The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Balneario Novo Quintao. Straight up, it’s a tough run ahead. This spot is inconsistent at the best of times, and this 16-day window is a real mixed bag with a lot of wind and rain to deal with. The water’s sitting at 63°, which is a touch warmer than normal for this time of year.
The first real chance to get wet comes in on Tuesday morning, the 11th of August. We’ve got a solid 6ft swell rolling in from the SSE with a 12-second period, giving a moderate surge of energy (826). The wind is light from the east, which is workable, but the call is that it’s marginal. The afternoon sees the swell bump up to 6ft and the energy climbing to 1011, but the wind shifts a touch onshore, making it less inviting. It’s not a total write-off, but you’ll be working for them.
Then the wheels fall off. From Wednesday the 12th right through the weekend, it’s a mess. The wind is up, mostly cross-onshore, with rain. The surf is there, between 5ft and 7ft, but the quality is poor. That Saturday morning the 15th has a 7ft east swell, but it’s a short period of 8 seconds and a strong cross-onshore breeze. That’s a lumpy, messy combo that’s only going to look good for the kite crew.
We get a bit of a tease on Monday the 17th of August. The morning shows a big 10ft swell from the ENE with a 9-second period and a massive 2156 energy reading. The wind is light onshore, and it’s still marginal. That’s a lot of water for the beach/pier setup, and with that short period, it’s going to be a washing machine. This is strictly for the experts only, if anyone is brave enough.
The second week is a slow grind. Tuesday the 18th is a drop-off, with the swell down to 4ft and a cleaner look with a light offshore wind, but the energy is weak (275). You might find a few lined-up ones, but it’s a struggle. The rest of the week is more of the same: small, weak surf and mostly onshore winds. The standouts in this whole period are the mornings of the 20th and 21st of August. On the 20th, Thursday, we get a clear sky, a strong offshore wind from the WNW, and a tiny 3ft east swell. It’s clean, but it’s a knee-slapper. The 21st, Friday, is the best of the bunch. The swell is still small at 3ft, but it’s from the south with a 10-second period, and the wind goes glassy in the afternoon. That’s the window for a longboard or a funboard on a clean, tiny wave. The energy is still low (168), so don’t expect power.
The final few days from the 22nd to the 26th are a mix of small, weak swells and onshore winds. The morning of the 24th, Monday, is glassy with a 4ft ENE swell, but it’s short period and weak. The surfable waves are there, but they’re very ordinary. The last real pulse of energy comes in on the 26th, Wednesday, with a 6ft SSE swell and a 13-second period, giving 1454 energy, but the wind is cross-onshore and choppy, spoiling it.
Overall, there’s no true standout here. The best bet is the glassy afternoon on the 21st of August for a clean, small wave session. The Monday the 17th has the size for the brave, but the conditions are against it. Stay patient.
Rusty.
