The Lowdown
Alright folks, it’s Rusty here, and I’ve been staring at the charts for our local stretch. Honestly, it’s a bit of a mixed bag and we’ve got some waiting to do. The first week is pretty grim, but if you’re patient, there’s a couple of windows that could pay off.
Right now, we’re looking at a long dry spell. There’s basically nothing worth paddling out for from now until the morning of Friday the 12th. The water temp is sitting at 62°, which is pretty much bang on average for this time of year, so no shocks there.
The first real standout, and I mean the only real standout in the first week, is the Saturday morning session on the 12th at Tramandai Pier (Platforma). We’ve got a solid 10ft swell from the SSE, and the wind is set to be light and offshore from the SW. That’s a clean, lined-up combo. The combined energy is absolutely pumping at (1517), so there’s serious power behind it. But – and this is a big but – 10ft is well into expert territory. This is not for the faint-hearted or the beginner crew. The swell period is 10 seconds, which is a solid medium period, so it’ll have some push. Saturday morning is the pick, no question.
The rest of the 12th gets messy, with the wind swinging round on the afternoon. Then from Sunday the 13th through to the 15th, it’s a write-off. We’ve got rain, onshore winds, and choppy, junky waves. Honestly, the setup on the 13th with 7ft and 12 mph onshore winds looks more interesting for the kite surfers than us paddle guys.
We get a little flare-up a bit later. The morning of Wednesday the 17th looks clean again with a light offshore wind but only a small 5ft SSE swell. It’s rideable, but nothing to write home about.
Now, if you can hold out, the real gem of the whole forecast is the afternoon of Friday the 18th. The wind is forecast to go dead glassy, with a light southerly breeze, and we’ll have a clean 3ft swell from the S with a period of 11 seconds. That’s a long period groundswell, and at Tramandai Pier, that’s going to produce some long, peeling lines. The energy is moderate (369), but with glassy conditions, the quality will be top-notch. That’s the session to circle on the calendar.
The morning of Saturday the 19th also looks clean with a light offshore, but the swell is a shorter period 5ft from the ENE, so it won’t have the same shape as the day before.
After that, it trails off again. The morning of the 23rd has a glassy 2ft south swell, but the energy is weak (134). It’s surfable, but very ordinary.
So, to wrap it up: the big Saturday (12th) is for experts only, but the Friday the 18th glass-off is the one for everyone else. Keep your eyes on that.
Rusty.
