The Lowdown
Alright, grab your board and listen up. Rusty here, taking a good hard look at what Ilbaritz - Edouard VII has to offer.
First thing you need to know: it’s gonna be a lean run for a while. The start of this outlook is a tough one. We are looking at a stretch of weak, short-period slop and onshore winds. The water is a toasty 77°F, which is 6°F warmer than usual for this time of year. That’s very unusual, but right now, that warm bath is the only thing going for it. There’s nothing worth paddling out for until we hit Thursday the 20th.
Thursday the 20th morning is our first real flicker of life. The wind goes glassy with a light air from the WSW, and we get a jump in energy from a groundswell out of the NW. The combined energy hits 214, which is moderate, and the period stretches to 11 seconds. With that offshore wind, it should be clean. But don’t get excited for long—the afternoon gets ruined by a cross-onshore breeze that chops it up.
Now, Friday the 21st morning looks like the first proper standout. We’ve got a decent 5ft NW groundswell, still with that 10-second period. The wind is a light cross-offshore from the NNE, cleaning up the faces. The energy is solid, hitting 433. This is a reef break (Ilbaritz - Edouard VII), exposed to the west, and that NW swell is right on the money for the optimum direction. This one has good shape written all over it. Keep in mind, 5ft can be a bit much for beginners, but for the intermediate crowd, this is the session to aim for. The volume is up and it should hold some punch.
After that, things get ordinary again. Saturday the 22nd morning has clean surf from an easterly offshore, but the swell drops off. We get a few more days of light, weak surf, small and mostly wind-affected right through the end of the month.
However, if you’ve got patience, the real sleeper is way out on Sunday, the 30th of August into Monday, the 31st. Sunday the 30th morning shows a 5ft NW swell with a period of 12 seconds. The combined energy is a very strong 670. The wind is onshore though, so conditions are going to be messy. It’s lumpy and cross-onshore in the afternoon.
The absolute best bet of the whole outlook is Monday the 31st morning. The swell is still a solid 4ft from the NW, period at 10 seconds, combined energy at a strong 355, and – get this – the wind goes glassy from the WNW. That’s a flat calm, offshore condition for this spot. It’s over a week away, so forecasts can wobble, but if that holds, Ilbaritz - Edouard VII will be offering up some clean, lined-up reef waves. That’s the one to circle on your calendar.
Stay patient, keep an eye on the wind, and I’ll see you out there.
Rusty.
