The Lowdown
Alright, let’s break down what’s heading toward Tramandai Pier (Platforma) over the next couple weeks.
First thing – it’s gonna be a slow start. Most of the first week is small and average. Water temp is running about 60°, which is a touch colder than normal, so don’t skimp on the rubber.
Thursday, September 10th we’ve got a tiny 3-foot SSE swell, light cross-onshore breeze, and weak energy (503). Barely worth a look.
Friday 11th and Saturday 12th stay messy with onshore winds and lumpy conditions. Sunday the 13th is just as average. Honestly, the first week is mostly a washout.
Wednesday, September 16th – morning is the first real chance. Swell builds to a solid 7 feet from the south, period of 10 seconds, and energy hits 1060. Wind is light offshore from the west, glassy clean. That’s a proper session for experienced surfers – too big for beginners. The afternoon stays big but the wind swings onshore.
The next few days drop off again with strong north-easterly winds making a mess.
Saturday, September 19th morning is a nice little break – only 4 feet from the ENE, short period, but the wind is dead calm, glassy as glass. Perfect for a fun, easy paddle.
The real highlight is Wednesday, September 24th and Thursday, September 25th. Wednesday brings a long-period 14-second SSE groundswell at 6 feet, energy at 1551 – serious power. The wind is cross-onshore so a bit lumpy, but the push is real.
Then Friday, September 25th – this one’s a beast. Morning swell hits 10 feet from the east, energy 1595, and by afternoon it’s 13 feet from the ESE, energy 2933, with clean offshore wind from the WSW. That’s a monster – way too big for the pier, only for experts, and honestly looks more like a kite-surfing day than a paddle session. That long-period groundswell will unload heavy and straight at a beach setup like this.
So the call is: Wednesday 16th morning is your best true surf window for experienced crew. Friday 25th is huge but dangerous. Rest is small or blown out. The second week brings some serious size if you’ve got the nerve.
Rusty out.
