The Lowdown
Alright folks, Rusty here. Let’s have a look at the 16-day picture for the region.
Alright, so we’ve got a bit of a slow start, but there’s a few windows that could be worth paddling out for. The first session that’s worthwhile is on Tuesday morning, August 4th. The swell is a modest 3ft from the SSE with a long 12-second period, giving it some decent push. The moderating wave energy is moderate (297) and the real kicker is the wind: it’s glass. That’s a major positive, so expect clean, silky conditions. The water temp is about average for this time of year, so no surprises there.
Atlantida (beach/pier) is the spot. It’s an inconsistent break, so don’t expect perfection, but when it’s this clean, it’s a beautiful thing. This is the best morning on offer in the first week. The crowd factor is ‘often’, so you won’t be alone, but with the glassy conditions, the wait for a set will be worth it.
The next notable window is Wednesday morning, August 5th. Another 3ft from the SSE, period dropping to 10 seconds, still a nice little wave. The energy is moderate (176) and it’s glassy again. The weather is light rain, but the wind is off the WNW at 5 km/h, keeping it clean. It’s a solid, if unspectacular, Wednesday morning sesh.
Things start to get more interesting on Saturday afternoon, August 8th. The swell jumps a bit to 4ft from the SSE, but the period is a very long 16 seconds. That’s proper groundswell. The combined energy is strong (1515). This is a standout session for the period. The wind is a light 10 km/h cross-shore, so it’s manageable. Because it’s a long-period swell, it might break a bit too straight at the beach, but it’s still the best-looking afternoon of the entire forecast. Expect some powerful, clean lines.
The following week, there’s a really promising morning on Wednesday, August 12th. The swell is 5ft from the S, period of 11 seconds, moderate energy (591), but the wind is offshore from the W at 5 km/h. That’s pure magic. It’s clean, it’s good, and the “expect very good surf conditions” note backs it up. This is the other standout.
Beyond that, there’s a lot of wind and chop. The swell gets big, but it’s messy. The afternoon of Sunday, August 16th sees a 10ft swell from the E, but at 8 seconds, it’s short-period and strong cross-onshore winds will make it a chore. That’s one for the experts only, if anyone. The wind and tide are favorable, but the swell is simply too big and messy for this beach.
So, the two best windows are Tuesday morning, August 4th for the glassy waist-high fun, and Wednesday morning, August 12th for the offshore, chest-high groundswell. Get on it.
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.
