The Lowdown
Alright, grab a coffee and let me talk you through the next couple of weeks at Nahant Beach. It’s a pretty grim stretch ahead, I’ll be straight with you.
Right now, through the rest of August and into the first week of September, we’re looking at a flat spell. The swell is tiny, barely a ripple, and the wind is all over the shop – mostly onshore or cross-shore, keeping everything messy. There’s a solid 10-day gap here with no real surf on offer. The water is sitting at 68°F, which is about average for this time of year, so no surprises there.
We do get a tiny flicker of life around Wednesday, 26 August. The swell pushes up to 4ft to 4ft from the northeast, and the wind goes clean, swinging cross-offshore from the northwest to west-northwest. The combined energy hits 109 and then 134, so it’s got a bit of grunt. But even then, the wave comment says “surfable waves but very ordinary conditions,” and the rating only scrapes a 1 out of 10. Honestly, it’s not worth paddling out for. The swell period is short, around 5-6 seconds, so the waves will be weak and crumbly, and the direction is ENE, which isn’t ideal for this spot that prefers ENE.
Forget about any standout sessions here. The whole 16-day window is a write-off. If you’re desperate, that Wednesday 26 August is the only day with anything rideable, but it’s more of a “I’m bored and want to float around” kind of day. Don’t get your hopes up.

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.
