The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for your local stretch.
First up, the water temperature at Atlantida is sitting at 62°F, which is pretty much bang on average for this time of year, so no surprises there.
The next few days are a real mixed bag, and honestly, not much to get excited about. Saturday the 25th has a small 4ft swell from the ESE with a short 8-second period. The morning is glassy, and the combined swell energy is weak (309), so it’s surfable but nothing to write home about. That afternoon the wind turns cross-on and the swell drops off.
Sunday and Monday offer similar knee-to-waist high dribble with light winds but short period, and the energy stays low. It’s all pretty average.
We hit a bit of a dry spell from Tuesday the 28th through to Friday the 31st of July. The swell is small, winds are messy, and most of the time it’s poor. There’s a brief window on Wednesday morning the 29th with a light offshore wind and a clean 2ft wave from the south, but it’s tiny and barely breaking.
Now, the first real standout comes on Saturday the 1st of August. The morning shows a clean 5ft swell from the ENE with a short 8-second period, but the wind is offshore from the NW, and combined swell energy is moderate (350). The setup looks clean and fun for intermediate surfers. The afternoon goes glassy with 4ft waves.
But the absolute best on offer is Tuesday the 4th of August. The afternoon sees a solid 7ft ENE swell with an 8-second period, strong combined energy (981), and a clean cross-offshore wind from the SW. That wave will have some push and shape. This is going to be the pick of the entire forecast. It’s a bit big for beginners, so it’s better suited to experienced surfers.
After that, the swell backs off and the wind turns messy again through to the 9th of August. There’s a moment on Thursday the 6th of August afternoon with glassy 3ft waves, but it’s weak and only worth a look if you’re desperate.
So, to sum it up: Saturday the 1st of August morning is the first real chance for a fun session, and Tuesday the 4th of August afternoon is the heavyweight. Don’t hold your breath for anything before that.
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.
