The Lowdown
Alright, Rusty here. Let's look at what's going down at Tramandai Pier. This 16-day outlook is a bit of a slow burn. The first week is mostly a dud with the wind working against us, so we're looking at a long stretch of nothing special before the ocean wakes up.
The first real chance is Monday, September 7th, in the morning. The water is 62°, which is dead average for this time of year. The waves are 6ft from the south, with a 10-second period and a moderate energy reading of 566. The wind is light from the WNW and offshore, so Tramandai Pier (Platforma) will be clean and fun. The south swell direction is working well here. This is the highlight of the first week, but keep in mind the break is inconsistent, so you'll be waiting for the sets. The afternoon is a no-go because the wind swings east and messes everything up.
From Monday afternoon all the way through to the following Sunday, it's a real battle. The wind shifts onshore, the swell drops, or it gets way too big. On Saturday the 12th, the swell jumps to 13ft with a massive energy reading of 7183, but the data says it's too big for the break. The wind is cross-off and clean, but that's a lot of water for only the most experienced surfers. Sunday the 13th is also oversized at 10ft with 3012 energy, but the wind is onshore and ugly. It's a week of either too messy or too heavy.
The next real window is on the 20th of September, a Sunday morning. We get a 12ft swell from the ENE, but with a short 9-second period. The energy is strong at 1983. The wind is light from the west, giving us clean, cross-off conditions. The data flags it as too big for the break, but if you're a proper charger, the early morning glass could be a wild ride. Monday the 21st is similar at 10ft from the ENE, but the wind is onshore again.
So, the only true standout is that Monday morning, the 7th. It's a clean, offshore, head-high session with a south swell that's perfect for the spot. The rest of the forecast is a test of patience, with either small waves, bad wind, or just too much power. Get out on the 7th if you can.
Rusty.
