The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at what we’ve got coming up for the next couple of weeks.
Honestly, this is a tough start. We’re looking at a long, dry spell. From now – Thursday, August 6 – right through to basically the middle of the month, there’s just nothing doing. We’re talking about day after day of flat, weak dribble that isn’t worth paddling out for. The wave energy figures are in the single digits or low teens (9, 4, 3... ), and the swell heights are rarely cracking 0.7 ft. It’s a proper flat spell, and you’re not missing a thing. Use this time to fix your dings or clean the wax off your deck.
The first real hint of life doesn’t show up until Thursday, August 13. Even then, it’s a stutter. The afternoon brings a sliver of swell from the SE, only 2 ft, with a short 4-second period. The energy is weak (22), but the wind turns offshore from the WNW. The water’s about average for this time of year. Nahant Beach is the only game in town, and it’s a consistent beginner spot, but this is tiny stuff for a beach break. It’s clean, which is nice, but you’ll be fighting for scraps.
Friday, August 14, holds a little more promise. Morning surf at Nahant Beach sees a similar SE swell, 2 ft, with that same short period (5 seconds) and clean offshore wind from the W. The energy is still weak (28). Afternoon sees the size drop to 1 ft. It’s clean, but it’s a beginner-level micro-swell. If you’re desperate for a paddle, this is it, but don’t expect any real waves.
From there, it fades back into a flat, unremarkable run of days through the end of the window. We see tiny bumps on August 19 that get the energy up to 27, but the wind gets messy, cross-onshore from the NE and ESE. That’s a no-go. The very last entry on August 21 shows a 3 ft NE swell with a 5-second period and onshore wind – poor conditions. Nothing to get excited about.
So, the bottom line: this stretch is a write-off for decent waves. There are no standouts. It’s a consistent spot that’s going to stay flat or tiny and clean for a few days mid-month. That’s the best we can say. It tends not to stay this poor forever, but for now, the forecasts are what they are. Keep the board in the bag.

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.
