The Lowdown
Alright, let’s talk about the surf in terms you can feel. This is Rusty, and I’m looking at the 16-day window for Ilbaritz - Edouard VII, a reef break that’s all about that west swell exposure.
Straight up, the first few days are a bummer. Thursday the 20th and Friday the 21st bring rain and choppy cross-onshore winds, with moderate energy levels (441 and 724). The water is a warm 77°, which is much warmer than average for this time of year, so you’ll be comfortable in a shorty.
The first real chance of a good session is Saturday morning, August 22nd. The wind goes offshore from the east at 12 mph, cleaning up a 4ft NW swell with a 9-second period. Combined energy is moderate (269). It’s not huge, but the clean conditions make it the best early option. Crowds are often an issue, so expect a lineup.
Sunday the 23rd is a letdown – just 2ft of weak swell (62 energy) with a 7-second period. Then we get a long gap from Monday the 24th through Wednesday the 27th, with almost no surfable waves. Poor conditions across the board.
Looking ahead, Friday morning, September 4th, is a long-range standout. We’ve got a 5ft NW swell, an 8-second period, and glassy offshore winds from the northeast. Combined energy is moderate (281). This is the one to wait for – clean, punchy, and with some potential. The afternoon on the 4th is still okay, 5ft NW swell (402 energy), but wind turns cross-shore, so it’s less perfect.
The rest of the second week is mostly small, choppy, or onshore junk. Wednesday, September 2nd morning could give you a tiny 3ft WNW swell with clean cross-offshore winds, but it’s ordinary.
Best on offer: Saturday morning, August 22nd, for the clean offshore conditions and a solid 4ft NW swell. And if you’ve got patience, Friday morning, September 4th, with glassy conditions and a 5ft NW swell, is the other real gem.
