The Lowdown
Hey, Rusty here. Let’s talk surf for Tramandai. We’ve got a slow start, and then a whole lot of juice coming down the track.
Tramandai Pier (Platforma)
First couple of days? Just leave it. Weak, short-period slop and dodgy winds over the weekend. Save the wax. The first real chance to get wet is Monday, September 14th. We’re looking at a glassy morning with a light offshore wind from the WNW, switching to a glassy NE breeze in the afternoon. The swell is a modest 5ft from the south, but with that glass, it’ll be clean and fun for intermediate surfers. Water temp is 60°, which is about 3° colder than normal, so bring a thick wetsuit.
We get a few more clean, cross-off days at the start of the week, but the waves stay pretty small. The big news, the one you need to make a plan for, is Wednesday, September 23rd. The morning session is the absolute pick. Clear skies, a light SW breeze making it glassy and clean, and a solid 8ft south swell with an 11-second period. The energy is very strong. It’s going to be powerful groundswell. But – and it’s a big but – for a beach/pier, that size and power will be for experts only. The afternoon goes to 10ft and the call is it will be too big for this break.
Thursday the 24th is a write-off for paddle surfing. We’re talking 12ft of SSE groundswell with a 17-second period. That’s an absolute bomb, and with onshore winds, it’s strictly for the kite crew. Totally unsurfable for us.
Once that monster passes, it cleans up nicely. Saturday, September 26th is looking very tidy. Light cross-off breeze, a clean 4ft SSE swell with a 12-second period, and moderate energy. A really nice, clean day for a paddle without the terror of the mid-week swell.
There’s a few days of nothing at the beginning, so hang tight. Get out for the glassy fun on the 14th, but if you’re an experienced surfer looking for a challenge, the dawn patrol on the 23rd is the standout. Just know it’s a wild one.
Rusty.
