The Lowdown
Alright, Rusty here, let's break down what's in store for Ilbaritz - Edouard VII.
First off, the water is sitting at a balmy 73°, which is about 4° warmer than normal for this time of year. That's a nice little bonus while you're waiting for a set.
The surf starts up this Sunday, September 13th, with a promising morning. We've got a clean 4ft swell coming from the NW with a long 13-second period. The wind is glassy out of the east at 3 mph, making for some real clean conditions. The wave energy is moderate, sitting at 545. This is a solid, inviting start. The afternoon sees a shift to a cross-shore NNW wind at 6 mph, which will still be rideable, but the morning is the clear pick.
Monday the 14th is another morning option with glassy ENE winds at 3 mph and the same 4ft NW swell, though the period has dropped a bit to 11 seconds and energy is a little lower at 453. It's still a good session, but the afternoon gets blown out by a stronger cross-shore wind.
Tuesday and Wednesday look like write-offs with onshore winds and poor conditions. A bit of a lull.
Now, Thursday the 17th is where we get a proper standout. The morning is absolutely prime: glassy NNE winds at 3 mph, a 6ft NW swell with an 11-second period, and moderate to strong wave energy at 676. This is a session to mark on your calendar. The swell is getting a bit sizeable for beginners, but for intermediates and up, it's going to be excellent.
The next real highlight is Saturday, September 19th. We’re looking at a 7ft NW swell with a long 13-second period, pushing strong to very strong wave energy at 1643. The morning is glassy with a light ESE offshore breeze at 3 mph. This is definitely a session for experienced surfers only at that size, but the quality is off the charts. The afternoon will still be good, but a cross-shore wind will put a bit of texture on it.
Sunday the 20th holds clean conditions again with offshore east winds in the morning and a 5ft NW swell, 12-second period. Solid, clean surf all day.
Monday the 21st is another cracker for the experienced crew: a 6ft NW swell, 13-second period, and glassy conditions with zero wind in the morning. Wave energy is strong at 1069. This is going to be a memorable morning.
After that, we have a few days of onshore wind and choppy surf, until Wednesday the 23rd when a clean, cross-offshore NE breeze returns with a 5ft NW swell. That’s a good session.
The swell tapers off towards the end of the month. Friday the 25th has a smaller 3ft NW swell with clean offshore east winds – a fun little cruiser session for the longboard or a twinny.
So, the standout days are definitely the mornings of Thursday the 17th, Saturday the 19th, and Monday the 21st. Mark them in the book. The rest has its moments, but those are the ones to chase.
Rusty.
