The Lowdown
Alright, let’s talk in feet and degrees for you. I’m Rusty, and I’ve seen Nahant Beach go through every mood. For most of this stretch, it’s been snoozing. We’re looking at a big dry spell from Tuesday, July 14, all the way through most of Friday, July 24. Days and days of knee-high or smaller slop, mostly with short-period waves that just don’t have any grunt. A few glassy mornings pop up on the 17th and 18th, but with waves barely 0.3 ft and combined energy in the single digits (7-8), it’s basically a lake.
The one moment worth circling on your calendar is Saturday morning, July 25. The swell finally shows up, pushing to about 3 ft from the ESE, with a 12-second period – that’s real groundswell with actual shape and push. The combined energy jumps up to 305, which is a solid, moderate punch for this break. And the wind? Dead glassy, light from the south-southwest at only 3 mph. That’s prime, clean conditions. The water’s running about 69°F, which feels a touch warmer than normal for this time of year.
By Saturday afternoon, the wind turns onshore and the quality drops off fast, so it’s a morning-only window. Sunday the 26th has a glassy start again, but the swell drops back to a weak 2 ft, and the energy plummets to 59. Not worth the drive.
So, to keep it short: if you want a wave at Nahant Beach, your only real bet is the early session on Saturday, July 25. Everything else is flat or forgettable. Get out there and make it count.

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.
