Alright, Rusty here. Let’s have a look what’s cooking for Atlantida. The first week is pretty quiet, a bit of a slow start with nothing worth paddling out for at first. The first half is small and messy, but there’s something building for the second week.

We start off on Thursday July 9 – pretty flat and average. Cross-on wind and that combined swell energy is only a weak 125. Small 2ft swell from ESE with a 10-second period, but the water is much colder than normal at 56°, over 7° cooler than what you’d expect for this time of year. Not worth getting in for.

Friday July 10 morning shows a little improvement – 3ft from ESE, 12-second period, with clean conditions from a light cross-offshore SW wind. Combined energy is moderate at 269. Just barely worth a look if you’re desperate, but nothing special.

Saturday July 11 stays marginal. Swell hangs around 4-4ft from ESE with a 13-second period, so that groundswell will have some push, but the wind is cross-shore and choppy with rain. Combined energy jumps to 686 mid-afternoon, so there’s moderate wave energy there, but the conditions aren’t cooperating.

Sunday July 12 gets cleaner with cross-offshore winds, but swell drops back to 3-3ft. Clean face but small.

Monday July 13 morning is the first real standout in the first week. 4ft from S at a short 8-second period, but cross-offshore WSW winds at 15 km/h (9 mph) make for clean, peelable waves. Combined energy is moderate at 329. A decent session for the intermediates, but the short period means the waves might be a bit too quick.

Tuesday July 14 and Wednesday July 15 are a write-off – onshore and choppy, poor conditions.

Thursday July 16 – swell drops again, short-period ENE stuff, poor conditions.

Friday July 17 afternoon sees a jump to 6ft from ENE at 8 seconds, with moderate combined energy (672), but cross-shore winds and chop mean it’s marginal. Not great.

Saturday July 18 afternoon – 6ft again from ENE, 8 seconds, combined energy at 636. Still cross-shore chop, not the best.

Sunday July 19 afternoon – 6ft from ENE, still short period (8 seconds), combined energy strong at 709. But cross-shore winds keep it from being clean.

Now, the real standout is Thursday July 24 morning. That’s the one to circle on the calendar. 8ft from ESE, 8-second period – that’s big enough for experienced surfers only (over 8ft is expert territory). But here’s the kicker: glassy conditions with a 5 km/h (3 mph) NNE wind. Combined energy is strong at 685, and the wave comment says “expect very good surf conditions.” That’s a well-constructed, powerful swell for the experts, and the glassy wind will make it clean as a whistle. Just be aware, with a short period, these waves will feel steep and dumpy – not a beginner wave.

The afternoon of July 24 is also notable: still 8ft from ESE, but marginal surf conditions with light cross-onshore wind. Combined energy shoots up to 1801, which is very strong wave energy, but the wind direction and texture won’t be as good as the morning glass-off.

Wednesday July 23 is worth a mention too – 6ft and 6ft from SSE with light winds, but cross-onshore. Combined energy builds to 1085 by the afternoon, so there’s plenty of power, but it won’t be as clean as the 24th morning.

Overall: the first week is quiet and marginal. The second week builds nicely, and Thursday July 24 morning is the best on offer – big, glassy, expert-level waves. Crowds? The break is “often” crowded, so expect company if you’re paddling out.

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.
