The Lowdown
Alright folks, let's call a spade a spade. I've looked over the next 16 days for Nahant Beach, and it’s a brutal run. There's nothing on offer worth paddling out for. We're staring down a long dry spell.
The water's sitting around 67°, which is a bit on the chilly side for this time of year, adding to the meh factor. You're looking at waist-high dribbles at best, mostly from the ESE or E direction, with short periods under 8 seconds. The combined energy never even gets into triple digits, topping out at 83 (mild). The wind is the real killer – onshore or cross-onshore most days, just chopping the heck out of whatever tiny bump there is. We get some clean offshore breezes on the 24th and 25th, but the swell is so small, it’s pointless.
For a beach break like Nahant, it's consistent, sure, but that doesn’t mean good. With these tiny, weak waves and onshore slop, this looks way more fun for a kite surfer than anyone on a paddleboard. There's no highlight, no saving grace in the whole two-week outlook. It's just flat or poor. Stick to the skatepark.

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.
