The Lowdown
Alright, folks, Rusty here. Let’s get into it. The forecast for our region is a bit of a mixed bag. We’ve got a solid window of clean surf coming up, but we’ll have to wade through some average, blown-out conditions to get to it. The early part of the week is looking pretty uninspiring, but there are a couple of days that are going to be worth circling on the calendar.
Right now, things are pretty flat and messy. We’re looking at some small, weak surf in the 2ft range, with the energy level sitting at a weak 104. Water temp is sitting at about 68°, which is a touch warmer than usual for this time of year, but nothing crazy. The wind is light, but the surf is too weak to get excited about.
The next few days are a bit of a write-off for quality. We’ve got some small swell, but the wind is all over the place, and the conditions are choppy or just plain poor. A lot of these days are showing cross-onshore winds and poor surf. We’ll see some 4ft to 5ft swell, but the energy is still weak to moderate, and the period is short, so it won't have much punch.
The first real spark of life shows up on the 15th of September. That Tuesday morning, we’ve got a cleaner forecast with a 6ft E swell and a light offshore wind. The energy jumps up to 496. This is looking like a fun one. The break here, `Barra do Sul`, is exposed and picks up that E swell well. It’s a fairly consistent spot, so it should be holding that size. The wind is light, which will keep it clean. That afternoon gets a bit windier with a bit more energy (576) but it’s still rideable.
The real standout, though, is looking like the 19th of September – that’s a Saturday. The morning shows a 6ft ENE swell with light cross-offshore winds and strong energy in the water at 687. It’s clean, and the 8-second period is workable. But the afternoon is where it’s at. The swell bumps up to 7ft, the energy jumps to a solid 993, and the wind goes light offshore. This is the biggest, cleanest swell of the period. It’s going to be a proper day. The 20th still has some decent leftover energy from that pulse, around 478, with glassy conditions in the morning, so Sunday could be a good follow-up.
There’s a bit of a lull after that. The energy drops off and conditions get a little messy again, with the wind shifting onshore. The surf gets smaller and weaker through the middle of the following week. There is a little blip of long-period swell at the very end of the forecast, around the 22nd and 23rd, with 14 and 13-second periods, but the size is tiny, only around 2ft to 2ft. Not enough to do much with.
So, to sum it up: If you want waves, your best bet is to wait for the 19th. That’s the standout day – biggest swell and cleanest conditions. The 15th is also worth a look, and the 20th has some decent leftovers. Everything else is either too small, too messy, or just plain flat. It’s a waiting game, but the good days are there.
Rusty out.
