The Lowdown
Alright folks, Rusty here. Let me break down what's on the cards for our local stretch.
To be straight with you, the next couple of weeks are looking pretty grim. We’ve got a long stretch of small, weak surf with wonky wind for most of the period. The water is sitting at 67°, which is a bit colder than normal for this time of year – you’ll feel that slight chill.
The first real chance of anything rideable doesn't even show up until Sunday, August 23rd. That morning, Nahant Beach might cough up a few small 3ft waves from the ENE with a short 5-second period. The combined energy is weak at 74, and the wind will be a light cross-offshore from the NNW, keeping things clean. It’s surfable, but very ordinary. That afternoon, the wind swings around and kills it.
Then there’s a big gap. The next morning worth mentioning is Monday, August 24th. The swell drops to 1ft from the ESE, but the wind goes offshore from the WNW with a gentle breeze, making it clean. It’s still tiny, and the energy is a paltry 27. Not worth a paddle.
We get a bit of a bump in size on Thursday, August 27th. A short-period 6ft to 6ft pulse from the E and NE rolls in, with moderate cross-shore wind. The energy jumps to 186 in the morning and 309 in the afternoon, but with that wind and messy period, it’s labelled as poor conditions. That’s about as big as it gets, and it’s not good.
After that, it’s back to small, poor surf for the rest of the run into early September. The only other moment that’s even worth a mention is Sunday, August 30th. The morning will be glassy with 3ft waves from the NE, but the period is a short 5 seconds, and the energy is only 55. It’s rideable, but nothing special.
Honestly, this is a tough outlook. There’s no standout window, no quality swell direction for the break's optimum ENE, and the winds are too often onshore or cross. Nothing here is worth getting excited about. Hopefully, the forecasts change, but for now, it’s a flat spell.
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.
