The Lowdown
Alright, Rusty here, let’s break down what’s cooking at Atlantic Terrace.
Honestly, the next two weeks are a real bummer. We’ve got a long, flat, and windy stretch ahead with almost nothing worth paddling for. The first real glimmer shows up late in the game, but it’s not setting the world on fire.
From the 15th all the way through the 28th of September, it’s a massive dry spell. Waves are tiny, mostly under 2ft, with short periods and messy winds. Day after day, we’ve got light to moderate cross-shore breezes stirring up chop and lousy shape. Even when a pulse of swell hits around the 20th and 21st, with waves pushing 4ft to 6ft, the wind is either strong cross-shore or onshore. The combined wave energy hits 200 to 291 (moderate energy), but the quality is poor. It’s blown out, lumpy, and not worth suiting up for. That 6ft swell on the afternoon of the 20th might look tempting, but with strong cross-offshore winds and a short 6 second period, it’s a foamy mess – more of a kite-surfing day than a paddle-surfing one.
Then, after a long, quiet stretch, we finally get a tiny window. On Monday the 28th of September, in the afternoon, the wind goes glassy – dead calm – and we get a small 2ft swell from the ESE with a 9 second period. The combined energy is only 59 (weak), and the report calls it “surfable waves but very ordinary conditions.” It’s the only moment in the whole forecast that even gets a 1 out of 10. For a spot that’s a beach and reef setup, exposed to the SE, that glassy wind is a total game-changer, cleaning the surface up beautifully. But the swell is tiny and inconsistent. It’s a longboard or a soft-top kind of session, maybe a sunset cruise, but don’t expect much power.
After that, it’s right back to tiny, blowy junk for the rest of the period.
So the standout? There isn’t one. The only highlight is that glassy Monday afternoon on the 28th. It’s not the kind of swell that gets you out of bed early, but if you’re itching for a clean, small-wave paddle, that’s your one shot. The water temp is about normal for this time of year.
Hang in there, mate. This run is a shocker, but it won’t stay flat forever.

Information about the Atlantic Terrace Surf forecast
The above surf forecast table for Atlantic Terrace provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Atlantic Terrace can be found by selecting the local surf guide option on the grey menu. Our Atlantic Terrace 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 (Atlantic Terrace) 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 Atlantic Terrace 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.
