The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks for Ilbaritz - Bora Bora.
To be honest, it’s a pretty slow start for a reef break that’s wide open to the west. We’ve got a few days of tiny, weak swell right now, and the first real chance of anything worthwhile doesn’t really kick in until the weekend. The water is sitting at 76°, which is much warmer than normal for this time of year, so that’s a nice bonus.
The first session that actually gets my heart rate up is Saturday morning, August 29. The wind is offshore from the east at 6 mph, the swell is a clean 6 ft out of the northwest with a period of 9 seconds, and the combined energy is a solid 481. That’s a good, punchy wave for an intermediate. The afternoon turns a bit cross-shore, so get on it early.
Then Monday morning, August 31, looks like another gem. The wind is glassy from the northeast, the swell is 6 ft from the northwest, and the energy is 470. It’s clean, it’s got some push, and the conditions are lined up for a fun session. The reef will be handling that long-period energy well, though it does mean longer waits between sets.
Tuesday morning, September 1, is also worth a look. Glassy wind, 4 ft of northwest swell, and the energy is 364. It’s a bit smaller, but still clean and surfable.
Now, the real standout for the whole 16-day window looks like Wednesday morning, September 9. The wind is dead calm, glassy as a mirror, with a 4 ft northwest swell and 9-second period. The energy is 255, and the conditions are just about perfect for the reef. This is the kind of morning you call in sick for. The wind is offshore, the water is smooth, and the waves will be peeling.
After that, the swell tapers off into the second week, with smaller, more ordinary conditions and more cross-onshore winds. The last few days from September 5 onwards are mostly poor, with onshore winds and dropping energy, so don’t expect much.
For the very best on offer, I’d put Saturday morning, August 29, and Wednesday morning, September 9, up there as the two standouts. The 9th is the one to circle on the calendar, but keep in mind it’s over a week out, so the forecast could shift. The crowds are often a thing here, so you might have some company, but for those clean windows, it’ll be worth it.
Rusty.
