The Lowdown
Alright, Rusty here again, breakin’ it down for Praia da Baleia in feet and Fahrenheit.
Right now it’s flat out sleepy. No real surf to speak of. We’ve got a tiny 2-3ft SE swell, period only 8 seconds, and a light cross-onshore breeze messin’ with the surface. Swell energy is weak at 177. Water temp’s about 70°, just a touch warmer than average for this time of year, so that’s a nice thing.
Monday afternoon stays poor, but Tuesday morning brings a shift. Offshore NNW wind at just 3 mph cleans things up. Still small, 2-3ft from the ESE, 8-second period – surfable, nothing to get too excited about. Tuesday afternoon turns glassy with a 1-2ft S swell, but that period jumps to 12 seconds. That’s a sweet groundswell window. Tiny but clean shape.
Wednesday and Thursday are ordinary: small S swells around 2ft, but winds stay clean and cross-offshore. Could snag a fun little wave if you’re keen.
Here’s the first standout: Saturday morning, August 1st. We get a punchy 6ft of E swell – period is short at 7 seconds, but the energy bumps to 588. The wind is dead calm, glassy. The size is getting into more intermediate territory, but for a beach and point like this, it should offer some fun, walled-up waves. Crowds can show up sometimes, so be ready for company.
After that, it drops back to small stuff through early August – clean mornings on Monday the 3rd and Tuesday the 4th, but only 2-3ft with short period. Nothing special.
Thursday afternoon, August 6th brings a good run: 3ft SSE swell, 11-second period, clean offshore NNW wind at 6 mph – solid combo, energy at 224 (moderate).
Now the big one: Tuesday afternoon, August 11th. This is the session to aim for. We get 5ft of S swell with a 13-second period – proper groundswell. Combined energy jumps to 747 – moderate to strong. Wind is glassy, just a slight air from the SE. This is the best of the whole forecast. The waves will have real power and shape. That 5ft size is best for experienced surfers; beginners will find it a handful. On a point setup like Praia da Baleia, the longer period will make for some nice, lined-up waves.
So, quiet start, but two clear winners. Saturday morning August 1st is the early call, and Tuesday August 11th afternoon is the one to really get stoked on.
Rusty.
