Table - best surf conditions forecast for Nahant Beach over the next 16 days.
Alright folks, Rusty here with the Nahant Beach look ahead. Gotta be straight with you – it's looking pretty bleak for a while. We're staring down the barrel of a long week or more with barely a bump. The first real, rideable wave is a long way off, so patience is the name of the game.
From now and through the next week, the energy is flat-out weak. We're talking tiny little slop, swell heights barely cracking 3 feet, mostly out of the east, and to be honest, a lot of it is messy. The wind is all over the shop too, mostly cross-onshore, and the water's sitting at about 68°, which is a touch warmer than usual. It's a frustrating mix of no swell and choppy conditions.
There's one little bright spot on Thursday the 9th in the morning. The wind goes cross-off from the WSW at about 6 mph, cleaning things up nicely, but the swell is tiny, just 3 feet from the east, with a period of 8 seconds. The combined energy is weak (90). You could get a wave, but it's very ordinary. Best of a bad bunch.
After that, the well runs dry. We've got glassy mornings on Friday the 10th and Wednesday the 15th, but with swell heights down to about 0.3 feet, you're just bobbing around. That 16-second period on the 15th is a long-period groundswell, but at that height, it's a total non-event. The energy reading is a measly 11.
Now, the real standout is way off on the horizon, but I gotta flag it. We're looking at Monday the 20th. It's a long way out, so don't get your hopes too high, but the morning is showing us something. Glassy conditions, clean as a whistle, with a 2-foot swell coming from the SE with an 8-second period. The energy is finally building, hitting 67 – that's moderate. The wind is dead calm, which is a massive bonus. For a beginner-friendly break like this, in this outlook, that's about as good as it gets. It won't be big, but it'll be clean and rideable.
The afternoon gets a bit bigger but the cross-onshore wind comes back. So, pencil in the morning of the 20th. It's the one window in this whole forecast that really lines up. For everything else, you're better off taking the dog for a walk.
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.
