The Lowdown
Right then, let’s have a look at what Praia Cardoso is offering over the next couple of weeks.
It’s a bit of a frustrating run if I’m honest. The next week or so is going to be a real test of patience. The swell is either running too big or just not offering much in the way of quality. The water temperature here is sitting at 66°, which is about average for the time of year. For the first ten days or so, we’re looking at a lot of marginal conditions and frankly, poor surf. There’s a real gap in the action.
However, things start to shift by the morning of Tuesday the 25th. That’s your first real window. With a 7ft swell from the south and a 12-second period, it’s got a bit of energy. The wind is light and cross-offshore from the NNE, so the surf is clean. This one is for the experienced crew though, as it’s a fair size for the beginner.
Then, hold onto your boards for Sunday the 7th of September. That is the standout session on offer. The morning is absolutely glassy, with zero wind, and a solid 6ft swell from the southeast. The period is a bit short at 7 seconds, but there’s a decent amount of energy in the water. That glassy condition makes it look like a dream. The afternoon is a different flavour, but still good, with a 3ft south swell and clean offshore winds from the northwest.
So, the best of the run is undeniably Sunday the 7th of September. The morning glass-off with a chest-to-head high southeast swell will be the one to wake up for. Keep an eye on the window on Tuesday the 25th too, but the real gold is that first Sunday of September. The crowd factor is "sometimes" at this spot, so you might have company, but with conditions like that, it’ll be worth sharing the lineup.
