The Lowdown
Hey folks, Rusty here, and for this stretch of coast, we’re stuck in a bit of a lull, but it won't last forever. There’s a long run of small, messy days ahead, but one session at the very end has a bit of a pulse.
It kicks off on Tuesday the 18th of August with a tiny NW swell at 2 feet and a short 8-second period, barely worth a look. The wind is blown out onshore or cross-on, and the combined wave energy is only 98, so it’s flat out there. Wednesday and Thursday are even worse – just 0.7 to 2 feet of weak slop. No reason to paddle out.
Friday the 21st sees a bit more life, with the NW swell building to 4 feet in the morning and then 5 feet by the afternoon. The combined energy jumps to 211 in the morning and a solid 415 by the afternoon – a moderate to strong push of energy for sure. But the wind is a killer: fresh cross-shore all day, turning the ocean into a lumpy, cross-chop mess. The break is a beginner spot, and with that messy wind and a period stuck at 7 to 10 seconds, it won't be clean for anyone.
Saturday the 22nd is more of the same – lumpy cross-shore, moderate energy in the mid-300s, but still messy. Sunday the 23rd sees the swell hit 5 feet in the morning and 5 feet in the afternoon. That’s some size, but it’s paired with a lousy 8-second period and fresh cross-shore winds. The waves will be steep, bumpy, and a chore to surf. That drags into Monday the 24th and Tuesday the 25th with the swell dropping back to about 3 feet, still sloppy.
The next Wednesday the 26th offers a clean window, but with the swell barely at 1 foot, it’s essentially flat. Thursday the 27th and Friday the 28th show some cleaner conditions with light cross-offshore winds in the mornings, but the swell is a weak 4 feet from the NW with a very short 7-second period (combined energy around 111-115). It's clean, but there’s no power behind it.
Then, we get the only real highlight. Monday the 31st of August, the morning session shows a 5 foot NW groundswell with a reasonable 9-second period and combined energy of 353, which is solid. The wind is only a light breeze, cross-on, so there might be some rideable lines if you can find a sandbank. It’s still only a 1/10 on the day, but after this long dry run, it’s the best we’ve got. The afternoon on the same day is already looking blown out again.
Into the second week, there's nothing to get excited about. Tuesday the 1st and Wednesday the 2nd of September look like small, onshore slop.
So, if I’m picking the one standout here, it’s that Monday morning the 31st of August at Fonte da Telha. The NW swell direction isn’t perfect for this beach break, but with that moderate energy and a light wind, it’s your best chance. It’ll be a bit fat on the sand, but for a beginner-friendly spot, you might snag a couple. Expect a crowd – this place is often packed when there’s any size.
Keep your hopes up, but don't expect much for a while.
Rusty.
