The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks. It’s a bit of a slow burn, but there’s a couple of real gems hiding in the back half of the forecast.
Right now, we’re looking at the river mouth at Molhes de Mampituba. It’s a fairly consistent spot, exposed to the south-east, and it’s a touch warmer than normal for this time of year, with the water sitting at 65°.
The first real chance to get wet kicks off on Tuesday, August 4th. The morning is looking prime with a glassy calm, offshore breeze from the NW at 3 mph. The swell is a clean 3 ft from the SSE, running on a 12-second period. That’s a proper groundswell with some energy in the water (286). The afternoon holds the same, glassy and clean. It’s not big, but it’ll be clean and fun.
Wednesday the 5th and Thursday the 6th offer more glassy mornings, but the swell is a bit smaller at 3 ft and 2 ft, and the energy drops off (147 and 109). Surfable, but nothing to get excited about. Friday the 7th morning is tiny and glassy, but the afternoon gets blown out with a fresh 19 mph southerly wind.
Now, here’s where it starts to get interesting. Saturday, August 8th, the morning is a standout. The wind is light and cross-offshore from the NE at 3 mph, the swell is 4 ft from the south, but the period hits 12 seconds and the energy jumps to 570. It’s clean, and the report says it’s very good. The afternoon has a bigger 5 ft swell from the SSE with a 14-second period, pushing the energy to 1071, but the wind swings to a cross-shore and the rating drops. The morning is the session.
Monday, August 10th, is the big one for the experts. The morning sees a solid 8 ft south swell, with a 10-second period, and the energy is massive at 2040. The wind is cross-offshore from the west at 9 mph, keeping it clean. This is an excellent session but it’s big and powerful – over 8 ft, so this is for the crew with the skills and the board control. The afternoon is also clean but the wind picks up to 19 mph, so it’s more of a battle.
The 11th and 12th offer more clean conditions, but the swell drops back to 5 ft and 4 ft. The 13th Thursday morning has a glassy 5 ft SSE swell (474 energy) – a good, clean option.
Then, Friday, August 14th, is the other real standout. The morning is looking excellent with a 6 ft SSE groundswell, a 14-second period, and energy at 1190. The wind is a gentle cross-offshore from the NNE at 9 mph, keeping it clean. This is another one for the experienced crew, as the energy is solid and the period is long.
The 15th and 16th see a shift to a shorter period east swell (7-8 seconds). The 15th Saturday morning has a clean 6 ft swell from the east (593 energy), and the 16th Sunday morning is glassy with a 6 ft east swell. After that, the 17th and 18th are a mixed bag of cross-shore winds and average conditions. The 18th Tuesday morning has a 6 ft ENE swell but the wind is a cross-shore, so it’s not the pick.
So, for the best on offer, I’d be circling Saturday morning, August 8th, for the clean, fun conditions, and then Monday morning, August 10th and Friday morning, August 14th for the bigger, more powerful, clean groundswell sessions for the experienced crew.
Rusty.
