The Lowdown
Right then, let’s have a look at what’s on offer for Trestraou. Straight up, I gotta be honest with you – it’s a bit of a tough stretch. The whole 16-day window is looking pretty grim. There’s a solid run of tiny, weak, and messy swell with cross to onshore winds that’s gonna leave us scratching our heads. We’re looking at a good week or more of barely ankle-biters before anything even starts to get our attention.
The first real pulse of size that shows up is around Tuesday the 18th of August. We’ve got a jump in energy, with the combined swell energy hitting 370 on Tuesday morning and climbing to 541 in the afternoon. Swell is coming from the WNW at 7ft, but with a period of 8 seconds, it’s a short-period wind swell, not a clean groundswell. The wind is a cross-offshore from the west, which is about as good as it gets around here, so the surf will be clean. However, at 7ft, this is really only for the experienced crew. Beginners should sit this one out. That’s your best bet in the whole window, but it’s a bit of a one-trick pony.
Keep an eye on the morning of Saturday the 22nd of August too. We see another lift in swell, with 5ft from the WNW and a combined energy of 372. The wind is onshore from the north, so it’s not going to be perfect, but it’s a glimmer of hope. The water temperature is sitting at 65°, which is about 1° warmer than average for this time of year, so it’s not a big deal, just a touch on the nice side.
Apart from that Tuesday and maybe that Saturday, honestly, it’s a lot of waiting. The setup is a sheltered spot, so it needs a decent push from the west-northwest to get any juice. Most of the time, the swell is just too small and the wind is working against us. It’s a real bummer, but sometimes that’s the way it goes. If you’re desperate, you might find a knee-high ripple on the 18th, but don’t hold your breath.
Stay patient, and keep your eyes on the charts. This is Rusty, signing off.
