The Lowdown
Alright folks, Rusty here. Let’s get straight into it. Honestly, looking at the next 16 days for Foz do Lizandro… it’s a tough one. We’ve got a long stretch of nothing worth paddling out for. The whole first week and a half is basically a write-off. From the 18th of July right through to the 28th, it’s just poor surf conditions – cross-onshore wind, chop, and tiny, weak swell. You’re looking at combined energy readings mostly under 100 (weak stuff), with swell heights barely scraping 3ft and often much smaller, with short periods. Not a single good score in that whole run. The ocean is just not playing ball.
Then, we finally get a glimmer. On the 29th of July, Wednesday morning, things start to shift. The wind drops right back to a light 3 mph from the north, making it a light cross-shore with some crossing ripples. The swell bumps up to 4ft from the NW with a period of 10 seconds. The combined energy jumps to 285 (moderate wave energy). It’s only a “marginal surf forecast or questionable tide conditions” but it’s the best we’ve seen. The afternoon holds similar energy at 256.
The water temperature is sitting at 68° with an anomaly of 0.7°, so that’s pretty much bang on average for the time of year.
After that little blip, it dies again. The 30th and 31st of July, and the 1st and 2nd of August, are all flat with zero combined energy. Some mornings have clean offshore winds from the east-northeast, but with no swell, it’s just a glassy lake.
So, the standout here is the 29th of July, Wednesday. It’s the only chance in the whole window. The NW swell at 4ft is small, but that 10-second period will give it some shape. The wind is light, which is a big positive. It’s a river break, so it can handle a bit of a longer period. But don’t expect a classic session – it’s marginal. If you’re a beginner, 4ft is fine. If you’re desperate, you’ll take it. For the rest of the time, we’re waiting for a proper pulse.
Rusty.
