The Lowdown
Alright mate, Rusty here. Let’s break down what’s coming for the local surf.
So, for Ilbaritz - Bora Bora (reef), the water is sitting at about 77°F, which is a good 5°F warmer than usual for this time of year. That’s pretty unusual, so you’ll be in a warm bath. The first few days are a bit of a dud, with hardly any energy in the water. The swell energy is only at 15, which is weak, and the waves are small and messy. You’ll have to be patient.
The first real chance comes on the morning of Saturday, 22 August. We’ve got a clean 4ft swell from the NW with a period of 9 seconds, and the wind is light offshore from the E. The combined energy is moderate at 241. It’s not huge, but it’s clean and rideable. The afternoon gets a bit choppy, so get out early.
Sunday morning, 23 August, has some small 2ft waves with a light offshore breeze, but it’s weak. The following week is mostly a bust with poor conditions, onshore winds, and messy surf. The best bet for the next week is the morning of Friday, 28 August. We’ve got a clean 6ft NW swell with a 10-second period, and a light offshore ESE breeze. The combined energy is strong at 707. This is a solid groundswell with good shape, and the offshore wind will keep it glassy. It’s a bit of a standout but it’s into the second week, so don’t count on it just yet.
Looking further ahead, the morning of Wednesday, 2 September, looks promising. The swell is 7ft from the NW with a 9-second period, and it’s glassy – calm conditions. The combined energy is strong at 720. That’s a good size, but it’s a fair way out, so keep an eye on it. The morning of Thursday, 3 September, also has some clean 4ft waves with glassy conditions, but the energy is moderate.
Overall, the standout is the morning of Friday, 28 August, with clean, strong surf. The glassy mornings on 2 September and 3 September are also ones to watch. There's a big gap of poor surf from the 24th to the 27th, so plan around that.
Rusty.
