The Lowdown
Alright folks, Rusty here with a look at what’s on the cards for The Rock-Costa Azul. We’ve got a run of small, clean windows building to a serious pulse later on, so let’s break it down.
Right off the bat, the water temp is sitting right where you’d expect for this time of year. There’s no big anomaly to talk about, so you can leave the winter steamer at home for now.
For the first week, don’t expect much power. We’re looking at knee-to-waist high sets, around 2ft to 3ft. The energy is modest, with readings in the 400 to 900 range (moderate wave energy). The real story is the quality. We’ve got a few sessions with glassy conditions or light offshore wind coming out of the SSW and SW. Tuesday afternoon the 11th, with a light offshore breeze and clean lines, is a solid shout. Wednesday the 12th is a beauty – both morning and afternoon are dead glassy. The swell is small, but you’ll be trading waves with just a handful of regulars.
Thursday afternoon the 13th looks like the standout of that first week. The swell direction swings SW, still small at 3ft, but the cross-off wind makes it clean and the energy kicks up to 665. It’s not gonna be barreling, but for a long board or a retro single-fin, that’s going to be your pick.
We hit a bit of a lull with onshore winds from the 16th to the 18th, making things a little bumpy. But the long-term forecast is where things get exciting. Friday the 22nd – hold onto your board. The swell jumps to 8ft from the SE, with a clean cross-off wind. The energy hits a whopping 3013, which is strong. That is a session for experienced surfers only; the reef will be stacking up some heavy, pitching walls.
The following day, Sunday the 23rd, the swell is properly pumping. We’re seeing 13ft SSW groundswell, but the forecast is straight up saying it might be too big for this break to handle properly. That kind of juice with a 13-second period will be closing out hard or washing straight through the lineup. If you’re a seasoned charger wanting a wild look, maybe. But for the average surfer, Saturday the 22nd afternoon is the one to circle on the calendar.
Stay safe out there.
Rusty.

The above surf forecast table for The Rock-Costa Azul provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Rock-Costa Azul can be found by selecting the local surf guide option on the grey menu.

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).
