The Lowdown
Hey, Rusty here again. Let’s talk in feet and miles per hour for the same stretch of coast. We’ve got a bumpy few weeks ahead, but some windows to score.
The first real shot is Thursday, September 10th. The swell is 3ft from the SSE with a long 15-second period. The water temp is 62°, about 4° colder than usual, so expect a bit of a chill. The wind is glassy from the ENE. The combined wave energy is moderate at 556. This long-period groundswell at Guarda do Embau (Brazil) can be a bit fat for a river mouth, but the glassy surface makes it a clean, quiet paddle. It’s a worthwhile moment for the solitude.
Friday the 11th is a write-off in the morning with a tiny 2ft cross-off wind swell. The afternoon gets better with a 4ft NE windswell and glass, but it’s short-period (8 seconds) and weak.
Saturday the 12th is windy: 16 mph cross-shore winds and a 5ft choppy S swell. That’s more of a kite day.
Sunday the 13th and Monday the 14th are messy. Monday’s 7ft ENE windswell has a strong 1013 energy but a 7-second period and cross-onshore wind—another kite session.
Things clean up Thursday the 17th. Glassy 2 mph WNW winds, a 5ft SSE groundswell with an 11-second period. Strong energy at 607. This is the first big standout in the first week. The waves will have shape and power.
Saturday the 19th is also glassy, 7ft ENE swell with an 8-second period and strong energy (946). It’s big, so not for beginners (over 5ft), but the direction works well and the quality is prime. Expect a crowd.
Second week highlights: Wednesday the 23rd sees a 7ft S swell with a very long 11-second period, but cross-shore wind messes it up. The energy is very strong (1099), but the quality is lacking.
Thursday the 24th is the best bet for week two: glassy SSE winds, 6ft swell with a 12-second period, and very good conditions. The energy is strong (885). This is proper groundswell.
Friday the 25th also has glassy winds and a 4ft SSE swell with a 13-second period and strong energy (743). That’s a clean, long-period day worth waiting for.
Don’t rush the early days. Hang tight for the glassy windows on September 17th, 19th, 24th, and 25th. Those are the winners.
Rusty.
