The Lowdown
Alright folks, Rusty here. Let’s get into it for The Rock-Costa Azul.
We’ve got a solid window of surf coming through, but the first few days are a bit mixed. The standout is going to be the afternoon of Friday the 14th, with a clean 5ft SW swell rolling in. The wind is switching cross-off, cleaning everything right up, and the combined energy hits 1225 (moderate). This is a proper reef break, so you’ll get some long lines from that 17-second period groundswell. It’s an advanced spot, so this is for the experienced crew.
Saturday the 15th is still decent, especially the afternoon with a 4ft SSW swell and cross-off wind, but the energy is a touch down. Sunday morning the 16th is glassy – absolute magic – with a clean 4ft SSW swell, but the energy is dropping to 603. Still very rideable for those who know the rock.
We hit a bit of a lull from Monday the 17th through to Thursday the 21st. The mornings are mostly marginal with light cross-on winds, and the swell drops to around 2ft to 3ft. The aftertimes clean up, but the size is just too small for this exposed reef to really fire. Friday the 21st afternoon looks okay for a sneaky session, with 2ft and clean conditions.
Now, hold on to your leggies. The forecast gets interesting around Monday the 24th. A big pulse of swell hits, but it’s way too big for this break – we’re talking 10ft to 12ft SSE swell. The energy is massive (3039 to 4235), but that’s expert-only territory, and even then, it’s likely too much for The Rock. Tuesday the 25th afternoon settles down to a much more manageable 6ft SSW swell, with cross-off wind and a combined energy of 1606. That’s a solid call for experienced surfers.
Then, Wednesday the 26th is the real sleeper. The morning is glassy, 5ft SSW swell, 11-second period, and the energy is 1147. The afternoon is also glassy, 5ft SW swell, 12-second period, energy 1168. This is the best bet for clean, powerful waves without the crowd. It’s an advanced reef, so you’ll need to know what you’re doing, but the conditions are absolutely prime.
After that, things start to fade again. The end of the month gets messy with strong winds, so don’t waste your time.
Water temp is about average for this time of year, so no need for a thick steamer.
Rusty.

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 The Rock-Costa Azul 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.
