The Lowdown
Alright, folks, Rusty here. Let’s get into it. We’ve got a 16-day window, and there’s a bit of a slow start, but the first real surf shows up on Wednesday, September 2nd.
The overall pattern sees a bump of swell mid-week, then a bit of a lull, before things start to look more promising again towards the end of the first week and into the second. The standout for the whole period, the one you’d want to circle, is the morning of Wednesday, September 2nd, followed by a promising run later on.
Atlantida is our only real option here. And it’s an inconsistent spot, so you have to be a bit patient. The first real action is Wednesday morning, September 2nd. We’re looking at a clean 6ft swell from the ESE, with a period of 10 seconds. The wind is light and cross-offshore from the W, which is going to groom those waves nicely. The water is sitting at 61°, which is a touch cooler than usual for this time of year, but nothing too crazy. The combined energy is moderate at 547. This is the best on offer, no doubt.
The afternoon on the 2nd drops off a bit with a funky cross-on wind, but Thursday morning, the 3rd, is a solid follow-up. The swell drops to 4ft from the ESE, same 11-second period, and the wind is again light cross-off from the W. It’s clean, but a bit smaller. The energy is moderate at 448.
Friday the 4th is a step down to small, weak surf. Saturday the 5th and Sunday the 6th are pretty ordinary, with onshore winds and small, choppy swells. There’s a gap of a few days of poor quality here.
Now, Monday morning, September 7th, things start to look up. The swell comes back up to 6ft from the SSE, period of 9 seconds, with a light cross-off wind from the SW. The energy is moderate at 446. It’s worth a look.
After a few more days of messy, wind-affected surf, we get to the next real standout. Thursday morning, September 10th, brings a clean 6ft swell from the ENE, period of 9 seconds, with a nice light cross-off wind from the SW. The energy is moderate at 568. This is a solid, muscular wave.
The following week is a bit mixed. Saturday the 12th has a clean 4ft swell from the E, but it’s smaller. The real gem in the second week is Monday morning, September 14th. This one is special. We’ve got a 5ft swell from the ENE, period of 7 seconds, and the wind is glassy. That’s right, dead flat, no wind. The energy is moderate at 555. For a beach/pier setup, that glassy condition is a massive, massive positive. It’ll be clean and smooth.
After that, Tuesday the 15th and Wednesday the 16th get messy with onshore winds again. But the window closes out strong on Thursday morning, September 17th. A clean 5ft swell from the E, period of 10 seconds, with a slight cross-off wind from the SW. The energy is moderate at 554. A nice way to finish.
So, to sum it up: the best surf is the morning of Wednesday, September 2nd, and then the glassy morning of Monday, September 14th. The 14th is the one to gamble on for perfection. The rest is a mixed bag of workable windows and days to stay on land.
Rusty.

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