The Lowdown
G'day, it's Rusty. Let's run through what's cookin' at Ilbaritz - Edouard VII, a reef break that's best for intermediates and exposed to the west. The water's 77°F—that's 5°F warmer than the usual for this time of year, so you'll notice the difference.
The first few days are a dud. Thursday the 20th starts cloudy with a light cross-onshore, swell around 4ft from the NW, but the energy's weak (384). Afternoon brings rain and chop. Friday's the same story—rain, bumpy conditions, swell up to 6ft but the wind ruins it.
Then Saturday the 22nd morning—here we go. Clear skies, a solid 12 mph offshore easterly, and clean 4ft NW swell. The energy's moderate (241) and the period's short at 9 seconds, but that offshore wind on a reef makes for tidy, lined-up waves. This is the highlight for the first week. Crowds are often, so be early.
Sunday the 23rd morning is still clean with a light offshore, but the swell drops to 2ft and the period's only 7 seconds—weak energy (63). It's surfable, just average. Then it goes flat. Monday and Tuesday are tiny, energy in the single digits. Wednesday the 26th morning has a small pulse of 4ft WNW swell with light offshore, clean, but it doesn't last—afternoon brings lumpy conditions.
Looking ahead, Thursday the 27th morning is a stunner: glassy, 5ft WNW swell, energy at 284. Short period, but that glassy surface makes it sweet. Friday the 28th morning is the real standout—flat calm, glassy, 6ft WNW swell and energy at 643. That's solid, good-sized waves, period at 10 seconds, so there's some grunt. This is the one to aim for. Short window, though—afternoon gets messy.
After that, Saturday the 29th is onshore and messy, Sunday the 30th morning cleans up with offshore easterly and 5ft NW swell, but Monday the 31st goes back to poor. Into September, Tuesday the 1st morning has a bigger pulse—6ft NW swell, energy at 821—but the wind's cross-onshore, so it's marginal. The rest of the first week of September fades to under 3ft with onshore winds.
So, the best bets: Saturday 22nd morning for the clean offshore, and Friday 28th morning for the glassy, bigger swell. Don't sleep on it.
Rusty.
