The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the line for us.

We’ve got a pretty solid run of surf ahead over the next couple of weeks, but it’s not all clean and perfect. The standout window is shaping up around the 13th (Monday) and 14th (Tuesday), with some real nice conditions on offer. The water’s sitting at 58°F right now, which is a whopping 5°F colder than normal for this time of year – that’s a serious chill, so don’t be shy with the thickest wetsuit you’ve got.

The first call is for Molhes de Mampituba (river/jetties) on Monday morning, the 13th. We’ve got a clean 4ft swell from the SSE, with a light cross-offshore breeze from the WSW at 6 mph. The wave energy is on the weaker side for the morning (272), but the conditions are clean, and the offshore wind will make for some nice lines. Things get a bit more interesting Monday afternoon as the swell bumps up to 5ft from the SSE, and the energy jumps to moderate (566), but the wind swings onshore, making it choppy, so stick to the morning.

Tuesday morning, the 14th, is the pick of the early week. Swell pushes to 5ft from the SE, with a 10-second period, and the wind is a clean cross-off from the N at 9 mph. The wave energy is moderate (413), and the conditions are clean. This is the session to circle on your calendar. It’s a bit much for beginners at that size, but strong intermediates and up will have a ball. The afternoon turns to junk with a strong NE cross-breeze at 16 mph, spoiling the shape.

We’ve got a gap in quality on Wednesday and Thursday mornings, but nothing to complain about – you can still get waves. Wednesday morning the 15th has a clean 3ft from the ESE with light N winds, and Thursday morning the 16th has a punchy 5ft from the ENE, but the period is a short 7 seconds, so it might be a bit lumpy and weak. The energy is moderate (476) though.

Now, Friday the 17th is a big one, but with a catch. The swell jumps to 7ft from the NE with a 9-second period, and the wave energy is strong (1056). That’s a powerful, clean morning with a cross-off breeze from the NNE at 12 mph. This is expert territory at that size. The tide might make things a bit tricky, but for the big dogs, this is a serious session. Saturday the 18th keeps the size at 7ft in the morning, still clean, but the energy is dropping (960). It’s still a solid day for the experienced.

After a brief lull in quality, we get another standout in the second week. On Wednesday the 22nd, the afternoon session looks magic. The swell is 4ft from the SSE, but the period is a long 12 seconds, and the wind goes cross-off from the NNE at 6 mph. The wave energy is moderate (651). That’s a recipe for some beautiful, lined-up waves. The following Sunday, the 26th, also has a very clean morning with a 4ft SE swell, long 12-second period, light cross-off from the WSW, and strong energy (594). That’s a treat.

The very last standout is Monday morning, the 27th. Swell is 4ft from the SE, with a very long 13-second period, and a clean cross-off from the N at 9 mph. The energy is strong (756). That’s a classic long-period groundswell, and at a river mouth like this, it could be absolutely ripping with clean, long walls. The 28th also has a glassy morning with a 5ft swell from the NE.

So, your best bets: Tuesday morning, the 14th, for the best combination of size and clean conditions, and Monday morning, the 27th, for that long-period groundswell promise. The 22nd afternoon and 26th morning are also top-tier. Stay warm, and I’ll see you in the water.

Rusty.
