The Lowdown
Alright, Rusty here. Let’s talk about what’s on the cards for Ilbaritz - Edouard VII.
First up, the water is 73°, which is 4° warmer than usual. That’s a fair bit toastier than normal for this time of year, so you’ll be leaving the thick rubber at home.
The first few days are a write-off. Monday and Tuesday are poor, with onshore or cross winds, weak little swells and a cross-chop. Not worth paddling out. Wednesday is similar, with rain showers and messy lines.
Then Thursday the 17th morning things get interesting. A groundswell from the NW with a period of 11 seconds and a height of 6 ft rolls in. The wind goes glassy – dead calm – and the energy jumps right up (663). That means clean, lined-up waves stacking on this reef. It’ll be on the stronger side for an intermediate surfer, but the glassy conditions will make it feel much better. If you can handle a bit of power, this is the first real highlight of the run.
Friday the 18th is a step back with onshore winds and chop, so sit that one out.
Now, the absolute standout. Saturday morning, the 19th of September. That’s your session. The swell pulses to 7 ft from the NW, with a period of 13 seconds. Combined energy reads 1514 – that’s serious, powerful groundswell. Winds are light offshore from the east at 3 mph, and it’s described as clean. This is excellent for experienced surfers only – that size and period on a reef will demand respect. If you’ve got the skill, it’s the best wave of the whole outlook.
Sunday morning the 20th is still fun with a glassy 5 ft, 12-second swell (528), perfect for a longboard or a step-down.
Monday the 21st and Tuesday the 22nd mornings also serve up glassy conditions with solid 4 ft to 5 ft swell from the NW. These are good, clean sessions where you can find your rhythm.
After that, the swell fades. The last week of September is small and mostly poor. Thursday the 24th is tiny at 1 ft. Friday the 25th morning has a brief return of clean 4 ft groundswell (12 seconds), and that’s worth a look if you’re itching for a glassy, cruisy morning. But the end of the run is all onshore wind and flat conditions – not much to chase.
Overall, peak is Saturday the 19th morning. Don’t miss it if you want power and perfection. Thursday the 17th morning and the glassy mornings of the 20th, 21st, and 22nd are your solid fallback options.
Rusty, signing off.
