The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking at Ilbaritz - Edouard VII.
The story starts with a bit of a wait. The surf is basically flat or messy for the first few days. Monday the 7th and Tuesday the 8th are a write-off. We’ve got a tiny bit of energy but the wind is all wrong, and the conditions are just poor. You’re not missing anything.
The first real sniff of hope comes on Wednesday morning, the 9th. We’ve got a bump in size to 6ft from the NW, but it’s riddled with a cross-shore wind and a short period of 9 seconds. The combined energy is moderate (486), but it’s a bit of a wind-affected mess. Not the one to get excited about.
Thursday the 10th – That’s the standout in the near term.
Thursday morning is the real deal. The wind drops to nothing – glassy. We’ve got clean 5ft NW swell at a solid 10-second period. The combined energy is moderate (392), and the conditions are set to be clean. For a reef break like this, that’s a beautiful window. The water is sitting at 74°, which is much warmer than normal for this time of year, so you can leave the thick wetsuit at home.
After that, Friday the 11th and Saturday the 12th drop right off again into tiny, weak surf with onshore winds. Another gap in the action.
We get a pulse back on Sunday the 13th with a 5ft NW swell and a long 13-second period, bringing strong energy (688). The wind is cross-onshore though, so the quality is marginal. It’s a tease.
The next true standout is Monday the 14th.
Monday morning is a beauty. The swell is 5ft from the NW, period is a nice 12 seconds, and the wind is glassy from the ENE. Combined energy is strong (574). This is a perfect window for a reef break – clean, powerful, and well-shaped. The cross-onshore ruins the afternoons, but that morning session is pure gold.
The rest of the second week gets a bit wild. We see a big jump in size on the 16th and 17th, with 7ft to 8ft NW swell, but the wind is hammering onshore. That’s expert-only territory, and even then, it’s going to be a bumpy, challenging paddle. The combined energy is massive (1351 on the 18th morning), but the wind is poor.
The run of good surf returns the following weekend. Saturday the 19th is a solid call. The swell drops back to a manageable 5ft from the NW, and the wind switches offshore from the E. That’s a clean, 12 mph offshore breeze, and the combined energy is moderate (380). Perfect for a reef setup.
Sunday the 20th morning is another standout. 5ft NW swell, glassy with a light SSW breeze. Combined energy is moderate (477). That’s going to be a long, clean, and fun session. It’s a great way to close out the forecast period.
So, if you’re planning a session, your best bets are Thursday the 10th morning and Monday the 14th morning in the first week, and Saturday the 19th and Sunday the 20th morning in the second week. The long-range stuff is promising, but you know how it is – keep an eye on the wind as it gets closer.
Rusty.
