The Lowdown
Alright, let me get into this. The 16-day window for Ilbaritz - Bora Bora is a slow burner, but there are some real gems in there for the patient crew.
The first few days are a bit of a write-off. The swell is tiny, and the strong offshore wind on Tuesday, September 1st, is good for shape but the swell is just too small. The real action starts to build from the 5th.
Saturday, September 5th is the first standout. The morning at Ilbaritz - Bora Bora is absolutely glassy, with a calm wind and a clean 4 ft swell from the NW. The period is a solid 11 seconds, meaning it's a proper groundswell with some grunt. The combined energy of all swells is moderate (258). This is a proper window for clean, lined-up waves. The water temperature is about average for the time of year, so just standard boardies weather.
Sunday, September 6th is even better for the morning session. The swell is up to 4 ft, again from the NW, with an 11-second period, giving it a moderate energy of 391. The wind is calm and glassy. The waves should be clean and consistent. This is another top-tier morning.
The following week, from the 10th to the 13th, the swell bumps up again, but the wind gets messy. Thursday morning the 10th has a 5 ft NW swell, but the wind is side-shore, creating a slight chop. It’s surfable, but not the clean glass of the weekend. The energy is strong (334). The best call is to stick to the morning windows if you can, as the afternoons are generally cross-shore or onshore.
The true standout is the weekend of the 5th and 6th of September. The early morning glass, the NW groundswell, and the moderate energy will give you the best chance of a clean, classic reef wave. This is a fairly consistent spot, and the crowds are often around, so get there early.
