The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of surf on the cards at Molhes de Mampituba, no real quiet start here. The first few days are looking strong, with a mix of clean conditions and decent energy. The water temp is about average for this time of year, nothing out of the ordinary.
Friday morning kicks off with a 6ft swell from the ENE, period at 8 seconds, and a cross-off wind from the NNE. The energy is moderate (798), and the waves are clean. It’s a good start, but the afternoon turns messy with a cross shore wind, so get on it early.
Saturday is the standout of the first week. The morning brings a 7ft swell from the ENE, period 9 seconds, and a clean cross-off wind. The energy jumps up to 1075 (moderate-strong). This is for experienced surfers only – it’s solid, powerful, and clean. The afternoon holds up too, with 6ft and still cross-off, though the energy drops a bit to 873.
Sunday morning holds at 7ft from the NE, but the forecast is a bit marginal. The afternoon though, gets a light cross-off from the NNW with 6ft ENE swell (8 seconds) and clean waves. Energy is 709.
We get a bit of a breather Monday with a smaller 4ft swell from the ENE, but the morning is glassy – dead calm wind from the west, energy at 255 (weak). That’s a nice, clean, small day for a longboard.
Tuesday morning is still clean with 4ft, but the afternoon gets blown out. Wednesday morning though, is another glassy gem – 4ft from the SSE, zero wind, energy at 500 (moderate). That’s worth a look for a peaceful session.
After that, the surf hangs around but the quality drops. Saturday 25th July afternoon is a nice surprise – glassy conditions again, with a 6ft swell from the ENE, but a short period of 7 seconds. Energy is 752 (moderate). It’s clean, but a bit short-period.
The following Monday 27th July morning has a clean 7ft ENE swell, period 8 seconds, energy at 935 (moderate). That’s a good one for experienced surfers again.
The tail end of the run gets serious but messy. From 29th July we see a big south swell building, but the wind is onshore and choppy. We’re looking at 10ft from the south with a long 12-second period, but the energy is massive (3878 – very strong) and the conditions are poor. 31st July has a 8ft SE swell, period 14 seconds, energy at 2523 (very strong), but again cross-shore wind and marginal quality. This is more of a kite-surfing setup than a paddle session.
Overall best bet: Saturday 18th July morning. The 7ft ENE swell, clean cross-off wind, and moderate-strong energy make it the pick of the pack for experienced surfers. Friday 17th July morning is a close second for a cleaner, slightly smaller wave.
Rusty.
