The Lowdown
Alright folks, Rusty here. Let's have a look at what Nahant Beach has in store for us over the next couple of weeks. Gotta be straight with you, it's a pretty grim outlook for the most part. We're looking at a long stretch of poor conditions before we might finally catch a glimpse of something worthwhile.
For the first week, from Sunday the 13th right through to the following Saturday the 26th, it's a write-off. The wave energy is weak to moderate, with the combined swell energy hanging around in the low double and triple digits, like 15 and 16. It's mostly small, disorganized wind swell with short periods around 5 to 8 seconds, and the wind is almost always onshore, cross-onshore, or just plain messy. There's a little window on Wednesday morning the 16th where it's clean with a light cross-offshore wind, but the swell is tiny and weak. Honestly, it's a long gap of poor to very ordinary conditions. The water temp is about average for this time of year.
Things get interesting on Sunday the 20th when the combined swell energy jumps to 258, and it stays in the moderate-to-strong range through the 25th. But the wind is still a problem – mostly cross-onshore from the NE or ENE, making it choppy and lumpy. It's not until Friday the 25th that we see a slight improvement. The swell period stretches to 11 seconds, which is a nice groundswell, and the wind turns light. It's still only marginal, but there's a hint of something better.
Now, the standout is Monday the 28th. That morning, we get a glassy, clean window at Nahant Beach. The swell is a solid 5ft from the ENE with a period of 7 seconds, and the combined swell energy is a strong 227. The wind is light from the north, making it glassy. This is the best on offer, no question. It's a moderate-sized swell, so it might be a bit much for complete beginners, but it's the one session to aim for. Keep in mind that Nahant Beach is a consistent, exposed beach break, and it can get crowded, so expect company.
So, to sum it up: a long dry spell until Monday the 28th. That's your one real shot. Keep an eye on it, because forecasts can change, but as it stands, that Monday morning glass-off is the only game in town.
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.
