The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Barra do Sul over the next couple of weeks.
Well, to be honest, it's a bit of a mixed bag. The good news is there's always some swell in the water, but the wind gods are playing hard to get. The best windows are going to be when the breeze drops or turns offshore, and we've got a couple of those to aim for.
First up, the standout session is on Monday, 14 September afternoon. The water is a touch warmer than normal for this time of year at 69°, which is nice. We've got a solid 6ft swell rolling in from the E, with a short period of 7 seconds. The real kicker here is the wind: a clean offshore from the WSW at 6 mph. It's going to be ripping, glassy walls. The combined energy is pumping at 710, which is a moderate to strong push. This is the one to circle on the calendar.
Now, before that, there's a few other sessions worth a paddle. The morning of Wednesday, 9 September has a 4ft E swell with an 8-second period, and the wind is glassy – completely calm, with a combined energy of 166. It's not huge, but if you want a longboard or a funboard, it'll be clean and fun. Then Thursday, 10 September, both morning and afternoon, are also glassy with 3ft E swell. The afternoon is dead calm, zero wind. Again, small but clean.
We also have a few promising long-range calls. The morning of Tuesday, 22 September has a 5ft E swell with an 8-second period, and a light cross-offshore wind from the SW at 3 mph. That's a clean setup, with a combined energy of 242. It's a bit far out, so keep an eye on it, but it looks good.
The rest of the fortnight is mostly junked up by onshore breezes, or the swell is just too small or messy. The morning of Sunday, 13 September sees a bigger 8ft SSE swell with a very long 13-second period, and combined energy is a massive 2549. But with a cross-shore wind of 16 mph, it's going to be a battle with a cross-chop. That's a kite-surfing day, not a paddle-surfing day. The period is so long it'll be hard to catch at a beach break anyway.
So, keep your eyes on the 14th afternoon. That's the best of the bunch. The other mornings I mentioned are worth a look for a clean, smaller wave. The rest of the weeks are mostly a write-off for quality surf.
Rusty out.
