The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day window for Molhes de Mampituba, and it’s a bit of a mixed bag. The first few days are a write-off, so don’t bother paddling out until Monday the 7th.
The real standout is the run from Saturday the 12th through Monday the 14th. That’s where the magic is. Saturday morning the 12th is looking prime: a clean 7ft swell from the SE with a period of 9 seconds, and the energy is pumping at 986. The wind is glassy, so you’ll be looking at clean lines. The afternoon jumps up to 8ft, but the wind is cross-off, which keeps it rideable. The energy is strong at 1283. This is the best window for intermediate and advanced surfers.
Sunday the 13th is a beast, but it’s for experts only. The morning sees a 8ft SE swell, but the onshore wind is going to chop it up. By the afternoon, it’s a 10ft swell from the SE (1634 energy), but the file says it’s too big for this break, so I’d give it a miss unless you’re a local charging hard. Monday the 14th morning is similar – 10ft with cross-off wind, but again, too big for the spot. The afternoon of the 14th, however, is a gem: 8ft from the ESE, clean cross-off wind, and the energy is still strong at 1442. That’s excellent for experienced surfers.
Before that, Sunday the 6th is a skip. 8ft from the S with a short 9-second period and 12 mph cross-off wind, but it’s marginal. The afternoon is a no-go with 7ft and strong cross-shore wind. Monday the 7th morning is a nice surprise: 5ft from the SSE with a 10-second period, glassy wind, and good energy (375). That’s a solid morning session. The afternoon gets cross-on and messy.
Tuesday the 8th morning is clean with 4ft SSE swell and cross-off wind, but it’s small. The afternoon is a chop-fest. Wednesday the 9th morning is a glassy 3ft SSE swell with a long 11-second period. That’s a clean, small wave session for the longboard. Thursday the 10th morning is glassy again, but only 3ft from the SSE with a very long 15-second period. It’ll be clean, but that long period will make it break a bit straight at the jetties.
After the big swell window, Tuesday the 15th is still okay for the morning with 6ft from the SSW and cross-off wind, but it’s a bit marginal. Wednesday the 16th morning is back to glassy with 3ft SE swell and a long 11-second period. That’s a nice, clean small wave morning.
The final few days are a bit of a gamble. Saturday the 19th afternoon looks okay with 4ft from the ENE and glassy wind, but it’s a short 7-second period. Sunday the 20th morning is clean with 3ft from the E, but again, small. Monday the 21st morning has a 5ft E swell and cross-off wind, but it’s marginal.
For the water temp, it’s about average for this time of year, so don’t expect any surprises.
So, overall, the best bet is Saturday the 12th through Monday the 14th. Saturday morning is the pick for clean, fun waves. The afternoon of Monday the 14th is for the experienced crew. The rest of the window has some small, clean windows for the loggers, but nothing that’s going to get the heart racing.
Rusty.
