The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Nahant Beach over the next couple of weeks.
Straight up, I gotta be honest with you – it’s a flat spell and a half. There’s just nothing to get excited about across the entire 16-day window. The finder is coming up empty, and looking at the guidance, it’s a consistent beginner spot, but right now it’s just not delivering. From now through to the 13th of August, we’re looking at a long, dry gap with no surfable waves. The only energy we see is a couple of pulses around the 30th and 31st of July, where the swell bumps up to 5ft and 7ft, but the wind is a mess – cross-onshore and choppy, with the combined energy hitting 286 and 452 respectively, which is moderate to strong. Still, it’s all tagged as poor surf, so don’t bother paddling out.
The water temperature is about average for this time of year, nothing weird going on there. The break itself is exposed, but the swell direction (ENE) is what the spot likes, and there’s a consistent offshore wind direction (W) in the guidance, but we just aren’t seeing that alignment in the forecast. Crowds are likely here when it’s good, but that’s not the problem right now.
The only slight glimmer comes on the 7th and 8th of August, with glassy conditions in the mornings, but the swell is a pathetic 1.0ft and 0.7ft – not enough to push a paddleboard. The 9th of August has another glassy morning, same story. The 10th and 12th of August offer clean, cross-off winds, but again, the swell is tiny, under 2ft, with weak energy readings (14 to 34). It’s just not happening.
This is one of those blank runs that’s pretty normal for the area when the stars don’t align. Keep your hopes up, though – it never stays this poor for long, and forecasts can change. For now, the board stays in the car.
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.
