The Lowdown
Alright, this is Rusty, and I’ve got the long-range outlook for Trestraou. Let’s be honest, the next ten days or so are a write-off. We’re looking at a real flat spell starting now, and the wave heights are tiny, often under 3ft, with a lot of cross-shore or onshore wind. The energy is just not there. The first half of the outlook is a total frustration – nothing but poor surf conditions and a lot of groveling. I can see a gap of nearly two weeks before we get a sniff of something real.
Then, finally, we get a moment of life. The morning of Saturday, August 8th, brings a bump. The swell picks up to 6ft from the WNW, with a combined energy of 442 (moderate). The wind is a light, clean cross-offshore breeze, so the lineup should be pretty clean. The water is a touch warmer than normal for this time of year, hovering around 66°. This is the standout of the window. It’s a solid, surfable size, but with that 6ft and a period of 9 seconds, it’s a good, punchy wave for the average to strong surfer. The downside is that swell is going to get a bit messy in the afternoon as the wind swings cross, so make the most of that morning session. After that, the swell hangs around in the 5ft to 5ft range for Sunday and Monday, but the wind is going to be cross or fresh and lumpy, so it won’t be as clean. The quality drops off hard after that. It’s a short-lived window of fun, but for Trestraou, that Saturday morning is the only real go.
Rusty.
