The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for Trestraou.
Alright, mate, I've got to be straight with you – the next couple of weeks are looking pretty grim for a proper paddle. The forecast is a long stretch of tiny, weak swell and onshore or cross-onshore winds that are going to chop things up. The first recommendation for a surf doesn't even pop up until Wednesday the 26th of August, so we've got a big gap of nothing from now until then. That's a solid week of poor conditions.
The one standout, and really the only window worth getting excited about, is Wednesday morning, the 26th of August. We'll see a clean, waist-to-chest high swell, around 5 ft, rolling in from the WNW with a moderate-energy period (combined energy of 460). The wind is looking light and offshore from the WSW, which is a major plus, meaning the waves should be clean and well-shaped. This is a big window of opportunity after a long flat spell, so if you can, get out there. The water temperature is about average for this time of year, so no major surprises there.
After that, the rest of the outlook is a write-off. Thursday and Friday see the wind pick up and the conditions deteriorate back into choppy, messy surf. The very end of the forecast, around the 30th of August, shows a bigger pulse of 5 ft to 8 ft swell, but it's coming in with a poor onshore wind and short period, making it all look like a washing machine. At that size, with those winds, it's more of a kitesurfing setup than a clean surf session.
So, keep your eyes on Wednesday the 26th. That's the only real chance for a decent wave in the next two weeks.
Rusty.
