The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer at Praia da Baleia over the next couple of weeks.
It’s a pretty slow start, I won’t lie. The first few days we’ve got little waves around, but they’re small and the conditions aren’t quite there to make it worth paddling out. The water is sitting at 71°F which is a touch warmer than we’d expect for this time of year, so that’s a nice bonus if you do get wet.
We’re looking at the 29th of August, Saturday afternoon, with a tiny 3ft swell from the ESE, period at 7 seconds. The energy is weak (113) and honestly, it’s just ordinary. It’s glassy though, so if you’re desperate for a float, you can get out there. Sunday the 30th and Monday the 31st are similar – small, messy, not worth getting excited about. Tuesday the 1st of September, the morning is still poor, but the afternoon cleans up nicely with glassy conditions and a 3ft swell from the east, period 9 seconds. The energy picks up a bit (212) and it’s looking good for a few fun ones. Not a standout, but a nice little window.
Then we hit a bit of a bump. Wednesday the 2nd of September sees the swell jump to 8ft in the morning from the SSW, but it’s cross-shore and a bit choppy. The energy is moderate (626). That’s getting too big for beginners, and the condition isn’t great. By Thursday the 3rd, it’s dropping, but still cross-on. Not the best.
Now, here’s where it gets interesting. Friday the 4th of September, morning session: flat calm, glassy, 4ft swell from the SE with a period of 10 seconds. Energy is moderate (256). This is your first real look at a clean, surfable wave. It’s not huge, but it’s clean and the conditions are perfect. That’s a good one.
We get a bit of a lull over the weekend, with small clean waves on the 5th, but nothing to write home about. Then Sunday the 6th of September, the swell cranks up to 10ft from the south with a long period of 12 seconds. That’s a big groundswell, and the energy is strong (2382). This is expert territory. Too big for most, and the wind is cross-on, making it a bit messy. Monday the 7th of September morning is the real standout. Glassy conditions, 7ft from the south, period 12 seconds. The energy is strong (1119). This is going to be excellent for experienced surfers. The long period means the waves will have plenty of punch and shape, and with glassy conditions, it’ll be clean. This is the best on offer.
Tuesday the 8th of September afternoon is also a cracker: glassy, 6ft from the SSE, period 13 seconds, energy 1218. Excellent conditions for experienced surfers again. Wednesday the 9th of September keeps that run going with glassy conditions and 6ft to 5ft from the SSE, period 14 seconds. Very long period groundswell, so the waves will be powerful and well-shaped, but at a beach break it might be a bit straight. Still, for the experienced crew, it’s a fantastic run.
The second week settles down a bit. Thursday the 10th is clean, with 4ft from the SSE, period 13 seconds. Good for a fun session. The weekend of the 12th and 13th of September sees glassy conditions and 4ft to 5ft from the SSE, period 11-12 seconds. Consistent, clean, and fun for everyone. A solid end to the outlook.
So, to wrap it up: the standout is Monday the 7th of September morning, with 7ft south swell, 12-second period, and glassy conditions. That’s the one to circle. The secondary highlight is Tuesday the 8th and Wednesday the 9th of September, also glassy with solid groundswell. The rest is a mix of small, clean waves and a few bigger, more challenging days. No crowds mentioned, so you might have it to yourself.
Rusty.
