The Lowdown
G’day, it’s Rusty.
Alright, lookin’ at the next 16 days for Atlantida. It’s a real mixed bag – some average stuff, a couple of gems if you time it right. Let’s get into it.
Thursday the 27th kicks off with a 4ft SSE swell, period about 13 seconds, and moderate energy (734). The wind’s cross and cross-on, so it’s a bit choppy. Nothin’ special.
Friday the 28th sees the swell swing to the east-northeast, 6ft in the morning with a shorter 9-second period. Energy’s moderate (479), but the wind’s cross – small ripples on the face. Still pretty ordinary.
Now, Saturday the 29th morning is a bright spot: glassy calm, 4ft ENE swell, 9-second period, and moderate energy (280). It’s small but clean. The afternoon stays tidy with a light cross-off breeze and 4ft waves.
Sunday the 30th is a washout with heavy rain and onshore winds. Then Monday the 31st – hold onto your board. Morning brings a huge 10ft ENE swell, 9-second period, and massive energy (2029). Wind is light and onshore, and it’s way too big for this spot – experts only. But the afternoon is the standout: the wind goes glassy, the swell drops to 8ft from the east, and the energy is still strong (805). Clean, solid, and the best session of the whole run. Crowds are possible, so get out there early.
Tuesday the 1st of September and Wednesday the 2nd have clean cross-off winds, but the swell drops to 5ft to 6ft with short periods (8 to 9 seconds). Decent but nothin’ to write home about.
From Thursday the 3rd, it fades. Thursday morning has 4ft from the south with a 10-second period (349 energy) and cross wind – weak. Friday the 4th is tiny, just 2ft and glassy – barely worth it. Saturday the 5th and Sunday the 6th are poor with onshore winds and lumpy conditions.
Then there’s a little pulse Monday the 8th of September – a 8ft ENE swell, 9-second period, and strong energy (1007). The wind is light cross, so there’ll be some fun ones that morning. It’s the only other session that scores decent.
After that, the last few days are small and messy. Friday the 11th has a 5ft SSE swell with a 12-second period and strong energy (1015), but the wind’s cross-shore with chop.
Bottom line: The absolute standout is Monday the 31st of August afternoon – glassy, solid 8ft ENE swell, and clean. If you want something smaller and cleaner, Saturday the 29th morning is your spot. The rest is pretty average. Keep your eyes peeled, but don’t expect much after that first week.

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.
