The Lowdown
Alright, this is Rusty. Let’s take a look at what Atlantida has cookin’ for the next couple weeks.
First thing you need to know, the water temp is just about average for this time of year, so no surprises there.
The big standout is Monday, August 24th, first light. We’re talking about a solid 7ft swell out of the SSE with a long 14-second period. That’s real groundswell, packing a heavy punch with strong wave energy (1965). The wind is a light, cross-offshore breeze, so those waves are gonna be clean and lined up. The report says excellent surf for experienced surfers, and at 7ft, this is definitely not for beginners. This is the session you set your alarm for.
Tuesday the 25th, the swell backs down a bit to 5ft, still from the SSE, but the wind goes cross-shore and it gets that marginal tag. It’s rideable, but not special. The afternoon gets chopped up.
Wednesday the 26th of August shows a nice 7ft swell with a long 14 to 15-second period again, giving us strong wave energy (1691 and 1984). But the wind is the spoiler – cross-shore in the morning and a strong cross-onshore in the afternoon that’ll trash it. A real tease.
We hit a flat spell from Thursday the 27th of August through the end of the month. There are some small waves around 4ft to 5ft, but a couple of mornings and afternoons are glassy. Saturday the 29th afternoon is glassy with a 4ft ENE swell, and Sunday the 30th afternoon is glassy with a 5ft ENE swell. Those are your longboard or funboard windows when you just want clean, easy waves with no wind. Not powerful, but real fun.
Into the first week of September, it gets smaller and weaker. Tuesday, September 1st morning has a clean 4ft swell, but it’s short period (7 seconds), so it’s weak. Wednesday, September 2nd morning is glassy again with a 5ft S swell (9 seconds), giving you another solid longboard session.
After that, it really drops off – 3ft, 3ft, 2ft through the 6th of September. The combined wave energy gets weak (91 to 266). Not much to write home about.
Then, looking way out to Monday, September 7th and Tuesday, September 8th, there’s a pulse of swell building back. Monday morning shows a 6ft ENE swell, but with a short, choppy 7-second period and cross-shore winds. Tuesday the 8th morning shows 7ft from the ENE with 8 seconds and light cross-shore wind. It’s a long-range call, so don’t bet the farm, but it could be a nice return to form if the wind behaves.
Best bet: Monday morning, August 24th. Second best: those glassy afternoons on the 29th and 30th of August.
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.
