The Lowdown
Alright, Rusty here. Let's have a look at what the next couple of weeks are serving up for us.
Honestly, it’s a pretty grim stretch ahead for the most part. We’ve got a real dry spell on the cards, with nothing really worth paddling out for until we hit the 4th of August. That’s a solid week of flat, messy, or just plain ugly conditions to sit through. The first real glimmer of hope comes on Tuesday the 4th, and it’s a beauty.
The standout window is definitely Tuesday the 4th of August. We’ve got a clean, glassy morning with the wind swinging offshore from the SW, just 6 mph. That’s a major positive. The swell is a solid 4ft from the SSE, with a long 11-second period, so that’s proper groundswell, meaning some real push and shape. The combined energy is strong at 385 (moderate wave energy). This is the one to circle on the calendar. For a spot like Atlantida, which is a beach/pier setup and inconsistent, this is a rare treat. The afternoon goes even more glassy, with the wind dropping to nothing. Crowds are often here, so expect some company. This is the pick of the entire forecast.
After that, things get a bit messy again. The 5th and 6th are a write-off with onshore winds and chop. The 7th is marginal. There’s another flicker of hope on Saturday the 8th of August, with a glassy morning on a 4ft, 8-second S swell. The combined energy is moderate at 216, and with glassy conditions, it’ll be clean, but it’s a short-period swell, so it won’t have the same grunt as the 4th. The 9th has some clean-ish cross-off wind but the swell is a bit mixed up. The 10th is a no-go, but the 11th of August rolls in with another good morning. We’ve got a 3ft SSE swell (11 seconds) with a clean cross-off wind from the SW at 9 mph. The combined energy is a solid 463 (moderate wave energy). It’s not the standout of the 4th, but it’s a solid, clean option for the second week.
So, to sum it up: if you’re desperate, the 4th of August is the absolute best on offer – clean, long-period groundswell, and just the right size. The 8th and 11th of August are your fallback days, but don’t expect magic. The rest of the time, you’re better off waxing your board at home.
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.
