The Lowdown
Alright, Rusty here. Let’s have a look at what we’ve got lined up for the next couple of weeks at Ilbaritz - Edouard VII. This is a reef break, exposed and ready to take a sniff of any west-northwest swell that comes its way.
Right off the bat, the first few days aren't looking like much. Saturday the 12th is a write-off – tiny little 2ft swell, short period, and a messy cross-shore wind. The water is way warmer than it should be for this time of year, which feels a bit weird, but it’s not helping the waves any. We’ve got a bit of a flat spell to start.
But hold tight, because the real story starts late on Sunday the 13th. Sunday morning is where it first gets interesting. We’ve got a clean 4ft groundswell rolling in from the northwest, with a solid 13-second period pushing strong energy (545 combined energy). And the wind? Glassy, out of the northeast at just 3 mph. That’s the kind of stuff that makes a reef come alive. Clean faces, decent push – this is the first real standout of the outlook.
Sunday afternoon gets a bit of cross-on breeze and the quality dips, but Monday the 14th morning is another quiet gem: glassy again, 4ft NW swell, 11-second period. Not the biggest surf, but the conditions are spotless.
We hit a bit of a lull Tuesday and Wednesday. The swell stays around but the wind turns onshore or cross-onshore, and the quality just isn’t there for a good paddle. Thursday the 17th morning is a sneaky one – glassy, 6ft NW swell with 11-second period. That’s 703 combined energy, and clean conditions. A solid morning session that won’t be too crazy crowded.
Then we look ahead. The standout of the whole period is shaping up for Saturday the 19th. Morning session: 7ft of long-period NW groundswell (13 seconds) with zero wind – dead glass. Combined energy is pumping at 1395. This is a proper reef-swell combo, and for experienced surfers, this is the one to circle. The afternoon gets a bit lumpy with the cross-on breeze, so hit the dawn patrol.
There is another beauty waiting on Monday the 21st. Offshore easterly wind at 6 mph, 7ft NW swell, 14-second period – 1528 combined energy. That’s groundswell perfection. The reef will be holding that line. This is big enough to be expert territory, but if you’ve got the skills, it’s going to be worth the paddle.
Tuesday the 22nd is a repeat but a touch bigger: 8ft, 13-second period, 1862 combined energy, and a clean offshore wind. That’s some heavy energy. Again, experts only, but the quality is rated excellent.
The last few days of the window settle down. Wednesday the 23rd still has clean morning surf at 5ft, but things taper off through Thursday and into the weekend with onshore winds and smaller swell.
To sum it up: the first real call is Sunday morning, but the true standouts are Saturday morning, 19th September and Monday morning, 21st September – both offering clean, powerful NW groundswell on a reef with offshore or glassy conditions. If you can only paddle out once, make it one of those.
Rusty.
