Alright, Rusty here again. Let's put it in feet and knots for the old-school crew. The outlook is grim, I won't sugarcoat it.
The next week is flat. From Monday the 13th through the weekend of the 19th, we’re talking swell heights barely reaching 2 feet, and most of the time it’s a pathetic 0.3 feet. The wave energy is laughable, always in the single or low double digits (10, 28, 42). The wind varies, sometimes offshore, but there’s simply no swell to push. The water is about 69°, which is a touch warmer than average for July, but that’s the only highlight. Forget the board for the first six days.
We get a tiny pulse on Tuesday the 21st. The morning shows a 2 feet swell from the southeast with a 10-second period. The energy climbs to 57 (moderate), and the wind is light and clean out of the SSW. The report calls it “surfable waves but very ordinary,” and I’d give it a 1 out of 10. It’s the best we’ll see, but it’s still pretty weak. For Nahant Beach, a beginner spot, this little clean wave might be enough for a longboard, but it’s nothing to get excited about.
After that, it’s a complete shut-down. From Wednesday the 22nd all the way to the 28th, it’s tiny, weak, short-period slop (0.6 feet to 2 feet, periods under 8 seconds). The energy is pitiful, barely cracking double digits. The wind is okay sometimes, but there’s no swell. The Sunday morning of the 26th has a gentle offshore wind from the WSW with a 1 foot swell, but it’s a drop in the bucket.
So, bottom line: for the next 16 days, you’re not surfing. This is a real dry spell, but it’s one of those things where if you wait, it’ll change. Keep your eyes on the ocean, and hopefully the next window will bring something real.
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.
