The Lowdown
Alright, Rusty here. Let’s have a look at what’s in store for us over the next couple of weeks.
Right off the bat, we’ve got a waiting game on our hands. The first real chance of a surf comes this Wednesday morning, September 9th, at Tramandai Pier (Platforma). It’s a small but glassy start with a 3ft south swell, period at 10 seconds, and the wind is dead calm. The water is sitting at 60°, which is a bit colder than we’d expect for this time of year. The combined energy is weak (319), so it’s not a powerhouse, but with conditions like that, you’ll have the place to yourself for a quiet paddle and some clean lines.
Don’t get too excited though, because the rest of the week looks pretty average. Thursday the 10th shows a bump in energy (530) but the swell is only 3ft and the wind is cross-onshore, making it messy. Friday is a write-off with rain and poor quality. The energy picks up again on Saturday the 12th with a 7ft SSE swell and a moderate cross-offshore wind in the morning, giving us clean conditions. The combined energy is strong (764), but this is getting into the range where it might be a handful for beginners. It’s a solid option if you’ve got the confidence.
The standout of the whole period, though, is Wednesday the 16th of September. The morning is looking magic: clear skies, a light WSW cross-offshore wind, and a 6ft south swell. The energy is pumping (706) and the conditions are clean. This is the one to mark on the calendar, folks. It’s not a monster, but it’s got push and the wind is right. Tramandai Pier should be offering some really good, rideable waves. The crowd situation is listed as “sometimes” busy, so expect a few others with the same idea.
After that, the following week gets a bit patchy. Friday the 18th has a clean morning with a 3ft south swell and a light offshore wind, but the energy is moderate (469). It’s a small but fun option if you’re keen. The rest of the second week is generally messy with onshore winds, a lot of east-northeasterly swell, and not much to write home about. The swell gets bigger again on the 21st and 22nd, but the wind is brutal, making it look more like a kite-surfing session than a clean paddle. The 24th of September has a small clean-up with 3ft and a strong cross-offshore wind, but it’s a light finish to a long run.
So, to sum it up: the first big chance is next Wednesday the 16th. That’s your best bet. Otherwise, there are a few scattered windows, but nothing else that’s going to get your heart racing.
Stay stoked, Rusty.
