Molhes de Mampituba Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s cooking at Molhes de Mampituba.

This is a river jetties setup, fairly consistent, exposed to the southeast. The water temp is sitting about average for the time of year, which is nothing to write home about, just standard winter stuff. We’ve got a bit of a wait for any real action, but the first half of the period has a couple of clean little windows that look fun. The biggest standout is Friday the 17th and Saturday the 18th.

Tuesday, July 14th – There’s surfable swell in the morning, around 5ft from the southeast with a short period of 10 seconds. The wind is light cross-off from the north-northeast, keeping it clean. Combined energy is 413, so moderate energy. It’s a decent little session but nothing huge. Afternoon turns messy with a cross-shore wind, so bail out before lunch.

Wednesday, July 15th – Swell drops back to 3ft from the east-southeast, period 9 seconds. Morning is clean with light cross-off winds, but it’s small – you’ll be on a groveler. Afternoon gets a little bumpy and marginal.

Thursday, July 16th – Morning offers 5ft from the northeast with a short 7-second period. Light cross-off winds make it clean, and energy is moderate at 435. The period is short, so it’ll be a bit lumpy and walled-up, but it’s surfable. Afternoon turns to junk with cross-shore wind.

Friday, July 17th (BEST) – This is the one to circle. Morning brings 6ft from the east-northeast, period 8 seconds. Wind is light cross-off from the north-northeast, keeping it clean. The combined energy jumps to 892, which is strong, punchy energy. This is solid intermediate stuff – not quite expert territory, but getting chunky. The swell direction matches the optimum SE swell direction reasonably well for this jetty setup. Expect some proper waves.

Saturday, July 18th (BEST) – Another standout. We get 7ft from the east-northeast again, period 9 seconds. Light cross-off winds all day – morning and afternoon are both clean. Energy is 931 in the morning and 936 in the afternoon, so strong, powerful swell. This is right in the intermediate sweet spot, but the crowd factor is listed as "often" so expect company. The quality should be very good, with clean faces and decent shape. This is your weekend winner.

Sunday, July 19th sees the swell drop back to 4ft with clean cross-off winds, but the energy drops to 290 – still surfable but nothing special.

Monday, July 20th is rainy with small 3ft swell and poor conditions. Not worth paddling out.

Tuesday, July 21st – Morning is interesting: glassy conditions with a light westerly breeze, and 3ft from the south with a *much longer* 12-second period. That’s a groundswell pulse. Combined energy is 397. The period is long so at a jetty setup, it could wrap in nicely, but it’s small. Still, glassy and clean – worth a look for the patient surfer.

From July 22nd through the 25th, things get messy. Strong cross-onshore winds, lumpy conditions, and only marginal or poor surf. There’s a brief glimmer of glassy conditions on Saturday the 25th afternoon with 4ft from the east-northeast, but the period is short (8 seconds) and energy only 274 – it’s a maybe.

The last few days, from July 26th to the 29th, see small, clean surf in the mornings with swell around 3ft from the south or south-southeast, periods 9 to 11 feet. It’s fun small-wave gear territory, but nothing that’ll pull you out of bed early. The 28th afternoon has a clean cross-off window with 3ft from the southeast, period 11 seconds, which is a nice little long-period groundswell – but tiny.

If you want the real deal, make a plan for Friday the 17th and Saturday the 18th. Clean, strong swell, and the jetties should focus it nicely. Don’t sleep on it.

Rusty.
