The Lowdown
Alright folks, Rusty here. Let’s have a good look at what’s on the cards for the local stretch around Molhes de Mampituba. It’s a bit of a mixed bag, but we’ve got a couple of windows to get excited about.
First up, the water is sitting at 66°F right now, which is a touch warmer than normal for this time of year. That’s a nice little bonus for the early sessions.
The week starts off a bit messy. Sunday afternoon the 9th is a write-off – we’ve got a solid 7ft of south swell, but the wind is a cross-on mess and the energy is all over the place (1624). Not worth paddling out for. Monday the 10th isn’t much better with a similar story and a bit more size. You’re better off sitting this one out.
Now, the first real standout kicks off on Tuesday the 11th. The swell drops to a punchy 6ft from the SSE, period is a lovely 12 seconds, and the wind goes light and cross-off. That’s clean. The combined energy is still moderate (929), but the quality is there. Tuesday morning and afternoon are both looking good. Wednesday the 12th keeps that same vibe – 5ft, clean, cross-off winds. Warmer water, clean lines. This is the best of the week by a long shot. The break is a river/jetty setup, so it handles this kind of groundswell well.
Thursday the 13th is a step down. The swell is still around 5ft to 6ft, and the period stretches to 14 seconds, which is a solid groundswell, but the wind is a bit more variable. It’s a marginal call, but not a total loss. Friday the 14th drops in size and gets messy with cross-on wind. Saturday the 15th is tiny and glassy in the morning, with just 3ft – a fun little board option if you’re desperate.
Sunday the 16th through Monday the 17th sees a pulse of short-period easterly swell (8 seconds), around 5ft to 6ft. The wind is cross-off, so it’s clean, but the period is short. It’ll be a bit fat and won’t have the same punch as the earlier SSE swell. Tuesday the 18th and Wednesday the 19th are small and grotty. Don’t bother.
Thursday the 20th has a surprise – dead calm, glassy conditions and a little 4ft east-northeast swell. It’s not going to be epic, but if you want a glassy session on a small board, that’s your window. The energy is weak (276). After that, Friday through Saturday the 22nd is a total write-off with tiny, choppy junk.
But then, hold onto your board. Sunday the 23rd and Monday the 24th look promising. Sunday morning brings a new 5ft south swell with a 13-second period, clean cross-off winds, and moderate energy (768). That’s a solid, quality wave. Monday the 24th keeps it going with 6ft from the SSE, 12 seconds, and clean again. The winds hold cross-off into the morning. This is the second standout window, and it’s a long-range call, so keep your fingers crossed that the forecast holds.
Overall, the pick of the 16 days is Tuesday the 11th through Wednesday the 12th. That SSE swell with light offshore winds is the one. The late run on the 23rd and 24th is a close second, but it’s further out there.
Rusty.
