The Lowdown
Alright, grab a coffee, let's see what's cookin'.
Alright, the truth is, things are looking pretty flat around here for the next week and a half. Nahant Beach is usually a reliable spot, but we're in a bit of a dry spell. The swell energy is weak, barely getting into triple digits at its best – we max out at a modest 240 in the combined energy bank, which is just not gonna get you stoked. The water temp is sitting at 65°, which is a good degree or so colder than average for this time of year; you might want a spring suit.
The only time we see any real size is right at the start, on Wednesday the 29th of July. We get an ESE windswell pushing 5ft, but it's coming in at a short, weak 6 seconds. That's just bumpy and messy, especially with a 16 mph onshore wind. It's going to be choppy and poor. Thursday holds similar conditions with a 6ft ENE swell, but the wind is cross-onshore and there's a cross-chop making it ugly.
After that, it's a slow slide into tiny surf. The energy drops off a cliff, with combined energy values sitting below 100 for days. From Friday the 31st right through to the second week of August, we're looking at knee-high dribble at best – 1ft or 1ft if we're lucky. A couple of mornings, like Saturday the 1st of August, look glassy, but there's nothing to surf. The wind does turn clean and offshore on a few occasions – Monday the 3rd and Tuesday the 4th see some light offshore breezes – but the swell is basically non-existent.
There is a little blip on the horizon. On Wednesday the 12th of August, we see the swell tick up to 4ft from the NE with a short period. The wind will be cross-onshore again though, so don't expect magic. It's just not the kind of energy that makes this exposed beach break sing.
Honestly, for a beach break, the set-ups we get here with small swell and onshore winds are pretty average. You might be better off looking for a stiff breeze and a kite if you're desperate, because the paddle surfing looks grim for this stretch.

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.
