The Lowdown
Alright folks, Rusty here. Let’s get into what the next couple of weeks are looking like around here.
Well, it’s a pretty quiet start. We’ve got a long stretch of nothing much on offer, so don’t get your hopes up for the first few days. The opening window is a bit of a dud, with only poor surf conditions and tiny waves. It’s not until the 3rd of September that we see a little pulse, but it’s nothing to write home about. Thursday morning brings surfable but very ordinary waves at Nahant Beach with a 4 ft swell out of the SE and a short period of 5 seconds. The wind is light and cross-offshore, so it’s clean, but the energy is weak (128 combined energy) and the swell is junky. That afternoon, the wind swings offshore, but the swell drops to 3 ft. It’s clean, but small.
The real glimmer in this forecast comes on Monday, the 7th of September. That morning, Nahant Beach cleans up with glassy conditions and a 4 ft swell from the ENE with a period of 10 seconds. The combined energy jumps to 255 – that’s moderate energy, and the wave comment says "expect good surf conditions". This is the standout of the whole 16-day window. The wind is dead calm, glassy as it gets, and the swell has some shape to it. It’s a morning mission for sure, because the afternoon gets ruined by a cross-onshore breeze.
The water temperature is about average for this time of year, nothing unusual to report.
After that high point, the rest of the forecast fades back into small, weak, or messy conditions. There are a few more moments of clean surf, like the 8th and 15th of September, but the wave heights are in the 2 ft to 2 ft range with poor energy. It’s not going to get you out of bed.
Honestly, if you’re looking for the best, that Monday morning, the 7th of September, is your only real call. Everything else is a gamble on tiny, weak waves or onshore chop. Crowds are possible at Nahant, so get there early if you can.
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.
