The Lowdown
Alright folks, Rusty here. Let's have a proper look at what Baleal Sul has got lined up for us.
Right off the bat, I gotta be straight with you – it’s a pretty grim start. For the first week or so, from Sunday the 9th right through to the morning of Monday the 17th of August, the conditions are just terrible. We’re talking onshore winds blowing straight into the beach from the NNW or NW, messing up any chance of a clean wave. The swell is a mix of short-period windswell with weak energy, and the wave comment says it all: "poor surf conditions" for every single session. The combined energy values stay low, mostly in the low 100s to low 300s for a while, showing there’s just no power or shape. You’re looking at a solid 8-day stretch of junk. It’s a tough spell, but that’s how it goes sometimes; forecasts can change, so don’t lose all hope.
Finally, things start to look up on the morning of Monday the 17th of August. The wind swings around to a light offshore from the SE at 6 mph, and the surf report says "expect good surf conditions." The swell is a solid 8 ft from the NNW, with a moderate period of 9 seconds, and the combined energy is a strong 885. That’s a powerful, clean wave on offer. Baleal Sul is a sheltered beginner spot, and with this size, it’ll be big and punchy – definitely not one for learners, as it’s well over the 5 ft mark. But for anyone with a bit of experience, the morning session is the standout. The water temp here is about 67°, which is normal for this time of year, nothing weird going on.
The morning of Tuesday the 18th of August is another good call. We’ve got a gentle offshore from the SSE at 9 mph, keeping the surface glassy. The swell drops a touch to 7 ft from the NNW, but the energy is still strong at 696. It’s clean, it’s powerful, and it’s a great follow-up session.
Wednesday the 19th and Thursday the 20th of August also start with clean, offshore conditions in the mornings, with the swell holding steady around 6 ft to 7 ft from the NNW. The energy stays high, in the 400 to 700 range. Each afternoon, the wind turns cross-off or onshore, so the early bird definitely catches the wave here.
Now, for the real standout of the whole outlook: Friday the 21st of August. The morning session is the absolute pick of the bunch. We’ve got a light cross-offshore breeze from the SW at just 6 mph, keeping the ocean clean. The swell is a solid 8 ft from the NNW, with a period of 9 seconds, and the combined energy is a massive 1131 – that’s very strong wave energy. The report says "expect very good surf conditions." This is a big, powerful swell with clean conditions. At 8 ft, it’s in the expert-only zone, but for the crew who can handle it, this is the session to circle on the calendar. It’s over a week away, so don’t hold me to it, but the potential is massive.
After that, the weekend of the 22nd and 23rd of August sees the onshores return and the swell drop off, turning things messy again. The following Monday the 24th of August is a marginal call with cross-onshore wind.
So to sum it up: suffer through the first week, then the morning windows from Monday the 17th through to Friday the 21st of August are your time. The absolute best bet is the morning of Friday the 21st – big, powerful, and clean.
Rusty.
