The Lowdown
Alright folks, Rusty here. Let's have a look at what's brewing for the next couple of weeks at Molhes de Mampituba.
The outlook starts off a bit slow, but there's some real potential waiting in the wings. The first few days are pretty average, with a mix of onshore winds and messy conditions. We’ve got a solid run of surf coming, but you’ll have to be patient.
Saturday the 5th is a write-off. The morning is a small 3ft S swell, but with a cross-shore wind, it's just not worth the paddle. The afternoon turns even worse with a choppy 3ft S swell. Sunday the 6th pushes up to a decent 8ft S swell in the morning, and the wind is cross-offshore, cleaning it up nicely. The combined energy is a strong 1537, but the afternoon bumps up to 8ft S with a fresh cross-shore wind that will make it lumpy. Monday the 7th is your first real chance. The morning is glassy with a clean 5ft SSE swell (292 energy). The water temp is sitting at 63°, which is about average for this time of year. That’s a nice, clean session if you can get out.
Tuesday the 8th has a morning window with a clean 5ft ENE swell, but the period is a short 6 seconds, so it won't have much punch. Wednesday the 9th and Thursday the 10th are mostly poor, though Thursday morning has a glassy 2ft SSE groundswell with a long 15-second period, which is pretty but tiny. Friday the 11th is a mess with rain and short-period slop.
Now, the big stuff. Saturday the 12th and Sunday the 13th see a massive 12ft SE swell roll in, with combined energy readings of 3183 and 4194 – that's serious power. The period is 10 seconds, building to 12 seconds. This is *expert-only* territory. The swell is predicted to be too big for this break, and the winds are strong and cross-shore. This setup looks more interesting for kite surfing than paddle surfing. Do not be tempted.
The real standout comes on Monday the 14th. After the big swell drops, we get a glassy morning with a 7ft ESE groundswell at an 11-second period. The combined energy is a solid 1429. The wind is dead calm, making for perfect conditions. This is the best on offer for experienced surfers. The water should still be clean from the passing swell.
The rest of the second week is a slow fade. Tuesday the 15th is marginal, Wednesday the 16th is glassy but small at 4ft, and Thursday the 17th through the 20th offers a few small, clean windows, but nothing to write home about. The 20th has a clean 6ft E swell in the morning, which is a nice way to cap it off.
So, to sum it up: Monday the 14th is the absolute standout. Glassy, solid size, good period. Don't miss it. The weekend of the 12th is for experts only, and even then, it's a maybe. The rest is mostly small and clean, or windy and messy.
Rusty, signing off.
