The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for Barra da Lagoa over the next couple of weeks.
To be straight with you, the next 16 days are looking pretty quiet. There’s a big gap with nothing worth paddling out for from now until the morning of the 5th of August. That’s a long stretch of flat or tiny, messy conditions. You’ll be waiting over a week for the first real chance to get wet.
The water temperature is sitting at 65°F right now, which is about average for the time of year here. Nothing wild.
The first day that even starts to look interesting is the morning of Tuesday the 5th of August. We’ve got a modest swell filling in from the SSE, about 4ft, with a period of 10 seconds. The combined wave energy is moderate, sitting at 267. The wind is light from the north, so it’s cross-shore, creating small crossing ripples. It’s not perfect, but it’s the best we’ve seen in a while. The afternoon gets blown out by a NNE breeze at 12 mph, making it choppy and onshore, so that morning window is the one to aim for.
Then on the morning of Thursday the 7th of August, we get a small window of glassy conditions. Swell drops to 3ft from the SSE, period at 9 seconds, energy at 185. The wind goes glassy from the WSW at just 3 mph. This is about as clean as it gets, but the waves are small. It’s surfable, but you’ll be working for it.
Honestly, there’s no standout session in this forecast. The best on offer is that Tuesday the 5th of August morning, with a bit of size and shape, but the wind is not ideal. For the rest, it’s either tiny, too windy, or flat. If you’re a beginner, the small stuff on the 7th might be okay, but nothing here is firing. Keep an eye on the forecast, because it can’t stay this quiet forever.
Rusty.
