The Rock-Costa Azul Surf Forecast and Surf Report

G’day, Rusty here. Let’s have a look at what the next couple of weeks are serving up for The Rock-Costa Azul – a solid little reef setup that’s exposed to the south and likes a good SSW swell. The water’s sitting at 84°, which is a good three and a half degrees warmer than what you’d normally expect for this time of year – that’s pretty unusual, and it’s a treat.

Right now, things start off a bit ordinary. Sunday the 5th is a mixed bag – we’ve got a long-period 4ft SSW groundswell rolling in from 16 seconds, with a combined swell energy of 892 (moderate). But the morning has a light onshore wind, so it’s messy. The afternoon cleans up nicely with a light cross-off breeze, and the swell drops a touch to 4ft. It’s not huge, but it’s rideable and clean.

Monday the 6th sees the swell energy jump to 1242 in the morning (moderate to strong), still 4ft but with a cross wind – a bit of chop on it. The afternoon improves with 3ft at a very long 20-second period, cross-off wind, clean surface. That long period means better-shaped waves, but at a beach it can close out – on a reef like this, it should line up nicely.

Tuesday the 7th brings a little more size – 5ft in the morning, 5ft in the afternoon, both with 18-second periods and energy climbing to 1539 (strong). The morning has cross wind, but the afternoon delivers cross-off breezes. This is probably the standout window for the first week: consistent, solid groundswell, clean conditions in the afternoon, and that reef is going to handle the long-period stuff well. Crowds? Yeah, this spot gets ‘often’ busy, so expect company, especially when it’s pumping.

Wednesday the 8th holds 5ft in the morning but with a light cross-onshore – not ideal. Afternoon cleans up with 4ft and cross-off wind, but the energy drops to 947.

From Thursday the 9th through to Friday the 10th, things fade – dropping to around 4ft, periods shorten, and winds turn more cross-onshore. The energy dips into the 600s, and the quality is marginal. Not worth getting wet for.

Saturday the 11th is a bit of a sleeper – morning still average, but the afternoon picks up with 4ft, a light cross-off, and a clean surface. The scores say very good surf conditions, and it’s a promising end to the first week.

Sunday the 12th and Monday the 13th both have similar patterns – around 3ft to 4ft SSW swell, afternoons with light cross-off wind, clean waves. The energy sits in the 500–600 range, so it’s moderate but fun. Not a standout, but if you’re keen, the afternoons are your window.

Tuesday the 14th drops to 2ft but the period jumps back to 18 seconds – a long-period groundswell, just smaller. The afternoon is clean with 2ft and cross-off wind. Worth a paddle if you’ve got a log or a step-up.

Wednesday the 15th is pretty small – 2ft, cloudy, light breeze. Not much on offer.

Thursday the 16th morning brings 3ft SSW with light onshore – not great. But the afternoon? Glassy conditions, 3ft from the south, and a glassy sea state. That’s a rare treat for a reef break – clean as a whistle.

After that, Friday the 17th to Saturday the 18th turns ugly – winds pick up to 12–16 mph, cross to onshore, poor surf conditions, and energy around 500–600. Not worth it.

Sunday the 19th sees a brief return of 3ft with a 17-second period and cross wind – average. Monday the 20th, though, is a real gem: glassy morning, 3ft SW groundswell, 16-second period, and a glassy surface. Then the afternoon turns offshore with a light WNW breeze, clean and crisp. Energy sits at 662–708 (moderate). That’s the best on offer in the second week – a promising call, but keep in mind it’s eight days out, so the forecast could shift.

Overall, the standout windows are Tuesday 7th afternoon and Monday 20th afternoon – the 7th has more size and energy, the 20th has glassy-to-offshore wind. Both are clean options at a consistent reef break that handles the long-period stuff well. Crowds are likely at The Rock-Costa Azul, so get in early.
