The Lowdown
Howdy, Rusty here. Let’s talk about Zippers-Costa Azul (beach and reef). It’s starting quiet, but if you hang tight there’s some proper juice coming. The water’s sitting at a very warm 32°, much hotter than what’s normal for this time of year, so go light with the wetsuit.
Tuesday the 18th kicks off with a clean 3ft SSW swell and a light cross-off breeze. The combined energy is a moderate 461 – not huge, but tidy. Tuesday afternoon the wind bumps up to a moderate breeze from the WSW at 12 mph, still clean but tide might mess with things. Wednesday the 19th is a bust with small cross-on wind and only 3ft SSW. Thursday afternoon the 20th is better – 3ft SSW groundswell, clean, energy at 391. Small but surfable.
Now, Saturday afternoon the 23rd is a sneaky one: a 2ft SSW groundswell with a long 18-second period, clean cross-off wind, and energy at 613. That long period will stretch things out on the reef, giving you some nice shape.
The real standout is Friday afternoon the 28th. Glassy conditions, 4ft SSW groundswell, 16-second period, and the energy is cranking at 955 – that’s solid, powerful surf. The wind is dead calm, so it’ll be as clean as it gets. This is the best window of the whole forecast. Saturday the 29th goes even bigger – 5ft SSW, glassy again, energy hits 1077 – that’s expert-only territory. Too big for beginners or most intermediates, but for the crew who can handle it, it’ll be firing.
Sunday the 30th holds strong at 4ft SSW with a clean cross-off afternoon wind, and Monday the 31st is smaller but clean in the morning. Early September looks shaky: Tuesday the 1st has glassy conditions but only 3ft short-period SSE windswell, and by Wednesday the 2nd the wind cranks up to a fresh cross-onshore breeze at 22 mph with lumpy 5ft to 6ft southerly swell. That’s more for kite surfers than paddle surfers.
Bottom line: the first week is about picking your moments, but the real magic is Friday the 28th and Saturday the 29th. Don’t miss it.
Rusty.
