The Lowdown
G'day, Rusty here, lookin' at the surf for Molhes de Mampituba over the next couple of weeks. We've got a bit of a slow start, but there's some real fire in the back half of this run, so let's get into it.
The first solid surf we see rolls in on Wednesday, August 12th. It's not the biggest, but the conditions are a treat. Wednesday morning, we've got clean 6ft swell pushing in from the SSE, with a solid 12-second period and a light cross-offshore breeze from the NNW. The water's sittin' at 64°, which is pretty much what you'd expect for this time of year. The combined energy is a solid 788, so there's some grunt there. It's a good, clean day at the jetties. Wednesday afternoon holds up nicely too, with 5ft SSE swell and the same cross-off wind, so you can get a full session in. This is a good, solid start.
Thursday, August 13th, the swell bumps up a bit to 6ft from the SSE, but the wind swings around to a light cross from the SW, which is still okay. The energy jumps right up to 1336, so there's plenty of push, but the morning window is a bit of a mixed bag with the tide. Thursday afternoon sees the wind go onshore from the SE, and the energy drops, so it's a bit of a write-off. Friday, August 14th, and Saturday, August 15th, are looking pretty average. The wind is on it, choppy and messy, with the swell mixing up from the east. Not the kind of conditions you get excited about. The short period (8 seconds) on Saturday doesn't help.
Now, Sunday, August 16th, the swell is getting bigger, hitting 8ft from the ENE in the morning. The wind is cross-off from the NNE, and it's clean. The energy is 1310, but that 8ft is gettin' into the expert-only zone. It's a powerful wave, but you need to know what you're doin'. The afternoon drops to 7ft, but the wind goes cross, so it's less special.
Here's your standout moment. Monday, August 17th. This is the one. The morning is goin' to be absolutely magic. We've got a 8ft swell from the ENE, but the wind is glassy, dead calm from the NNE. The energy is 1155. It's a big, powerful wave, but with those glassy conditions, it's a dream for the experienced crew. This is the best session on offer, hands down. The afternoon goes to mush, so get it while you can.
After that, the week goes quiet. Tuesday, August 18th, the swell drops right off to 3ft, and the wind is light onshore. We get a run of small, poor surf from the 19th through the 22nd. The energy is low, the wind is cranky, and it's just not worth paddlin' out for. There's a bit of a dry spell, about 4-5 days of nothin' much.
But then the second week starts to show some promise. Sunday, August 23rd, the morning session looks like a ripper. We've got 6ft swell from the south, with a 12-second period and a clean offshore wind from the NNW. The energy is 884, and the conditions are described as "very good." This is a solid drop-in for the second week. The afternoon goes cross-on, so it's a one-hit wonder.
Monday, August 24th, keeps the run goin'. The morning has 5ft swell from the south, a cross-off breeze from the NNE, and clean conditions. The afternoon is an absolute gem – glassy calm, with no wind, and 4ft SSE swell. The energy is 956, so it's a good, fun wave. A perfect afternoon session.
Then we get the final standout for the run. Tuesday, August 25th, morning. This is for the experienced crew. The swell is 6ft from the SSE, but the period is 14 seconds, so it's a proper groundswell with heaps of energy (1212). The wind is glassy, dead calm. This is a powerful, clean wave that will be reelin'. It's a serious risk, but the reward is huge. The afternoon goes a bit cross-on, so the morning is the window.
The last few days, August 26th and 27th, wind down. The swell drops, and the wind gets messy. The 27th morning has a glassy 4ft, which is a fun little cleanup wave, but nothin' to write home about.
So, to wrap it up: the best of the best is Monday, August 17th morning for the big, glassy, powerful conditions. Then keep an eye on Sunday, August 23rd morning, and Tuesday, August 25th morning for some serious, clean groundswell. The rest of the time is a mix of average and small. Get out there when the wind is right, and you'll be smilin'.
Rusty.
