The Lowdown
Alright, Rusty here again, but this time in feet and miles per hour. Let’s break down Praia do Rock.
This is a beginner-friendly sandbar, and it needs the right wind from the ENE to clean it up. There’s a bit of a slow start before we see anything worth paddling for.
Tuesday morning, August 11, is a no-go. There’s a tiny 3ft NW swell with a super short period of 5 seconds. Wave energy is weak (85). Water temp is 69°, which is a touch warmer than usual for this time of year. The wind is glassy from the WNW, so the surface is clean, but the waves have no juice. By afternoon, the wind swings NW and hits 25 mph, turning the place into a cross-shore mess.
Wednesday morning, August 12, is the first real highlight. A 3ft W swell with a 10-second period and moderate energy (200). The wind is glassy at 5 mph from the W. This gives you clean, fun little waves – perfect for a beginner. It’s the best thing going in the first week. The afternoon gets onshore and choppy again.
Thursday the 13th and Friday the 14th are both marginal. Waist-high swell but cross-onshore winds and a bumpy surface. Not worth it.
Saturday morning, August 15, brings a much bigger 7ft NNW swell with strong energy (666). That’s too big for this spot. The wind is light and cross-shore, but it’s expert-only territory. By afternoon a 35 mph NW wind blows it all to pieces. This setup looks more interesting for kite surfing than paddle surfing.
Sunday morning, August 16, is your best bet. The swell is a solid 5ft from the NNW with 8-second periods and moderate energy (319). The wind is glassy from the NNE at 5 mph. That’s clean, fun surf for anyone comfortable in that size. This is the standout session of the whole 16 days.
Monday the 17th and Tuesday the 18th bring 5ft to 5ft NNW swell, moderate energy, and clean cross-off winds. Surfable but not a standout.
The second week gets smaller. From Wednesday the 19th to Friday the 21st, the swell drops to 2ft to 3ft, mostly weak to moderate energy (94-131). Clean mornings with small waves, but nothing with any punch. The afternoons are a no-go with strong winds.
The weekend of the 22nd and 23rd of August sees a 3ft to 5ft NW swell with longer 10 to 11-second periods. The energy gets strong (401) on Saturday morning, but the cross-shore wind ruins it.
The final days, the 24th to the 26th of August, have a 4ft to 5ft NNW swell, with strong energy (up to 748 on the 26th morning). The morning of the 26th has clean, cross-off winds, making it a promising long-range option, though it’s far out and less certain.
To sum it up: go for Wednesday morning, August 12 for small clean waves, or the real standout is Sunday morning, August 16 for a proper session. The rest is a mix of flat spells and blown-out days.
Rusty.
