The Lowdown

Alright, let’s get into what’s on the menu for the local lineup.

The main spot that’s worth talking about is Molhes de Mampituba. This jetty break is fairly consistent, and when the conditions line up, it turns on proper. We’ve got a solid run starting this Monday, the 24th of August. That morning you’re looking at a clean 8ft swell from the SSE, with a long 14-second period between sets – that’s proper groundswell, packing some serious punch (combined energy 2114) – and a light cross-offshore breeze. That combo means clean, powerful wedges off the rocks. That size and power is for the experienced crew only; beginners should sit this one out. Water temp is about normal for the season.

Monday afternoon, the wind fouls up from the onshore side – not worth the effort.

Tuesday the 25th morning backs off to about 5ft from the SSE, 12-second period, still with clean cross-off wind. The energy is more moderate (680), but the wave shape should still be fun for an intermediate paddle.

Wednesday the 26th morning is another standout: 7ft from the SSE, 14-second period, clean off the north-west breeze. The energy jumps back up (1656). This one is for intermediates and above.

Thursday the 27th morning drops to about 5ft, but again you get a clean glassy window with a light cross-off. Good for a quieter session.

Now, Friday the 28th – this one is interesting. Morning brings 8ft of NE swell with a short 8-second period, but the wind is pure offshore from the NW. The energy is strong (1369) and the call is excellent conditions for experienced surfers. That offshore breeze will hold the faces up, but the short period might make it a bit fat or crumbly in the jetty current. Still, for the charging crew, that’s a serious contender. Experts only at that size.

After that, the swell fades fast. Saturday and Sunday bring smaller 4ft to 4ft east swell, but Sunday afternoon (30th) has a moment of glassy conditions with a 6ft ENE swell – that could actually be a fun surprise. The energy is moderate (902).

Then we hit a rough patch. From the 31st of August through the start of September, conditions look mostly poor.

The next real highlight is Wednesday, the 2nd of September. That morning is dead flat calm – zero wind – with a 6ft SSW swell. The period is only 8 seconds, which is a bit short, but glassy conditions mean the wave face will be clean and inviting. Good for intermediates.

Another lull follows until Monday the 7th of September morning, which brings a 5ft ENE swell with a very short 6-second period but clean cross-off wind – surfable but nothing to write home about.

And the one to really keep an eye on? Tuesday the 8th of September morning. That’s an 8ft ENE swell, short 8-second period, but with a light cross-off breeze and strong energy again (1493). That’s expert territory. If the jetty lines up, it could be one of those sessions you remember through the winter. It’s more than two weeks out, so don’t book the day off yet, but it’s got promise.

Best calls are the mornings of Monday the 24th, Wednesday the 26th, and that glassy Wednesday the 2nd of September. For the big-wave crew, Friday the 28th and Tuesday the 8th are the ones to watch. Crowds are common at Molhes de Mampituba, especially on the clean mornings, so plan accordingly.

Rusty.
