The Lowdown

Alright folks, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty flat and frustrating. We got a long stretch of nothing before things might finally start to wake up. Hang tight, because it’s a waiting game.

The outlook starts off with a real dud. From Wednesday the 5th all the way through the 17th, we’re looking at poor surf conditions. It’s not even a question of quality—there just isn’t any swell. We’re talking ankle-biters and dribbles, with the energy barely registering. There’s a brief moment on Wednesday the 12th where a long-period swell (14 seconds) shows up, but it’s only 0.3ft, so you’d need a microscope to see it. The winds are often light and clean, but with nothing to push, it’s just a flat, glassy lake out there. It’s a real tease.

Now, for the first real sign of life, we have to wait until Monday the 18th. It’s still not good, but it’s something. We’ll see some chest-high slop, around 3ft from the ESE, but the period is short (8 seconds) and the wind is all over the place—cross-shore in the morning and then a cross-onshore breeze kicks in the afternoon, making it choppy. This isn’t a surf day, it’s more of a “sit on the beach and watch the chaos” day.

Tuesday the 19th is a slight step up. The swell stays around 3ft from the ESE, but the magic happens with the wind. A cross-offshore SW breeze in the morning builds through the afternoon, and it cleans the whole thing up. The energy finally gets into the triple digits, so there’s finally some push. This is shaping up to be the standout of the whole run. Because it’s a beach break and not huge, it could be alright for the more adventurous beginners. Just be aware, it’s a short-period wind swell, so it might not have the punch of a groundswell, but it’s the only real option we got.

Finally, Thursday the 20th is the last day in the window. The swell backs off to around 2ft, but the wind stays light and cross-offshore from the WSW. It’s surfable but very ordinary. If you’re desperate for a wave, you could probably find something, but don’t expect any fireworks.

So there you have it. One day—Tuesday the 19th—looks like the pick of the bunch. Everything else in this 16-day window is a write-off. For a spot like Nahant Beach, this kind of flat spell is normal, but it never lasts forever. The forecasts can change quick, so keep an eye on it.

Rusty out.

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.
