The Lowdown
Alright, Rusty here. Let’s be real: the next two weeks are a flat spell with a few flickers of life. The wave energy is low, and the wind is a constant headache. There’s one morning that might save the trip, but don’t expect any barrels.
From the end of July through the first week of August, it’s all knee-high slop. Swell heights are 0.3 to 0.9 feet, and the combined energy is mostly under 100 (30 to 110). The wind is cross or cross-on from the NNW or NW, which kills any chance of a clean face. The water temp is about where it should be for this time of year.
We get a pulse on the 9th of August. Sunday morning at Foz do Lizandro (river) is your best shot. We’ve got a 4 feet swell out of the Northwest, with a combined energy of 173 (moderate), and the wind is a light cross-offshore from the ENE. That’s clean. The waves are surfable, but the conditions are just ordinary. The swell period is a short 8 seconds, so it’s not going to have much push.
The next morning, Monday, the swell jumps to 5 feet from the NW, with a combined energy of 362 (moderate), and light cross winds from the NNW. That’s a serious size, but it’s a beach break with a 9-second period, so it’ll be a bit lumpy and tough to manage. The crowd factor is “sometimes,” so you might have some company. Only for the experienced folks.
After that, it’s dead. By the 11th, there’s zero swell, and the wind cranks from the NNW at 19-22 mph. That’s kite-surfing territory. The combined energy drops to single digits.
So, the long and short of it: if you’re itching, Sunday morning the 9th of August is your only real window. It’s not a classic, but it’s the cleanest we’ll see. The rest is a waiting game.
Rusty.
