The Lowdown

Alright folks, Rusty here. Let’s have a proper look at what’s on the menu for Foz do Lizandro over the next couple of weeks.

Right now, we’ve got a bit of a flat spell to get through. Thursday the 10th and Friday the 11th are pretty much a write-off with tiny, weak swells and a stiff cross-breeze making a mess of things. You’re looking at ankle-snappers at best, and the conditions are just poor. Hang loose, it won't last forever.

We start to see a flicker of life on Saturday the 12th morning. A small 2ft swell from the WNW with a 10-second period rolls in, and the wind goes light cross-offshore. The combined energy is still pretty weak at 70, but at least it’s clean. Saturday afternoon gets a bit lumpy again, so make the most of the morning if you’re desperate for a paddle.

The real standout of the first week is Sunday the 13th morning. The swell pushes up to 3ft from the NW, but the real magic is the period jumping to 13 seconds. That’s a proper little groundswell, and with a slight offshore breeze from the SSE, it’s going to be glassy clean. The combined energy climbs to a solid 330. This river mouth setup will be working nicely. Just be aware, it can get a bit of a crowd here sometimes, but for waves *that* clean, it’s worth sharing. The water temp is sitting about average for this time of year, so a 3/2 wetsuit will be fine.

Sunday afternoon gets a bit bigger at 4ft from the NW, but the wind swings onshore, making it a bit questionable. Monday the 14th holds some similar 4ft groundswell, but the cross-onshore wind spoils the party a little.

We then hit a long, poor stretch of lumpy cross-shore junk from Tuesday the 15th right through the middle of the following week. It’s not worth your time.

Now, for the one to circle on your calendar: Monday the 21st September morning. This is the big one for experts only. We’re looking at a 7ft swell from the NW with a 14-second period. That’s very long-period groundswell. The wind is light cross-offshore, and the combined energy is absolutely pumping at 1710. This is legitimate, solid, powerful swell. However, that size at a river break like Foz do Lizandro is going to be cranking and will be well over the head. It’s strictly for experienced surfers who know the rip and the bar. For the rest of us, it’s a spectator sport.

After that, the surf settles back to smaller, cleaner 3ft waves on Tuesday the 22nd, but the onshore wind creeps back in.

Right at the tail end, Thursday the 24th and Friday the 25th September show some very promising signs. Thursday morning sees a 4ft swell from the NW with a very long 17-second period, combined energy of 1072. Friday morning holds 6ft from the NW with a 13-second period and 1205 energy. These are big, long-range groundswells. The caveat is the cross-shore wind, which will put a bit of texture on the face. It’s a long way out, so treat it as a promising prospect rather than a done deal. Could be epic, could be a windswell mess. We’ll see.

So, the pick of the fortnight is Sunday the 13th morning for clean, fun waves, and Monday the 21st morning for the big, expert-only session. Keep your eyes on the 24th and 25th for a potential late score.
