The Lowdown
Alright, this is Rusty, and I’m lookin’ at the next couple weeks for Ilbaritz - Bora Bora. It’s a reef break, exposed to the west swell, and it’s a fairly consistent setup. But I gotta be honest with you – the first ten days or so are a tough slog. There’s a big gap of poor conditions right through the middle of the month, so don’t even bother paddling out until the end of the third week.
The water temp is about average for this time of year, nothing to write home about. We’re looking at a long stretch of tiny, weak swell and messy wind. From Tuesday the 11th right through to Saturday the 22nd, it’s mostly small waves, poor surf, and cross-onshore or onshore breezes. The combined swell energy is weak, hanging around 56 to 83 for most of that period, with a few days poking into the low 100s. Not worth the wax. There’s a brief blip on Saturday the 15th afternoon where the energy jumps to 146, but it’s a short-period, onshore mess – steer clear.
Then we hit a real stand-out day. Sunday the 23rd of August is the one to circle. The morning is glassy – light N wind at 3 mph – and we’ve got a solid 7 ft groundswell out of the NW with a period of 11 seconds. That’s a long-period swell, so it’ll be lining up with power and shape. The combined energy hits 1123, which is strong. But listen, at 7 ft, this is not for beginners. It’s expert territory, and the reef will be doing its thing. Expect a serious, clean, powerful wave. You’ll have to share it though – crowds are likely here.
Monday the 24th is still decent, with a cleaner 4 ft NW swell in the morning, and a light offshore from the ENE. That’s a nice window for the intermediate crew. Energy drops to 447, so it’s still got some punch.
Then Tuesday the 25th morning brings a glassy 2 ft, but the period is very long – 12 seconds – so it’ll be a bit sleepy at the beach, but if you’re on the reef, it’ll be smooth and clean. That one’s for the longboard or a fun single-fin.
The rest of the outlook fades back into small, weak energy. Overall, the only real standout is the big Sunday the 23rd – that’s the one you wait for.
Rusty.
