The Lowdown

Hey folks, Rusty here. Let's get into this local stretch. I gotta be honest with you, it's looking like a tough slog for the next couple of weeks. We’re looking at a long dry patch before anything even starts to look surfable.

The big problem is the wind. For the next week, we’re dealing with a stubborn onshore or cross-shore flow out of the NW, N, and NE. It's just destroying the surface, turning any swell we get into a mess of chop and bumps. We'll see some decent sized pulses, like a 7ft WNW swell kicking off Tuesday afternoon, but it's blowing a strong 30 mph cross-wind. There's plenty of energy in the water, but you can't surf a washing machine.

We've got a solid week of mostly lousy conditions ahead. Thursday morning the 10th offers a little tease. We get a 3ft W-WNW swell with a lovely 10 mph offshore wind from the SW, making it clean as a whistle. But the swell is tiny, barely breaking. It's a knee-high ankle-slosher and not worth getting too excited about. And keep in mind, crowds are possible at Trestraou.

Friday the 11th shows a bit more size early, 5ft from the west, but the wind swings NW, cross-shore, and brings some chop. It's a marginal call at best.

This pattern holds through the weekend and into next week. We get a few more clean moments, like Sunday morning the 13th with a 6ft WNW swell and a 12 mph cross-offshore wind. The energy is there, but the wave quality is still rated poor—probably a bit lumpy. Honestly, with this much wind, the setup looks more interesting for kite surfing than paddle surfing for most of this period.

Then comes a massive gap. After that Sunday, it's just day after day of onshore junk or tiny dribble until we finally see a glimmer of hope way out on the horizon.

The only real standout, and I mean the *only* one, is way out there on September 23rd. A huge, very long-period WNW groundswell arrives. We're talking 4ft to 5ft swell with a period of 15 to 16 seconds. The raw energy is incredible. Now, here's the catch: long period groundswell like this can be tricky on a beach break, but at Trestraou, it might just work. The problem? It's forecast to be onshore wind again from the NE. But this is 16 days out—super promising, but very uncertain. If that wind drops, look out. This could be the best session of the month, but for now, it's just a dream on the forecast.

For those of you needing to get wet, the water temp is sitting a touch warmer than normal for the year, about 65°F.

So to sum it up: the next week is a write-off. Lots of wind, poor quality. The only potential bright spot is a distant, powerful groundswell at the very end of the run that might be worth waiting for if the stars align.

Stay patient, keep your boards waxed, and check back in.

Rusty.

Information about the Trestraou Surf forecast

The above surf forecast table for Trestraou provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trestraou can be found by selecting the local surf guide option on the grey menu. Our Trestraou 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 (Trestraou) 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 Trestraou 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.
