The Lowdown
Hey, Rusty here. Looking at Ilbaritz - Bora Bora for the next couple of weeks. This reef break wants clean NW groundswell and light winds to work its magic.
No surf to start. The first real action is Sunday, September 13th in the morning. Swell about 4ft from the NW, 13-second period, and the wind is glassy from the ENE. Clean, well-shaped waves for the reef. Water temp is 73°F, much warmer than normal for this time of year. The combined energy is moderate at 545.
Monday the 14th morning is similar—4ft NW swell, glassy—but the period drops to 11 seconds. Still okay.
Tuesday and Wednesday are small and messy with onshore wind. Not worth it.
Thursday the 17th morning is a highlight. Swell builds to 6ft from the NW, 11-second period, and glassy wind from the NNW. Clean, moderate energy (663). Good for experienced surfers.
The absolute best is Saturday the 19th in the morning. Swell hits 7ft from the NW, 13-second period, with offshore wind from the ENE at 5 km/h. The combined energy is strong at 1619. This is a powerful, clean groundswell for the reef—experts only. Crowds are possible.
Sunday the 20th and Monday the 21st still have solid 6ft to 7ft swell, but the wind gets tricky. Mornings are cleaner.
Into the second week, mornings stay clean with ENE offshore winds and NW swell around 4ft to 5ft. Friday the 25th is a good one—5ft NW swell, 13-second period, and a cross-offshore breeze from the SE.
The standout is Saturday the 19th. Second best is Thursday the 17th. Get after it.
Rusty.
