The Lowdown
Alright mate, Rusty here, and I’ve been staring at the charts for Trestrignel (Bretagne).
Right off the bat, I’ll be straight with you – this 16-day run is a tough one. The water is sitting at 67°F, which is a touch warmer than usual for this time of year, but that’s about the only thing that’s easy. The first real glimmer of hope doesn’t show up until Tuesday, the 8th of September, so we’ve got a gap of several days with nothing worth paddling out for.
Before that, from the 25th of August right through to the 7th of September, it’s a real battle. The wind is mostly cross, cross-off, or cross-on, and when it’s not, it’s onshore. The swell energy is mostly weak to moderate (between 32 and 921), but the biggest issue is that the conditions are just ordinary. The wind is either too strong or in the wrong direction, and the wave quality is poor. It’s a lot of chop and lumpy water. For a few days, like the 29th and 30th of August, there’s some decent size – 7ft to 6ft swell – but it’s coming with a fresh breeze and cross-off winds, making it messy. The period is short, around 8 seconds, so these are weak, wind-affected waves. Honestly, for a paddle surfer, this setup is a no-go. If you’ve got a kite, you might find some fun in that strong cross-shore wind, but for a surfboard, it’s a write-off.
Now, the highlight. It’s a long way off, but Tuesday morning, the 8th of September, is our best bet. We’ve got a 5ft swell from the WNW, with a period of 9 seconds. The combined energy is moderate (400). The wind will be light from the SW, giving us a clean, cross-off breeze. The guidance says the optimum swell direction is from the NW, so that WNW swell is a good fit. It’s not a huge day, but it’s the only time in the forecast where the conditions are genuinely good. Get your shortboard or a fish, and you’ll find some fun, clean waves. It’s a beginner-friendly size, and the crowds at Trestrignel are always a factor, so expect company.
After that, Wednesday the 9th of September sees a bump in size to 7ft, but the wind swings around to a fresh cross and cross-on, so it’s back to the lumpy stuff.
So, to sum it up: the only real standout is Tuesday morning, the 8th of September. Mark it in your calendar, but don’t hold your breath for the rest of the run.
Rusty.
