The Lowdown
G'day, Rusty here, lookin' at the surf for the next couple of weeks. It's a bit of a slow start with no real surf to get excited about for the first few days, but there's a couple of windows that'll get the heart pumpin' if you're patient.
The first worthwhile surf doesn't show up until Monday, September 7th at Molhes de Mampituba. It's a river/jetty setup, and it's fairly consistent. The water is sittin' at 63°, which is about normal for this time of year, so nothin' to complain about. Monday morning, we've got a clean 4ft swell from the SSE, period around 9 seconds, and the wind is light offshore from the NW. That's a glassy, clean look. The combined energy is moderate at 294, so it's not a monster, but it'll be fun. Crowds are often here, so expect some company.
Tuesday, September 8th morning is another good one. The swell drops a touch to 3ft from the SSE, but it's still clean with a light cross-offshore breeze from the NNE. Combined energy is 314, so there's a bit of push. Again, crowds are likely, but the waves will be fun and clean.
Then we hit a bit of a lull. Wednesday, September 9th morning has a clean 4ft from the E with light cross-offshore wind, but the swell period is a shorter 8 seconds, so it's a bit weaker. Thursday, September 10th morning is glassy but only 3ft from the ENE. It's surfable, but nothin' special.
The real standout, the one you should circle on the calendar, is Tuesday, September 15th morning. The swell jumps to 5ft from the SSE, but look at that period—13 seconds, proper groundswell. The wind is a light offshore from the WSW, and it's comin' in clean. The combined energy is a solid 935 (moderate to strong). This is a long-period swell, so it'll be better shaped here at the jetty, with good energy and longer lulls between sets, makin' the paddle out easier. This is the best of the whole run.
Wednesday, September 16th morning is also worth a mention. It's glassy with a 3ft swell from the SSE, period 12 seconds, and clean conditions. Combined energy is 470. It's a good follow-up to Tuesday.
The second week has a few more mornings that look okay. Friday, September 18th morning has a clean 3ft from the SSE with a very long 15-second period, and Saturday, September 19th morning is clean with a 3ft swell from the SSE, 13-second period. Both are clean with light offshore winds, but the size is small. The big one is definitely Tuesday the 15th.
Rusty.
