The Lowdown
Alright folks, Rusty here. Let's have a look at the local outlook for Trestraou. It's gonna be a bit of a slow burner this time, but there's a couple of windows that could be worth your time.
Right now, it's flat with a messy cross-onshore breeze, so don't even bother. We've got a few days of small, cleanish surf coming in from Tuesday the 25th. The wind will be light offshore or cross-off, which is a big plus for the surface, but the swell is tiny – we're talking knee-to-waist high at best. The energy is on the low side. It's nice for a longboard or a beginner's session, but nothing to write home about.
The first real standout arrives on the morning of Saturday the 29th of August. We've got a solid pulse of swell, with a wave height of about 8 feet. That's a bigger, powerful, west-northwest swell. The wind is clean cross-off. This is definitely one for experienced surfers only, as it's getting a bit hefty. The period is a short 8 seconds, so expect it to be a bit lumpy and on the faster side.
The surf drops off after that, but keep an eye on the forecast for the start of September. The morning of Sunday the 6th of September is promising, with another 8-foot swell from the west-northwest, and the energy is through the roof. The wind is a moderate cross-shore, so it won't be glassy. This is another big, powerful swell, definitely expert territory, and the period is still short at 9 seconds.
The biggest potential for the whole forecast is on the morning of the 8th of September. We're looking at a 10-foot swell with a very long period of 15 seconds. That's a serious amount of water moving. This is a groundswell, mainly for the experts. The wind is a moderate cross-shore, so it won't be perfect, but the sheer size and power will be incredible. Remember, long-period swell like this can be a bit tricky on a beach break, but Trestraou is a beach-and-reef setup, so it might offer some standout peaks. This one is still over a week away, so keep your fingers crossed.
The water temp is about average for the time of year, nothing unusual.
