The Lowdown
Right then, let's have a look at what's on the cards for Tramandai Pier (Platforma). Bit of a mixed bag, but we’ll get through it.
Honestly, for the next week and a bit, there’s not a whole lot to get excited about. The first recommendation doesn't come until Thursday the 10th of September, but even then it’s pretty ordinary. The swell is small, only 3ft from the SSE with a 15-second period – that’s a proper groundswell, but the cross-on wind from the ENE makes it messy. The wave energy is moderate (503), so there’s some push, but it’s not clean. The water temp’s about average for this time of year, nothing unusual.
Friday the 11th is a weird one. The morning is a write-off with rain and choppy conditions from a 12 mph cross-on breeze. But Friday afternoon? Glassy as a mirror – no wind at all. The swell drops to 3ft and the period shortens right down to 7 seconds. It’s surfable, but that short period means it’ll be fat and weak. A real flash in the pan.
The first real standout is a week away. Tuesday the 15th of September, the morning session is where it’s at. A clean 5ft swell from the ENE, period a touch longer at 9 seconds, and a solid offshore wind from the west. The wave energy is strong at 620, and with that offshore breeze, it’ll be clean and lined up. This is the pick of the first week if you can wait.
But the absolute best of this entire outlook is Wednesday the 16th of September. Get up early. The morning is showing a clean 8ft swell from the SSE, with a very long 11-second period. The wave energy is pumping at 1221 – that’s proper power. The wind is light offshore from the west, just a slight air. This is going to be excellent, but listen, that size is pushing 8ft, so it’s for experienced surfers only. Too big for beginners. It’ll be a bit of a wait for the sets with that period, but the shape will make it worth it.
After that, the surf drops off again. There’s a small window on Friday the 18th morning with a clean 6ft wave from the ENE and a cross-off wind, but it gets messy in the arvo. Another interesting one pops up right at the tail end. Thursday the 24th of September, the afternoon session could be special. The swell jumps to 8ft from the east with a short 7-second period, but it’s glassy – no wind. That’s a lot of raw, weak, lumpy water moving around, but glassy is glassy. For an expert, that’s a session with some heavy, fat lumps.
Other than these couple of windows, there are gaps of three or four days in a row where I wouldn't even bother paddling out. The winds are mostly onshore or cross-onshore, ruining what little swell there is. Keep your eye on Wednesday the 16th – that’s the one.
