The Lowdown
Right, let’s have a look at what’s cooking over the next couple of weeks for Molhes de Mampituba (river/jetties). It’s a mixed bag, with a fair bit of waiting around, but there are a couple of windows that’ll get the blood pumping.
The water’s sitting at 61°, which is a bit colder than normal for this time of year, so you’ll want a decent spring suit.
The first few days are pretty grim. Thursday morning, the 10th, is a write-off – tiny 3 ft south-southeast swell with a cross breeze, and the combined energy is weak (389). Thursday arvo is no better, onshore junk. Friday the 11th is a mess of rain and wind, with a short, weak 3 ft easterly swell (217 energy). Saturday the 12th sees a jump in size to 7 ft from the south, but the wind is cross and cross-onshore, making it choppy and messy (moderate energy around 944). Not worth paddling out.
Then, on Sunday morning the 13th, we get a little glimmer. The wind goes dead calm – glassy as – and there’s a 5 ft southeast swell with a period of 8 seconds. The combined energy is moderate (267). It’s not a monster, but clean, glassy conditions at a river jetty setup are a treat. This is the best call in the first week. The swell is a bit short-period, but with the wind flat, you’ll get some fun little runners. Crowds are often here, so expect company.
The rest of the week fades again. Monday the 14th and Tuesday the 15th are mostly cross-shore slop and chop. Not great.
Now, we skip ahead to Thursday the 17th. The morning shows promise with a 4 ft south-southeast swell, a long period of 12 seconds, and a light cross-offshore breeze from the north-northeast. The combined energy is moderate (472). That long period groundswell will wrap into the jetties nicely, offering better shape and longer gaps between sets. It’s a good session for intermediates.
Friday the 18th morning is the real standout. We’ve got 5 ft from the east-northeast, a short period of 7 seconds, but the wind is light cross-offshore from the north-northeast, making it clean. The combined energy is moderate (575). It’s a solid, punchy swell for the jetties, and the conditions are described as very good. This is the best on offer in the entire forecast. It’s not huge, but it’ll be fun and workable.
Further out, Saturday the 19th morning has a clean 2 ft south-southeast long-period swell (13 seconds) with light cross-offshore wind, but it’s small. Thursday the 24th morning goes glassy with a 5 ft easterly swell, but it’s short period.
The real big one is on Friday the 25th. The morning shows an 8 ft east-northeast swell with a period of 8 seconds, light cross-offshore wind, and very strong combined energy (1218). That’s for experienced surfers only – it’s too big for beginners. The afternoon pushes it to 10 ft with massive energy (2152), but the wind is onshore and the file says it’s predicted to be too big for this break. That afternoon session is a no-go for paddle surfing; it’ll be more of a kite show.
So, to sum it up: the first week is a struggle. The two best windows are Sunday morning the 13th (glassy, small but clean) and Friday morning the 18th (clean, solid, consistent). The 25th is for the experienced crew only, and only the morning. Pick your moments.
