The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’re looking at a pretty solid run of surf coming up at Praia da Baleia. The water is sitting at 72°, which is a touch warmer than normal for this time of year – nothing crazy, but you’ll notice it’s a little more comfortable than usual.
The week kicks off on Tuesday, 8th September. The morning is glassy with a clean 4ft swell from the south, period around 10 seconds. The combined energy is moderate at (420). It’s not huge, but with the wind dead calm and the water smooth, it’s going to be a fun, clean session. The afternoon sees a slight drop to 4ft, still glassy, still clean. A mellow start for the beginners – this is a beginner-friendly spot, and it’s fairly consistent here.
Wednesday morning the 9th gets a little messy with moderate rain, but the swell is 4ft from the ESE at 8 seconds. The wind is completely glassy again, so the surface will be smooth. The wave energy is still moderate (296). The afternoon brings heavy rain and a cross-off breeze, but the swell is 3ft – still surfable, but you’ll want a hood if the rain sticks around.
Thursday, 10th September, morning is a standout. Glassy conditions, 3ft of south swell with a long period of 12 seconds. That’s a groundswell, and it’s going to wrap nicely into the point. The combined energy is moderate (314). The long period also means fewer waves in the set, but the ones that come will have shape. Afternoon gets a risk of thunderstorms and a cross-on wind, so the quality drops.
Friday the 11th and Saturday the 12th are a bit of a write-off. Friday has cross winds and a small 3ft to 3ft swell, and Saturday drops to a tiny 2ft with poor, choppy conditions. Not worth paddling out, honestly.
Now, here’s where it gets interesting. Sunday, 13th September, morning sees a jump to 7ft from the south at 10 seconds. The combined energy hits strong at (836). But the wind is cross-on, so it’ll be a bit bumpy. Still, that’s some size for the beach and point setup. The afternoon is 6ft.
Monday, 14th September, is your top pick. Morning has 7ft from the ESE at a short 7 seconds, but the wind is cross-off and clean. The combined energy is strong (752). That’s a punchy, powerful wave for the point. The afternoon drops to 6ft but the wind goes cross, so it’s still a good go.
The rest of the week into the weekend keeps a steady 5ft to 6ft range, with glassy or clean conditions most days. Tuesday the 15th morning is glassy with 5ft, Thursday the 17th afternoon turns glassy again with 5ft, and Friday the 18th is all glassy with 5ft to 5ft. This is a good, consistent run.
Then a real standout pops up on Sunday, 20th September. Morning is completely glassy, zero wind, with a clean 5ft from the ESE at 9 seconds. Combined energy is moderate (349). That’s going to be a dreamy morning session.
Monday the 21st fades to 3ft and ordinary conditions, but don’t sleep on Tuesday, 22nd September. The morning delivers 6ft of south swell at 10 seconds, glassy with calm wind. The combined energy is strong (666). Then the afternoon bumps to 5ft at a very long 13 seconds, with a massive combined energy of (1072). That’s groundswell – it’s going to have some serious power, especially on the point. The afternoon wind is light cross, so it’s not perfect, but the energy is there.
Wednesday, 23rd September, keeps the 6ft south swell at 13 seconds through the morning, with light cross winds. The combined energy is still very strong (1069). By the afternoon, the wind goes glassy, and the swell is 5ft at 13 seconds – that’s a beautiful, long-period, clean afternoon wave. The combined energy is still strong (800).
Overall, the best bets are Monday, 14th September morning for the biggest, cleanest swell, and Tuesday, 22nd September morning for the glassy, powerful groundswell. The crowd is listed as “sometimes” here, so you might have company, but at a spot this consistent, it’s worth it.
Rusty.
