The Lowdown
Alright, this is Rusty, and we're dialing into Ilbaritz - Bora Bora. This reef pass is hungry for west swell, and we've got a slow burn before the main event.
The first few days? Forget about it. Monday and Tuesday (Sept 7th & 8th) are blown out with onshore wind and weak, grovelly waves. Wednesday the 9th has a little more push, but a short 9-second period and cross-shore wind make it a choppy mess. Thursday morning the 10th is the first real chance, with a light cross-offshore wind cleaning up a 4.3ft NW swell at 10 seconds. The energy is moderate (355), so it's rideable, but it's not the session you're waiting for.
The real gold starts the week of the 14th. Monday morning, September 14th, is a stunner. A clean 4.6ft NW groundswell, a 12-second period, and glassy conditions with zero wind. Energy is strong at 603. This is a proper reef-swell, and it's going to be a beautiful, clean ride.
But the absolute standout is Wednesday, September 16th. The morning is a dream. We're looking at a solid 5.2ft of NW swell, a 12-second period, and a light cross-offshore breeze keeping it clean. The energy is pumping at 699. This spot can get crowded—it's "often" busy—but for waves like this, you paddle out and deal with it. The next morning, Thursday the 17th, is also a gem with 4.9ft of glassy swell and 442 energy. Friday the 18th keeps the trend going with another morning of glassy perfection at 5.2ft and 509 energy. That's a solid run of quality.
The second week fizzles out. Saturday the 19th still has clean morning waves, but the energy is fading. By Sunday the 20th, the wind turns onshore and the swell gets messy. It's a case of picking your windows. The water temp is about normal for this time of year, so you're comfortable in a spring suit.
Best bets: the mornings of the 14th, 16th, and 18th. The 16th is the one to circle.
