind, but it’s too small to get excited about.
Now, the standout – and I use that term loosely – is the morning of Thursday, August 14th. We see a pulse of NE swell pushing 4ft, with a period of 6 seconds. The combined energy jumps to 107 (moderate), which is the biggest number we’ve seen. But the wind is a cross-on NE breeze at 12 mph, which will have it chopped up and messy. It’s the best on offer, but it’s not pretty. The afternoon of the 14th shows a bit more size, up to 5ft, with the energy climbing to 231 (moderate), but the wind is still cross-on and ruining it. For a spot that’s already exposed, this is more of a kite-surfing setup than a clean paddle session.
Honestly, this whole run looks more interesting for kite surfers than for us. The swell is too small and the wind is too wrong for most of it. A blank run like this is normal for the area when the patterns shift. Forecasts can change, so keep an eye on it, but don’t hold your breath.
Rusty.

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.
