The Lowdown
Alright folks, Rusty here. Let’s get into it for Atlantida. The next 16 days are a real mixed bag for this beach/pier setup. We’ve got some serious waiting to do, and the first few days are a write-off with onshore wind and chop. The real window of opportunity is a narrow one, so keep your eyes peeled.
The first couple of days are a total loss. Sunday the 30th of August and Monday the 31st are all about cross-onshore winds and rain, with messy, poor surf. The swell is there, but it’s junk. Not worth paddling out for.
Things start to look up by Tuesday the 1st of September. The early morning is the standout of the whole outlook. We’ve got a 7ft swell from the east (E) with a 9-second period, and the wind is light and cross-offshore. The water is sitting at a pretty normal 61°, which is about average for the time of year. The combined swell energy is a solid 702, which is moderate, and it’s gonna be clean. That’s your best chance for a session. The afternoon, however, gets ruined by a fresh 19 mph cross-offshore wind, so get on it early.
Wednesday the 2nd of September is still surfable, but a step down. The morning has a 5ft swell from the ESE, and the wind is still cross-off, so it’s clean. The afternoon turns a bit messy with a cross-shore wind. Not the best, but you could find a few.
The rest of the first week and into the second week is a real struggle. From Thursday the 3rd through to the 12th, the conditions are mostly marginal or poor. The swell drops off, and the wind keeps shifting around. There’s a brief flicker on Saturday the 5th of September with a decent 5ft swell from the south in the morning, but the wind is cross-off, so it’s clean. The combined energy is 367, which is moderate. It’s a short window though.
Sunday the 6th of September has a nice 6ft SSE swell with a 10-second period and a combined energy of 725, which is moderate. The morning is clean with cross-off winds, but it’s only a marginal call. The afternoon gets a cross-shore wind.
The real long-range hope is on Sunday the 13th of September. The morning looks good with a 5ft swell from the east (E), a 7-second period, and light cross-off winds. The combined energy is 284. It’s clean and should have some fun waves, but it’s over a week away, so don’t book the day off just yet.
Monday the 14th of September has a 6ft ENE swell, but the wind is cross-on and light. It’s a marginal call.
Overall, the best bet is the Tuesday morning, 1st of September. Get on it, because the window is small. The rest is a lot of waiting and hoping for a clean one.
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.
