Costa Azul Surf Forecast and Surf Report

G’day, Rusty here. Let’s talk about what’s shaping up at Costa Azul over the next couple of weeks.

Right from Monday the 31st of August, we’ve got small swell rolling in – a 3ft SSW groundswell, period around 13 seconds, with decent energy (555). The water is a warm 88°, a solid 5° warmer than usual for this time of year, so you won’t need a wetsuit. The morning is clear with a light 5 km/h S wind, but it’s cross-on, so expect a bit of a bump. It’s marginal but surfable.

Tuesday the 1st September drops to 3ft from the SSW, with a very long 18-second period in the afternoon. But the wind is onshore and choppy – 15 km/h S cross-on. The energy is 544, but conditions are poor.

Wednesday the 2nd, the swell jumps to 8ft from the S, period dropping to 11-12 seconds. The morning has a strong 20 km/h ESE onshore wind, and the wave state is unknown – likely messy. The combined energy is massive – 2251 in the morning, 2077 in the afternoon. A lot of power, but the conditions are no good.

Thursday the 3rd and Friday the 4th, the swell hits 10ft from the S and SSW. Costa Azul is exposed, and at this size it’s too big, even with favorable tide and wind. The energy numbers are enormous – 2632, 4629, 3547. Only experienced surfers should consider it, and honestly, it looks more suited to kites.

Saturday the 5th, still 8ft to 9ft SW, with cross-on or cross winds at 15-20 km/h. Energy is still high (3212, 2634). Choppy and lumpy – a skip day.

Sunday the 6th afternoon is the first real highlight. The wind swings to a moderate 20 km/h WNW offshore, swell drops to 4ft from the SSW, with a 14-second period. Energy drops to 526. Suddenly it’s clean, lined-up, and rideable. This is a go.

Monday the 7th is glassy in the morning with 3ft SSW at 14 seconds, energy 466. The afternoon is cross-off with 3ft. Clean small waves.

Tuesday the 8th and Wednesday the 9th are all glassy conditions with very small swell – 2ft to 3ft, periods from 13 to 17 seconds. Energy is low (343 to 618). Perfect for a longboard, but the long-period swell will be slow, with long lulls. Best at the point or reef.

Thursday the 10th, a little bump to 4ft SW at 16 seconds. Light cross-shore and cross-off winds. Energy 616 to 665. Marginal but doable.

Now, the standout of the whole outlook – Saturday the 12th of September. The afternoon session is excellent. The swell is 4ft from the SSW, 13-second period, with a light 10 km/h NNE cross-off wind. The combined energy is 1074 – moderate but solid. The forecast says excellent conditions for experienced surfers. This is the one to mark on the calendar.

Sunday the 13th, back to 10ft from the SW – too big again, even with offshore wind. Energy numbers are huge (2644, 4493). Kite territory.

Monday the 14th through Tuesday the 15th, back to small, clean swell – 2ft to 2ft, SW, periods 16-18 seconds. Glassy or cross-off winds. Energy low (310 to 488). Fun little waves.

So, to wrap it up: the first week has a lot of either too small or too big swell with patchy wind. The two genuine standouts are Sunday 6th afternoon with offshore wind, and Saturday 12th afternoon with that perfect combo of size, period, and cross-off breeze. The second week tails off into glassy small waves. Aim for those two windows.

Rusty.
