The Rock-Costa Azul Surf Forecast and Surf Report

G'day, Rusty here.

We've got a proper run of surf coming up at The Rock-Costa Azul, a reef setup that needs a south swell to really fire. The water is currently sitting at 88°F with a 5°F anomaly, which is much warmer than what you'd expect for this time of year, so you can leave the steamer at home.

The week kicks off with a sizeable, but messy, pulse on Thursday the 3rd. Swell is 8ft from the SSW with an 11-second period, but a cross-on southerly breeze at 9 mph is going to chop it up. The combined energy is a solid 2763, but it's not one for a paddle-out. Friday the 4th is more of the same in the morning – 7ft from the SW but still cross-on and choppy. The afternoon drops to 5ft, but the wind swings cross-shore, and with a 16-second period, the lines will be there, just not clean.

The standout window starts Saturday the 5th. Saturday morning sees the swell holding at 5ft from the SSW with a 16-second period, but the wind turns cross-offshore from the SW at 9 mph. The energy is still strong at 2085, and it's described as clean. By Saturday afternoon, the wind goes fully offshore from the W at 12 mph, with the swell at 6ft from the SW and a 13-second period. This is the pick of the first week – clean, punchy, and for experienced surfers only. Sunday the 6th keeps it clean with lighter cross-off and offshore winds, swell dropping to 4ft and 4ft, but still excellent.

Monday the 7th afternoon goes glassy with a 4ft WSW swell, though the period drops to 11 seconds, making it weaker at 851. The following week sees a steady drop in size, with a lot of glassy, clean conditions from Tuesday the 8th right through to the 17th. Most of these days offer knee-to-waist high, clean surf, so the longboard or a funboard will be the go.

The second real standout comes on the 17th and 18th of September. Thursday the 17th morning is glassy with a 2ft SW swell, but the period is a very long 21 seconds, pushing the combined energy up to 731. This is a proper groundswell, and given it's a reef, it will line up beautifully. Thursday afternoon holds with a clean 3ft from the SW at 21 seconds (884 energy). Friday the 18th is all glassy, with 3ft SW swell at 20 seconds and 19 seconds. This is a long-range forecast, so it's a promising one, but keep an eye on it – if it holds, it’ll be a dream session.

Crowds are listed as "often" here, so expect company, especially on those standout days. The consistency is good, so you won't be waiting long for a set.

Rusty.
