The Lowdown
Alright, mate, Rusty here. Let’s get into it.
We are looking at Ilbaritz - Bora Bora, a reef break out here. The water is sitting at 77°F, which is a solid 5°F warmer than usual for this time of year – that’s a real treat, feels like a bath.
The window starts off pretty slow. Thursday the 20th of August has a bit of swell, about 4ft from the NW with 11-second period and moderate energy (384), but the wind is onshore and the conditions are messy. Honestly, you can leave the board in the car for the first couple of days. There’s a run of poor surf with onshore and cross-onshore winds that kills the vibe through to Friday.
Now, Saturday morning the 22nd of August is where things start to look up. We get a clean 4ft NW swell with a 9-second period, and the wind swings to a moderate offshore from the east. The energy is light (241), but it’s clean and the break will have some shape. It’s not a standout, but it’s a solid start.
The real standout window, though, is the morning of Wednesday the 26th of August. The swell picks up to 4ft from the WNW, still 9 seconds, but the wind is a light cross-offshore from the southeast. The energy is moderate (241), and the conditions are clean. This is a good chance for some fun, lined-up waves at the reef.
Then, hold onto your board, because the morning of Friday the 28th of August is the pick of the whole forecast. We’ve got a 6ft NW swell with a 10-second period and strong energy (643). The wind is dead calm – glassy as can be. This is the kind of morning that makes you wake up early. The reef will be handling that groundswell nicely, with clean, punchy waves. It’s the best on offer, hands down.
After that, the swell drops off and the wind turns messy again through the end of August and into early September. There’s a promising blip on the morning of Tuesday the 1st of September, with a 6ft NW swell and 11-second period, but the cross-onshore wind keeps it from being a full standout. It’s worth a look if you’re keen, but don’t expect perfection.
The rest of the first week of September is a slow fade into small, weak surf with poor winds. The energy drops right off, and it’s not worth chasing.
So, to wrap it up: the period starts slow, builds to a couple of clean mornings, and peaks with a spectacular glassy session on the morning of Friday the 28th of August. After that, it’s a waiting game.
Rusty.
