The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks for Ilbaritz – Bora Bora. This is a reef set-up, pretty exposed to the west, so it needs the right window to really fire. Right now, the water’s sitting at 75°F, which is much warmer than usual for this time of year – you’ll feel that difference.
The start of the period is a bit of a write-off. Monday the 31st has some swell, around 6ft to 6ft from the NW, but the wind is on it or cross-on, and the energy is only moderate (535 to 754). It’s messy. Tuesday morning the 1st of September looks a little cleaner with offshore breeze and 5ft NW swell, moderate energy (400), but it’s still not a standout. Then we hit a real flat spell. From Wednesday the 2nd through to Friday the 4th, the swell drops right off – under 3ft, weak energy, and mostly onshore or cross-shore winds. There’s a big gap of poor surf here.
Now, the real highlight comes around Saturday the 5th of September. The morning is glassy, with a clean 4ft NW groundswell, a very long period of 14 seconds, and the energy is strong at 676. That’s going to produce some proper, well-shaped waves at this reef. The afternoon bumps up to 6ft and the energy surges to 1120, but the wind goes cross-shore, so it’ll get a little sectiony. Still, the morning is the pick. Sunday the 6th also has a glassy morning with 5ft NW swell, 12-second period, and strong energy (723) – another solid session. After that, the swell fades again through the next week, with small, weak waves and mostly poor conditions.
Looking further out, toward Tuesday the 15th of September, there’s a new pulse of 7ft WNW swell, very long period of 14 seconds, and massive energy (1453). That’s a serious swell, but it’s onshore wind and the tide might be questionable, so it’s only for the experienced crew. Wednesday the 16th is similar, with 6ft and strong energy (1198), but again cross-onshore. That’s a promising but uncertain long-range call.
So, for the best of the bunch, I’d say Saturday morning the 5th of September at Ilbaritz – Bora Bora is your standout. Glassy, clean, 4ft NW groundswell, and that reef will handle that long period beautifully. The Sunday morning is also a ripper. Don’t waste your time on the flat days in between.
Rusty.
