Morros dos Conventos Surf Forecast and Surf Report

Alright, let’s get this straight. We’re looking at Morros dos Conventos, that river mouth setup down there, and honest to god, the next 16 days are a real mixed bag. It’s inconsistent for a start, so we’ve gotta pick our moments. The water’s sitting at 61°, which is a bit colder than normal for this time of year – something like 3° off. You’ll want a thick wetsuit.

First real chance to paddle out hits on Thursday, September 10th. It’s small, we’re talking knee-high 2 to 3 ft from the SSE. That combined energy reading is actually solid at 403 and 336, so there’s some push, but it’s long period – 15 and 14 seconds – so it might be a bit too straight for the beach and river mouth zone. Winds are light cross and onshore, so it’s not glassy, but it’s not a complete write-off. It’s marginal, that one.

Friday the 11th is a write-off. Heavy rain, mod rain, cross winds, and the swell drops into the dirt. 1 to 2 ft from the SSE with energy barely hitting 44 to 77. Just leave the board in the car.

Now, Saturday the 12th is where it gets interesting, but also tricky. The swell jumps to a solid 7 ft from the S. The energy reading is 1112, which is strong to very strong. But the period is short – just 8 seconds – and the wind is a moderate cross-shore. It’s going to be lumpy. That’s a beast of a swell, but the quality is poor with the chop. I wouldn’t call it a standout for paddle surfing; this kind of setup with that much wind and a beach setup looks more interesting for kite surfing.

Sunday the 13th is the standout for the first week, no question. Morning session is the time. Swell is a clean 5 ft from the SE, moderate energy at 217, and the wind is glassy – dead calm. That’s a window of pure clean conditions. The period is short at 8 seconds, so it won’t be the juiciest, but glassy is glassy. It’s the best on offer.

The rest of that week gets messy. Monday the 14th is cross and choppy, Tuesday the 15th has a sneaky 3 ft cleanish morning from the SSE with energy at 455 (moderate) but it’s marginal. The afternoon gets smashed by 16 mph south winds.

Looking into the second week, we get a few clean windows. Thursday the 17th morning is a real gem – 4 ft from the SSE, period 12 seconds, and the wind is a light cross-offshore. That’s clean. The energy is 499, which is moderate. That’s another one to circle, but it’s a week away, so promising but not locked in. Friday the 18th morning is similar, smaller at 3 ft but clean with cross-off winds. Saturday the 19th morning is 2 ft from the SSE with a long 13-second period and clean light cross-off winds.

After that, it really fades. The 20th through to the 25th is mostly poor, with tiny swell, onshore or cross winds, and energy readings dropping into the double digits. A couple of tiny glassy moments on the 22nd and 24th, but we’re talking ankle-to-knee-high slop.

So, the two true standouts are Sunday morning the 13th with that glassy 5 ft, and a week later, Thursday morning the 17th with the clean cross-off 4 ft and longer period. The rest is for the desperate or the kooks. Signing off, Rusty.
