The Lowdown
Alright, let’s get into it. I’ll be honest with you – for us here at Nahant Beach, the next couple of weeks are looking more like a lake than an ocean for most of it. There’s a lot of nothing happening, so we’re really waiting on one specific day that just might save the month.
Right now, through the end of July into early August, it’s a real bummer. We’ve got tiny, short-period slop mostly under 2 ft with onshore winds, and the water is sitting at 62°, which is much colder than normal for this time of year – over three degrees below where we should be. That’s unusual and honestly, it makes a winter wetsuit feel like the only option. The combined swell energy is stuck in the weak range (38 on Friday), so there’s just no power to work with. We’re looking at a long stretch of no real surf until the end of next week.
The only standout in this whole 16-day window hits on Wednesday, July 30th. Thursday morning we see a jump to 6 ft, combined energy climbing to a moderate 380, but by Thursday afternoon it really fires up for an hour or two. That afternoon session brings a 7 ft swell from the NE, pushing the combined energy into a solid 703. It’s short-period windswell at 7 seconds, so it’ll be a bit peaky, but the wind turns cross-offshore from the NW, so wave faces are going to be clean. That’s the call. For Nahant Beach, this is the moment. It’s an exposed beach break, the crowd can be *often* busy, so get down there early.
After that, it drops off a cliff again. Friday (July 31st) through to the end of the run on August 8th it’s back to tiny slop under 4 ft and mostly clean but gutless conditions. The combined energy almost never breaks 50, and often sits below 20. For the second week, it’s really just flat with no energy to speak of.
So, take it or leave it: Wednesday July 30th afternoon is the only real window. Everything else is a wait-and-see, but this kind of blank run isn’t abnormal for the area. Forecasts can change though.

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.
