The Lowdown
Alright, Rusty here again. Let’s run through it in feet, miles per hour, and Fahrenheit. The story’s the same: the first ten days or so are a dead loss. From August 14th right through to the 24th, we’ve got nothing but poor surf at Ilbaritz - Bora Bora. Waves are tiny, wind is mostly onshore or cross-on, and the swell energy is weak. The water is 77°F, which is about 5°F warmer than normal for this time of year – that’s a pretty big anomaly, feels like a warm bath, but the surf is just not there. Even on the 18th and 19th when it goes glassy, the waves are only 0.7ft to 1ft. Not worth the walk.
We finally get a pulse on Thursday, August 22nd. Morning brings offshore wind from the ENE at 6 mph, and clean little 3ft waves from the NNW. The energy is still low (62). It’s surfable, but not special. The afternoon gets messy again with cross-shore wind.
The real standout, and I mean the only one, is Thursday, August 29th. That morning we’ve got a 5ft NW swell with a 9-second period (short period), and the wind is offshore from the ESE at 6 mph. It looks clean. The combined swell energy reads 379 (moderate energy). By the afternoon, it’s still a clean 5ft NW swell with offshore wind. That’s where you want to be. After that, Friday the 30th gets hammered by strong onshore wind (19 to 22 mph) and a lumpy 6ft to 8ft NW swell. Saturday the 31st of August sees a 10ft NW groundswell with a long 13-second period – that’s huge energy, 3527 (very strong) – but it’s all cross-on and choppy. Only for experts, if anyone’s mad enough.
Stick to Thursday the 29th of August. That’s the day. Everything else, leave it.
Rusty.
