The Lowdown
Right, folks, Rusty here. Let’s have a look at what we’ve got coming down the line. Gotta be straight with you – for the next week or so, it’s a bit of a rough patch. We’re looking at onshore winds and messy conditions more often than not, so you’ll need to pick your moments. The real standout, the one you want to circle on the calendar, is a Tuesday morning about a week out. That’s the one that looks worth getting excited about.
Kicking things off now, and through to the 17th of August, it’s a write-off for decent waves. Winds are howling onshore, and the surf, when there is any, is getting chopped up. It’s a stretch of over a week with no real recommendations. The swell energy is there, climbing from a weak 116 to a moderate 533 by the 17th, but it’s all blown out.
Then we get our moment. Tuesday the 18th of August, first light. Baleal Sul. The stars line up: the wind flips to a light easterly, coming straight off the land at just 6 mph. That’s cross-offshore and it’ll put a clean, smooth face on the waves. We’ve got a solid 8 ft swell coming from the NNW with a period of 9 seconds, packing a powerful punch – the combined energy is a strong 1030. This is proper groundswell energy. It’s a sheltered spot, and the optimum direction is from the W, so we’re not bang on the money for pure shape, but the clean wind and the size will make up for it. This one’s for the experienced crew – 8 ft is expert territory. It’s an inconsistent break, but when it’s this clean and this size, it’s a proper treat.
After that, we go back into the spin cycle. The 19th and 20th of August show a glimmer, with a glassy morning on the 20th and 6 ft swell, but it’s short-period, mushy energy, and by the afternoon the onshores are back. Then from the 21st through the 23rd, it’s another stretch of strong onshore winds and lumpy, choppy conditions with swell sizes building back up near 8 ft. Not ideal for a paddle.
The 24th looks a little more marginal – a light cross-onshore with 7 ft swell, but the conditions are that "questionable tide" kind of vibe. By the 25th and 26th, we’re tapering off. The 26th of August has a 3 ft small swell, but again a cross-onshore breeze.
So there you have it. A long wait for a single, stellar morning. If you can make it to Baleal Sul on the morning of Tuesday the 18th of August, you might just score the session of the forecast. Be ready for it.
Rusty.
