Alright, grab a coffee, listen up. It's Rusty.
First off, I gotta be straight with you – it’s looking flat and lifeless out there for a solid stretch. Nahant Beach is the only spot on the cards for the whole 16-day run, and honestly, the surf is struggling. The water’s sitting at about 68°, which is a touch warmer than normal for this time of year, but that’s about the only good news. The combined swell energy is barely registering – we’re seeing values around 11 to 16 for the first few days, which is weak. For the first week, from Sunday the 12th right through to Friday the 17th, it’s pretty much all tiny 0.3ft to 0.7ft dribble. Monday afternoon on the 13th sees a bump to 3ft, but that’s coming from the SSE with a shocking 4-second period – that’s just wind slop, not real surf. Clean conditions pop up here and there, like Tuesday morning on the 14th with a moderate offshore from the WSW, and there’s some glassy stuff late Saturday the 18th, but the waves just aren’t there to make it worthwhile.
There is a bit of a pulse late in the second week. Monday afternoon on the 20th kicks up to 4ft from the SSE, combined energy hitting 58, but that’s still pretty weak for a bigger wave, and the period is a measly 5 seconds – it’s going to be choppy and messy with a cross-onshore wind. Tuesday the 21st stays similar with 3-3ft but the period stays short. Honestly, for a beach break like Nahant Beach, this kind of short-period, onshore wind setup just stirs up chop; it’s more interesting for kite surfing than paddling. The rest of the month into the 27th fades back to tiny 0.7-1ft with clean but small conditions. Nothing here is a standout. The best you could hope for is maybe a clean, small session on Saturday the 18th afternoon when it’s glassy – but with 0.7ft and a 7-second period, you’re basically floating.
So, to wrap up: there’s no real surf to get excited about. Nahant Beach is consistent but rarely gives you anything worth paddling out for in this window. Keep an eye on the charts, but for now, the wax stays in the bag.

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.
