The Lowdown

Right folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks. We're talking about Molhes de Mampituba, a river/jetty setup that's fairly consistent and exposed to the south-east swell. The water temp is sitting around 63°, which is bang on average for this time of year, so nothing out of the ordinary there.

The first few days are a bit of a write-off, to be honest. Saturday's got a 3ft swell from the south, but the wind is all over the shop and it's going to be a messy, choppy affair. Not worth paddling out for. The combined energy is weak too, only 227 (moderate wave energy). Sunday morning, however, is where we start to see some life. A clean 8ft swell from the south with a good WSW cross-off wind. That's a solid size, getting a bit much for beginners, but for the experienced crew, it's a proper window. The combined energy jumps to 1628 (strong wave energy), which has some real grunt behind it. The wind is clean, so it should be a good session, but watch the tide – it's a bit of a question mark.

Monday morning is a nice little window. A 4ft swell from the SSE, with a clean offshore north wind. It's a bit smaller, but it's clean. Thursday morning the 10th is a real standout. The wind goes totally glassy, with a 3ft swell from the SSE, but the period is a long 15 seconds. That's proper groundswell energy, and it'll be hugging the jetties nicely. The energy is 399 (moderate wave energy), but the glassy conditions make it a top pick for a morning session. Crowds are often here, so be ready for some company.

Now, the second week has a couple of absolute rippers. Saturday the 12th afternoon turns it on: a 7ft swell from the SE, with a 12 mph offshore wind from the NW. That's a clean, powerful offering with combined energy of 1209 (strong wave energy). The size is getting up there, though, so it's for the experienced surfers only. The following Sunday the 13th afternoon is a beast, but a word of caution: the swell is predicted to hit 13ft from the SE with a 12-second period. The combined energy is a massive 4625 (very strong wave energy). That is a lot of water. The wind is cross-off, so it'll be clean, but the forecast suggests it's too big for this break. Only the absolute top end of local chargers should even look at it. It's a serious lot of water.

After that, things settle back down. The 18th Friday morning looks very promising: a 3ft SSE swell with a 13-second period, clean north-north-east wind, and combined energy of 607 (strong wave energy). That's a quality, long-period groundswell on a clean face. It's a great option for a Friday morning surf. Then, the 20th Sunday morning is a real gem for the end of the forecast. A 7ft swell from the ENE with a glassy north wind. The period is a short 7 seconds, but the glassy conditions and the size make it a very attractive option. The combined energy is 770 (strong wave energy).

So, the standout sessions are the Sunday morning the 6th for a solid, clean swell, and the Thursday morning the 10th for the glassy, long-period groundswell. The 18th and 20th are also very solid options in the second week. Keep an eye on the tide, and don't be afraid of the crowds. It's going to be a mixed bag, but there are some real classic moments to be had.

Rusty.
