Alright folks, Rusty here. Let’s be honest about the next couple of weeks at Nahant Beach. We’re looking at a long, flat spell with almost nothing worth paddling out for. The whole pattern is just quiet. There’s a real gap from now until about Sunday the 19th where the waves are tiny and the energy is pathetic – mostly under 2 ft and combined swell energy barely hitting double digits (33 or less). You’re better off waxing the longboard for a skate session.
Friday afternoon the 10th sees a tiny 2 ft bump from the east at 8 seconds, but it’s glassy. Combined energy is weak (33). The water temp is 66°, right about normal for this time of year, so a spring suit is fine.
Nothing changes through the weekend or early next week. We get a few clean, offshore mornings, but with swell heights of just 0.3 ft to 0.7 ft and combined energy down to 4-9, it’s basically a lake. The wind goes offshore from the west and northwest, which would be sweet if there was any wave to ride.
The only flicker of life shows up on Sunday afternoon the 19th. We get a bump to 3 ft from the east, period a short 5 seconds, with light offshore wind from the WSW. Combined energy is still weak (80). The guidance says it’s “surfable waves but very ordinary conditions.” It’s not a standout by any stretch, just the least bad option after a long dry spell.
Monday the 20th sees a bit more size, 4 ft from the NE, but the wind is a messy cross-onshore at 12 mph, making it choppy. Energy climbs to moderate (109), but it’s not clean.
Tuesday the 21st pumps up to 6 ft on the morning and 7 ft in the afternoon, both from the ENE, with periods of just 6-7 seconds. Combined energy jumps to 305 and then 423 – that’s strong energy. But the wind is a solid 12-16 mph cross-onshore from the NE, tearing it up. That kind of bump, with that wind and short period, looks more fun for a kite surfer than a paddle surfer. It’s going to be a messy, blown-out lump.
Wednesday the 22nd is our best bet. Morning glassy conditions with the swell dropping to 4 ft from the ENE at 7 seconds. Combined energy is still moderate (272). The wind is calm, the surface is glassy. That’s the cleanest window in the whole run. The swell is under 5 ft, so it’s fine for intermediates. After that, it fades back to nothing for the rest of the run.
The second week is a total write-off. Tiny waves, no standout energy. Just flat and clean.
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.
