The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up for Ilbaritz - Bora Bora.
Right off the bat, it’s a bit of a slow start. The first few days are looking pretty average, with small, weak swell and mostly onshore winds messing things up. The water is a proper 77° – that’s 6° warmer than usual for this time of year, which is pretty wild. You’ll be sweating in your wettie.
The first real chance to get a wave that’s worth talking about is on Saturday morning, August 22nd. We’re looking at a clean 4ft swell from the NW with a 9-second period, and the wind is glassy. It’s not a massive day, but the energy is there (241) and the conditions will be smooth. The reef should be working nicely.
Then things get a bit messy again until we hit Sunday morning, August 23rd. That morning we’ve got a 3ft NW swell, but the wind is offshore from the ENE at 9 mph, which will clean it right up. The energy is weak (94), so it’s small, but it’ll be a fun little session if you’re on a longboard or a fish.
The standout of the whole outlook is hands down Friday morning, August 28th. The swell is up to 7ft from the NW with a 10-second period, the energy is strong (816), and the wind is glassy from the WSW. That’s proper, clean, powerful surf on the reef. It’s a bit big for beginners, but for intermediates and up, that’s the morning to circle.
The next real highlight is Wednesday, September 2nd. The morning starts with a 6ft NW swell, clean with a cross-offshore breeze from the ESE at 6 mph. The afternoon goes glassy with a 5ft NW swell. Both sessions have solid energy (664 and 520) and clean conditions. That’s a full day of quality reef waves.
There’s a big swell forecast for September 1st – 12ft from the NW with a 12-second period – but the wind is cross-onshore, so it’ll be a bit messy. That’s expert territory only, and even then, not ideal.
The crowds at Ilbaritz can be an issue, so expect company on the standouts. The place is a reef, so the long-period groundswell (like the 12 and 13-second stuff) will wrap in nicely, but it can get a bit straight at times. For the best of the best, I’m going with Friday morning, August 28th and Wednesday, September 2nd. These are the ones you want to plan for.
Rusty.
