The Lowdown
Alright, Rusty here, looking at the same charts for the next couple of weeks. It’s a mixed bag, but there are a few good windows.
First real shot is Monday, September 7th. We’ve got a solid south swell at 5ft with a 10-second period and a combined energy of 504. The wind is light from the northwest, glassy. That’s a morning to wake up for. The water temp is about normal for this time of year. The afternoon goes onshore and messy.
Tuesday the 8th is smaller, 3ft from the SSE, 9-second period, 281 energy. The wind is cross-off from the north, so it’s clean but not big. Afternoon turns onshore.
Wednesday the 9th is glassy again with a 4ft south swell (11 seconds, 384 energy). Morning is clean. Afternoon is a washout.
We’ve got a gap for a few days. Thursday the 10th is marginal with a long 15-second period from the SSE, which can be a bit straight at the Pier. Friday the 11th is blown out. Saturday the 12th afternoon is huge: 10ft from the south, combined energy of 2034, but it’s too big for this break and the wind is cross-shore. That’s for experts only, if anyone.
The true standout is Monday the 14th of September afternoon. Swell at 8ft from the east, short 7-second period, but the wind is light and cross-off from the north. Combined energy of 841. The report says “expect very good surf conditions.” That’s the best session of the run.
Tuesday the 15th morning is also a winner: 5ft from the ESE with a moderate offshore wind from the west. Clean, 619 energy.
After that, the 17th and 18th are mostly blown out. The 18th has a 7ft south swell with a 14-second period, but the wind is terrible. That’s a kite day.
Saturday the 19th is a solid day all around. Morning has a 4ft south swell, 12-second period, light cross-off wind. Afternoon brings a 7ft ENE swell, short period, but with light cross-off wind again. Clean.
The 20th and 21st are marginal or blown out.
So, the best bet is Monday the 14th afternoon at Tramandai Pier (Platforma). That east swell with the light offshore wind is the one. Tuesday morning the 15th is also prime. The 19th is a good all-day option.
Watch out for the big stuff on the 12th, and I’ll see you in the water.
Rusty.
