The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook for Nahant Beach is a tough one. We’re looking at a long stretch of minimal, weak swell and mostly ordinary conditions, so don’t get your hopes up for any epic sessions. The best we can hope for is a few small windows of clean, rideable waves, but nothing that’ll get the heart pumping.
The forecast starts on Tuesday, 25th August with a tiny 1.3ft swell from the SE, period of 7 seconds, and weak energy (25). The water temp is sitting at 67.6°, which is pretty normal for this time of year. Despite the offshore wind, the surf is just too poor to bother.
We’ve got a real dry spell running from the 25th of August all the way through to the morning of Wednesday, 9th September. For nearly two weeks, the swell stays tiny, rarely cracking 2.0ft, with periods mostly under 10 seconds and energy readings that are mostly weak (less than 100). There are a few mornings with glassy or clean conditions, like Wednesday morning, 26th August, with a glassy 1.3ft ESE swell, but that 9-second period and the total lack of energy (33) mean it’s just not going to break with any push. The afternoons get choppy and messy with onshore breezes.
The only real glimmer of hope comes on the morning of Wednesday, 9th September. We finally see a bump to 2.3ft from the ESE, with a period of 8 seconds, and combined energy climbing to 75. The wind is from the WNW, 9 mph, making it a clean cross-off. The wave comment says “surfable waves but very ordinary conditions,” which is the best we get. It’s still small, not a standout by any means, but if you’re desperate for a paddle, this is your window. The afternoon stays similar with a bit more energy (114) but stronger winds from the NW making it less appealing.
Overall, this is a bleak run for Nahant Beach. The swell is too small and weak for most, and the consistency is poor. It’s the kind of stretch where you’re better off waiting for the forecast to change. Hang tight, folks.

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.
