The Lowdown
Hey everyone, Rusty checking in.
The water's sitting around 65°F, which is pretty normal for this time of year, nothing crazy.
So, here's the reality check: the first half of the forecast is a total bust. From Wednesday, July 29th, all the way through Monday, August 10th, it's a long, frustrating stretch of small, ugly surf. There's a tiny window on Thursday the 30th morning with a knee-high south swell (0.7m / 2ft) and clean conditions at Praia Cardoso, but the energy is weak. It's barely worth paddling out for.
The one day that makes this whole forecast worth talking about is Wednesday, August 12th. That morning we've got a serious 7ft south groundswell with a super-long period of 14 seconds. The energy reading is massive at 2872 – you'll feel the difference. With a light offshore wind, it's going to be clean and powerful. This isn't for beginners; this is for the experienced crew who know how to handle a heavy, organized swell. The afternoon gets even bigger, pushing 10ft, but the wind goes onshore and the period drops, making it messy.
The next day, Thursday the 13th, still has some size hanging around at 8ft, but it's shorter period and windier, so it's a step down. Still fun for those who want to chase leftovers, but not the standout.
In short, get ready for a lot of flat, quiet days, then a proper beast of a morning on the 12th. That's your window.
Rusty.
