The Lowdown

G'day, I'm Rusty, and I've got the goods on the local surf scene here.

Right off the bat, it's a bit of a slow start for us. We're looking at a stretch of nothing much for the first few days, with the first real chance of a wave coming on Saturday the 30th of August, but that's still a bit of a dud. The water's sitting at 61°, which is a bit colder than normal for this time of year, so you might want a slightly thicker spring suit.

The first shout-out that's actually got some spark is Monday the 31st of August in the afternoon at Molhes de Mampituba. The swell is a solid 7 ft from the east, with a short 8-second period, and the cross-off breeze from the north-northeast at 6 mph is going to keep it clean. The wave energy is pumping at moderate (1011), and it's a good one for experienced surfers. This spot is a river/jetty setup, so that short-period swell from the east might actually work well here. Keep in mind, crowds are often an issue, so get out there early.

Now, the real standout for the whole forecast is Sunday the 6th of September. The morning session at Molhes de Mampituba is a beast. We're talking a massive 13 ft swell from the south with a 13-second period, and the wind is a moderate cross-shore from the south-southwest at 12 mph. The combined energy is very strong at 7144, but truth be told, this break is a river/jetty, and that swell is just too big for it – it's a big-wave spot for experts only. The afternoon is a no-go with onshore winds.

Following that, Monday the 7th of September morning is another big one. A 10 ft swell from the south-southeast, with a very long 16-second period, and a clean cross-off breeze from the north at 6 mph. Energy is very strong (4288), but again, it's predicted to be too big for this break. That long-period groundswell is going to be a beast, and at a spot like this, it might just close out.

If you're looking for something a bit more manageable, don't sleep on Tuesday the 8th of September. The morning has a 7 ft swell from the south-southeast, with a 13-second period, and a clean cross-off from the north-northeast at 6 mph. The energy is strong (1365), and it's being called excellent for experienced surfers. The afternoon on the same day is even better, with glassy conditions, a light breeze from the east-northeast at 3 mph, and a 6 ft swell. That's a top-tier option.

After that, things settle down a bit. The 12th of September Saturday morning has potential with a 7 ft swell from the east, glassy conditions, and a light breeze. It's a good option but nothing like the big days.

So, to wrap it up, your best bet for a solid, clean session is the afternoon of Monday the 31st of August or the all-day session on Tuesday the 8th of September. The big swells on the 6th and 7th are for the brave and the expert crew only. Keep an eye on the forecasts, because things can change, but for now, that's the lay of the land.

Rusty.
