The Lowdown
Alright, Rusty here. Let me break it down for you, what little we’ve got to work with. Honestly, this stretch is a tough one for Baleal Sul. You’re looking at a long run of nothing special. The first real chance for a surf doesn’t show up until Monday the 17th, and even then, it’s a pretty average setup.
The overall pattern is locked into a persistent NNW swell, but the wind is mostly onshore or cross-offshore, which kills the quality. The combined swell energy is moderate on most days (between 167 and 688), but the poor wind states keep the waves messy. The water is sitting at 67°F, a bit colder than average for this time of year, so you might want a thicker wetsuit.
The standout session in this whole 16-day window is Monday morning, the 17th of August. It’s the only time you get that magic word: glassy. The ENE breeze at 3 mph will have the surface like a mirror. The swell is a consistent 6ft from the NNW with a short 8-second period, so nothing too special in shape, but the clean conditions will make it the most rideable. The combined energy is a moderate 395. It’s not a world-class day, but it’s the best you’re going to get.
After that, it’s a bit of a write-off. Monday morning aside, most of the 17th afternoon and the whole rest of the forecast period is plagued with either onshore wind or cross-onshore breezes. The swell stays in the 2ft to 6ft range, but the quality is just poor. You get a bump in energy on the 31st (Monday morning) with 6ft and 503 combined energy, but the wind is cross-onshore, making for bumpy conditions. It’s a marginal call at best.
For beginners, be careful. The swell hangs around the 5ft to 6ft mark for most of the first week, which can be a bit much if you’re still finding your feet. The short period means it’s pretty weak, though. Expert surfers won’t find much to get excited about either, with nothing going over 8ft.
To be honest, it’s a blank run. No real standouts. Stick to Monday morning the 17th, get a dawny session in while it’s glassy, and then start checking the long-range charts again.
Rusty.
