The Lowdown
Alright, Rusty here again. Let's talk about what we've got coming up for Nahant Beach. First up, I gotta say, this is a tough stretch. We're looking at a real dry spell for any decent waves. The water's sitting at 62°, which is way colder than it should be for this time of year, a proper shock to the system.
The whole 16-day window is basically a wasteland for surf. We're looking at tiny, weak, short-period slop for days on end. The combined swell energy barely gets into double figures, often hitting just 51 (weak energy) or less. It's just not doing anything.
From Tuesday the 21st through to the end of July, you're chasing scraps. Most days have poor surf conditions with small, weak swells coming from the SE or ESE. The winds are all over the place, often onshore or cross-onshore, which just chops it up. There's a tiny window around the 22nd with a clean, glassy moment from a light W wind, but the swell is a measly 2ft with a period of just 5 seconds. That's not going to push you anywhere.
The end of July and start of August is more of the same. The 31st of July pops up with "surfable but very ordinary" vibes, with a 2ft swell from the ESE and a long period of 10 seconds. With clean conditions and light winds, it's about the best we'll see, but that's not saying much. After that, it's back to tiny, weak, and onshore. Nothing here is going to get you excited.
If you're desperate, maybe look at the morning of the 31st of July for a tiny, clean knee-high wave. But honestly? Don't hold your breath.
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.
