The Lowdown
G’day, Rusty here. Let’s be straight with you about Nahant Beach – it’s looking like a long, quiet stretch with very little worth paddling out for. The first good surf doesn’t really show up until Wednesday morning, 22 July, so you’ll be staring at flat, weak conditions for the first five days. From Friday 17 July right through to Tuesday 21 July, it’s all poor surf with tiny ankle-biters and no energy. Not a wave worth mentioning.
On Wednesday 22 July, things finally tick over. The morning brings a 4ft SE swell with a short period of 6 seconds, and the combined energy is moderate at 107. The wind is a light cross-offshore breeze, so the surface stays clean. It’s surfable but very ordinary – not a standout, just a chance to get wet. The afternoon cleans up even more with a moderate offshore wind from the WNW and 3ft SE swell, period 9 seconds, energy creeping up to 121. Still nothing to drive for, but you can get a few.
Thursday 23 July is the best of a pretty average bunch. The morning has 2ft SE swell with a 10-second period, offshore wind from the WSW, and clean conditions. The energy is moderate at 77. The afternoon picks up: 3ft SE swell, 8-second period, and a light cross-offshore breeze. Energy bumps to 162, which is moderate. It’s clean, but the swell is small and short-period. For a beginner-friendly spot that’s consistent and exposed, you’ll find some fun little waves, but don’t expect anything memorable.
Friday 24 July through to Saturday 1 August is a long, sad run of tiny surf, poor conditions, and onshore chop. The only glimmer is Saturday 25 July afternoon: glassy conditions with a 5ft SSE swell, period 5 seconds (very short), energy 161. That’s a small, weak, sloppy windswell, and the glassy surface is the only thing saving it. Not a standout.
Overall, there’s no true standout here. The best window is Wednesday 22 July through Thursday 23 July, when the swell barely reaches 4ft, combined energy stays moderate at best, and the winds are clean. The water temp is 69°F, a touch warmer than usual for the time of year (anomaly 2°F), so at least it’s not cold. But for a surfer? You’re looking at a lot of flat days and very ordinary waves. Keep the board waxed and wait for a better forecast.
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.

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.
