The Lowdown
Alright folks, Rusty here. Let's have a look at what's shaping up at The Rock-Costa Azul.
The whole period is looking pretty consistent, with a solid run of clean, rideable waves from a south-west groundswell. The water is sitting at 88° – that's much warmer than normal for this time of year, so you can leave the steamer at home.
We kick off on Monday, September 7th with a beauty. A 4ft SSW swell, with a long 14-second period, is met with glassy conditions in the morning. The energy is solidly in the moderate range (785). This is a proper reef break, and when it's clean like that, it's a standout session for experienced surfers. The afternoon shifts to a lighter 3ft SSW swell with a cross-off breeze, but the quality holds. This is the best offer you'll get all week.
The rest of the first week keeps the momentum. Tuesday morning (Sept 8th) is a bit smaller at 3ft with a cross-on, but Tuesday afternoon cleans up again. Wednesday afternoon (Sept 9th) through to Friday morning (Sept 11th) serves up waist-to-chest high waves with mostly light winds, either glassy or clean. Friday morning in particular is a glassy 4ft SSW swell – very good. Crowds are likely at this spot, so get in early.
The second week starts to taper off a little in size. September 12th and 13th see smaller 2ft to 3ft swells, but with glassy, calm conditions, they'll be perfect for a longboard. You'll get clean fun waves. A bit later in the month, from around the 17th through the 22nd, we see another pulse of energy. The 18th of September offers a clean 3ft SW swell with a very long 19-second period, combining for moderate energy (645) – excellent quality at this reef. The 20th and 21st also look very promising with glassy mornings and clean afternoons, with swell sizes bumping back up to 4ft.
Overall, the standout is the opening Monday, Sept 7th, for the combination of size, direction straight from the optimum S direction, and that morning glass. The whole first half of the period is a ripper, with a notable second window of quality around the 18th to 21st. This break is consistent and will deliver.
Stay stoked,
Rusty
