The Lowdown

Alright, grab a coffee and listen up. Rusty here.

To be straight with you, the next week and a half is going to be a quiet one. We're looking at a long stretch of tiny, weak surf with barely enough energy to get excited about. The good news is there’s a pulse of swell showing up for the final weekend of the period, so let’s get into it.

Starting from now, the first few days are a total write-off. We’re looking at flat, gutless conditions with swell heights barely hitting 0.3 ft and combined energy in the single digits (3). The water is sitting at 67°, which is a bit colder than we’d expect for this time of year. There’s nothing to recommend here for a paddle.

Moving through the first week, the story doesn’t change much. We get a few days with a light offshore breeze, which is nice, but the swell is still a joke – 0.3 ft to 0.7 ft with energy staying below 20. Monday the 12th sees a blip of 3 ft from the NNE, but it’s a short period windswell (4 seconds) and the wind is cross-onshore. It’s messy and not worth the drive.

Thursday the 15th through the 21st is more of the same: small, inconsistent, and forgettable. We get a few clean windows with offshore winds, but the swell is simply not there. It’s a frustrating stretch of flatness.

Now, let’s talk about the standouts. The only real window of opportunity arrives on Saturday the 22nd and Sunday the 23rd. The best bet is Nahant Beach. On Saturday morning, we see a 3 ft swell from the E with a period of 8 seconds, and combined energy ramps up to 140. The wind is a clean cross-offshore from the NNW, which is a major plus. It’s not a monster, but it’s the biggest and cleanest we’ve seen all forecast. The wave quality is still rated as "very ordinary," so don’t expect perfection, but it’s the only real chance to get wet. On Sunday the 23rd, the swell drops a touch to 3 ft from the E, with energy at 99, but the wind stays clean from the NW. It’s a bit smaller, but still a solid option for a Sunday session.

Given the long run of flatness, the fact that Nahant Beach is consistent and exposed to the right swell direction is a glimmer of hope. The crowds are likely to be there, but with so few options, it’s going to be the place to be.

So, to sum it up: the first 13 days of this outlook are a total bust. The only real chance for a surf is on the 22nd and 23rd at Nahant Beach. It’s not going to be epic, but it’s 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. 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.
