The Lowdown
Alright mate, Rusty here. Let’s break down what’s cooking at Foz do Lizandro for the next couple of weeks. Honestly, the first bit is a total washout. From Tuesday the 8th all the way through Saturday the 12th, it’s mostly flat or chopped-up slop. You’ve got a moderate to fresh cross-shore breeze blowing all week, and the swell energy is either zero or puny – values from 0 up to 123. The first real chance doesn’t show up until Sunday morning the 13th.
Sunday the 13th is the one to circle on the calendar. Early doors, the wind drops to glassy – that’s a massive plus. The swell is coming from the NW at 4 ft, with a period of 13 seconds, and the combined energy is 447. That’s moderate energy, but with those long-period lines, the waves will have proper shape and punch. Since this is a river break, the long period (over 11 seconds) works in its favor – expect sets to roll in clean and lined up. Glassy wind means it’ll be like surfing on a mirror. This is the standout session. The crowd factor is “sometimes,” so you might have company, but with conditions this clean, it’ll be worth it.
Monday morning the 14th is another glassy start – wind from the NNE at just 3 mph. Swell is 4 ft from the NW, period 12 seconds, energy around 378. Not as strong as Sunday, but still clean and fun before the wind switches onshore that afternoon. That Sunday through Monday morning stretch is the real sweet spot.
After that, things go south again. Tuesday the 15th through Thursday the 17th, it’s moderate to fresh cross-shore winds with tiny, weak swell – 2 ft to 3 ft. Not worth paddling out for.
Looking further ahead, Saturday the 19th morning shows some promise. Light offshore breeze from the SSE at 6 mph, clear skies. The swell is 4 ft from the NW, period 10 seconds, with a combined energy of 273. It’s clean and surfable, but the shorter period means the waves won’t have the same grunt as the 13-second sets from earlier in the week.
By Monday the 21st, we start to see some serious energy building – but it comes with heavy wind. Late afternoon on the 21st, you’ve got 5 ft NW swell, period 17 seconds (very long period), but the wind is a fresh 22 mph cross-shore, making it lumpy. The energy is strong at 1288, but the conditions are marginal at best.
Then Tuesday the 22nd gets nasty – near gale-force cross-shore winds at 31 mph, with 7 ft NW swell. That’s expert-only territory, and honestly, it looks more like a kite-surfing setup than paddle surfing. The combined energy hits 1744, which is strong, but it’s going to be a messy, blown-out ocean.
By Wednesday the 23rd, the wind drops back to a moderate cross-off breeze, and the swell settles to 5 ft from the NW, period 12 seconds, energy 574. It’s cleaner, but the forecast is still marginal due to tide or conditions.
So to wrap it up: if you can only pick one session, make it Sunday morning the 13th – glassy, long-period NW groundswell, clean waves. Monday morning the 14th is the backup. After that, it’s a waiting game for cleaner windows later in the second week, but those are less certain. Keep an eye on it.
Rusty.
