The Lowdown
Alright folks, Rusty here. Let’s be straight with you: if you’re scoping Trestraou for the next couple weeks, the surf outlook is a real bummer. The whole 16-day stretch is a tough go, and there’s not a single standout session where everything comes together. You’ll see pulses of swell roll through, but the wind is almost always a problem, leaving the ocean looking messy and bumpy.
The water’s sitting around 65°, which is pretty much normal for this time of year, so at least you won't be shivering while you're getting skunked.
We kick off on Thursday, September 3rd, with some knee-to-waist high swell (5ft) from the west, but a moderate cross-offshore breeze out of the southwest gums it up. Wave energy is moderate, but it’s nothing special. Friday the 4th sees the swell bump up to chest-high (6ft), but it’s still blown out by cross-shore winds.
Saturday the 5th is probably the biggest letdown of the run. We’ve got a proper groundswell rolling in from the WNW with a long 12-second period, pushing decent waves (5ft) and a good punch of energy. But the wind is onshore from the northeast, wrecking the surface. It’s a real teaser.
The following week is a write-off. You get a bigger pulse on Monday the 7th (7-7ft, 12-second period) with strong energy, but the cross-shore winds are up to 15 mph. Tuesday the 8th sees the swell hit a peak of 10ft, but again the cross-shore wind is howling. That’s big, powerful, and totally chopped up. It’s too big for beginners and just ugly for everyone else. For the rest of the week and into the next, the wind stays onshore or cross-shore, and the swell fades.
Even the offshore winds we get on Thursday the 10th can’t save us, because the swell drops to a pathetic 2-2ft. There’s simply no push.
The second week is a total snooze. The surf stays small and messy, with a weak, short-period NNE swell mid-week that barely registers. By Friday the 18th, it’s practically flat.
Honestly, this is a total dry spell for surf. It’s a sheltered spot that needs the right combo, and for 16 days, it just doesn’t happen. The setup looks way more interesting for kite surfing than paddle surfing on most afternoons. For the rest of us, it’s a good time to wax the board for a flat paddle or hope the forecasts change.
Rusty.
