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.

Information about the Trestrignel Surf forecast

The above surf forecast table for Trestrignel provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trestrignel can be found by selecting the local surf guide option on the grey menu. Our Trestrignel surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Trestrignel) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Trestrignel may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
