The Lowdown
Alright, rusty, let’s get into it. The only game in town for the next 16 days is Praia da Baleia. It’s a beach and point break that’s exposed to the south swell, and it’s a beginner-friendly spot that’s fairly consistent. The water temp is about average for this time of year, nothing to write home about.
First up, we’ve got a slow start. Saturday the 5th is tiny, with 1ft of weak SSE swell, only 10 seconds between waves, and the combined energy is a weak 113. It’s glassy but the waves are just ordinary. Not worth paddling out for.
Sunday the 6th gets a bit bigger, but it’s a mess. Southerly swell at 6ft, short period of 7 seconds, and a cross-on wind. Combined energy hits 437, but the conditions are poor. It’s a write-off.
Now, Monday the 7th is where it starts to get interesting. The wind drops to glassy, and we get a 7ft south swell with a 10-second period. The energy is a solid 906. The morning looks clean and very good. This is a standout for the first week—clean, decent size, and the point setup should handle that long period nicely. It’s a good one for experienced beginners, but it’s not too big for the learner crowd. Crowds are sometimes an issue, so keep an eye out.
The good run continues into Tuesday the 8th. Another glassy morning, 6ft swell from the ESE, period of 7 seconds, and energy at 561. It’s a bit shorter period, but the conditions are still very good. Wednesday the 9th is a bit smaller, 4ft, but still glassy and good. Thursday the 10th drops to 3ft, but the period stretches to 11 seconds, giving it a nice groundswell feel. Still glassy in the morning, but the afternoon gets a light cross-on.
The middle of the month gets a bit messy. From the 12th to the 13th, we see a mix of cross-off winds and a building swell. The 13th brings a 8ft south swell with 11 seconds, but it’s cross-onshore, so the quality is marginal. That’s big enough to be expert-only territory.
Now, the real standout of the entire outlook is from the 14th to the 15th. Monday the 14th is glassy all day, with a 7ft to 8ft SSE swell, period of 11 to 12 seconds, and energy over 1200. This is excellent for experienced surfers. Tuesday the 15th is even better: a 8ft SSE groundswell, period of 14 seconds, and a massive energy of 2571. It’s glassy in the morning. This is a powerful, long-period swell. On a beach and point break like this, it’ll be lining up nicely, but it’s pushing into expert-only size. If you’ve got the skills, that Tuesday morning is the best on offer.
The energy stays high through the 16th, with a 6ft SE swell, 14-second period, but a cross-shore wind picks up. The 17th and 18th drop back to 5ft and 4ft, with cleaner conditions. The 19th brings a 4ft south swell, glassy in the morning. Finally, the 20th wraps it up with a 6ft east swell, 7-second period, glassy conditions, and energy of 511.
Overall, there’s a few days of flatness at the start, but from the 7th onward, there’s almost always something to ride. The standout is definitely the 14th and 15th, with that big, clean, long-period groundswell. If you’re an experienced surfer, don’t miss that Tuesday morning.
Rusty.
