The Lowdown
Righto, Rusty here, looking at the charts for the next couple of weeks. To be honest, it's a pretty bleak run for Nahant Beach. The short-range models are showing nothing, and this quiet spell stretches for a solid run of days.
We’ve got a bit of a wait on our hands. The first hint of anything worth paddling out for doesn't show up until Thursday the 30th. The early part of the period is a total write-off – small, chopped-up, and just plain ordinary.
Now, Thursday the 30th, that's where things get a little more interesting. We see an ENE swell pushing in at 6 ft, with a moderate wave energy reading (250). The wind swings to a clean cross-offshore from the NW in the morning, cleaning things up nicely. By the Thursday afternoon session, the wind gets even lighter, coming from the WNW at 6 mph, and the surf stays clean. It’s still a short-period swell, but it’s the best we’ve seen and the only real standout in this forecast. The water temp is sitting at 62°, which is a whopping 5° colder than average for this time of year – you’ll definitely feel that bite.
Friday the 31st keeps the clean conditions going with offshore west winds, but the swell starts to fade. The morning is your best bet with 4 ft and gentle offshore wind (9 mph) and a combined energy of 157. It’s surfable, but nothing to write home about.
After that, it’s back to the small stuff. The waves drop right off, and we’re looking at ankle-snappers for the rest of the run into the second week of August. A few glassy mornings pop up on the 1st and 9th, but the swell is just too weak to push anything worth getting out of bed for. This is just one of those quiet spells where the ocean needs a good kick up the backside.
Keep an eye on the charts, but for now, you might want to get the fishing rod out.
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.
