The Lowdown
Alright folks, Rusty here with a look at what’s coming up for Molhes de Mampituba.
We've got a bit of a slow start, but the second half of the window is where the real action is. The first few days are pretty ordinary, with tiny, weak swell and onshore winds messing things up. Hang tight, because the weekend of the 8th and 9th is when things start to get interesting.
Right now, Tuesday the 4th, it’s small and messy. A 3ft SSE swell with a 12-second period is there, but the cross-on wind is killing it. The combined energy is a weak 284, so there’s not much to get excited about. Wednesday the 5th will see the swell drop to 2ft, but the morning will be glassy. It’s not going to be pumping, but it’ll be clean for a little paddle.
The first real standout is Saturday, August 8th. Saturday morning we’ve got a solid 5ft S swell rolling in with a long 12-second period, pushing a strong energy reading of 817. The wind is cross-off from the NNE, so the waves will be clean. By the afternoon, it gets even better – glassy conditions and a 5ft SSE swell. This is the best day in the near-term by a long shot. Sunday the 9th stays chunky with a 6ft S swell and a massive energy reading of 1315, but the cross-shore wind will put a bit of a chop on it.
After that, there’s a bit of a lull but it stays rideable. Then we get another standout window. Thursday, August 13th is looking prime. A 5ft ENE swell rolls in with glassy conditions in the morning and a good energy reading of 555. That’s a winner. Then, keep an eye on Tuesday, August 18th. By the afternoon we’re looking at a 8ft SSW swell with a very long 13-second period, and the energy is off the charts at 2637. This is a big, powerful groundswell. For a river/jetty setup like this, that long period could mean some real nice, lined-up waves, but it's going to be a big, powerful wave. This is for experienced surfers only.
The water temp is sitting at 66°F, which is a touch warmer than usual for this time of year.
Overall, the standout calls are Saturday August 8th for the most consistent, clean conditions, and Tuesday August 18th for the biggest, most powerful swell of the period.
Stay keen,
Rusty
