The Lowdown
Alright, this is Rusty. Let’s see what we’ve got down at Tramandai Pier (Platforma).
Monday morning is looking rough. There’s some swell at 2.4m, but it’s messy and cross-shore – not worth the paddle. The energy is moderate (890), but the wind is just trash for a clean session.
Tuesday morning finally shows some promise. The swell drops to 1.6m and the wind swings offshore from the SW – clean lines and better shape. It’s a small window, but it’s the first real chance for a surf. Energy is moderate (348).
Wednesday and Thursday are mostly a washout. Light onshore breezes and rain will keep the surf small and choppy.
Now, here’s where it gets good. The real standout is Sunday the 23rd through Monday the 24th. Sunday morning brings a clean 2.1m S swell with a long 11-second period and offshore W winds. Energy is strong (1030). This is a groundswell, and it’s going to be powerful and clean. Monday the 24th morning is even bigger: 2.4m from the south with a 12-second period and offshore W winds. Energy is very strong (1602). This is the best of the whole run – big, clean, and punchy. It’s too big for beginners, but for experienced surfers, this is the session to aim for.
After that, the wind turns onshore from the ENE on Tuesday the 25th, and the surf goes downhill. Choppy and lumpy. There are a few cleaner windows on the 28th and 31st, but nothing matches that Sunday-Monday power.
Water temp is about average for this time of year.
In short: skip the first week. The big action is on Sunday the 23rd and Monday the 24th of August. That’s the one to circle. The end of the month has a glassy morning on the 31st, but the best is all in that late August weekend.
Rusty.
