The Lowdown
Alright, Rusty here, checking the waves for the next couple of weeks. The water’s sitting at 75°, which is a good 5° warmer than usual for this time of year – that’s a serious anomaly, so you’re swimming in bathwater.
We’ve got a solid run starting this Saturday, the 29th of August. The absolute standout is the Saturday morning session at Ilbaritz - Bora Bora. It’s a reef break, fairly consistent, and wide open to the ocean. The swell is a clean 6ft from the WNW, with a 9-second period, and the wave energy is pumping at 641. The wind is a glassy easterly at 3 mph. This is the best of the whole outlook – clean, solid, and perfect for an intermediate surfer. Crowds are likely, so be early.
Saturday afternoon gets a little cross-shore, dropping to 5ft. Sunday the 30th morning is another good one: glassy, a 5ft NW swell at 10 seconds, and 490 energy. Clean. Sunday afternoon turns choppy.
Monday the 31st is another morning winner – dead calm, 5ft NW swell at 9 seconds, 433 energy. Tuesday the 1st of September keeps the pattern: a clean morning with 5ft NW swell at 10 seconds, 392 energy, and a light breeze.
Then the surf drops off. Wednesday the 2nd has only 3ft, and from Thursday the 3rd through the 5th, it’s tiny and low energy. There’s a gap. We get a little pulse on Saturday the 5th of September morning: dead calm, 4ft NW swell at 10 seconds, 273 energy. A small but clean window.
Sunday the 6th of September morning is also clean – glassy, 4ft NW swell at 11 seconds, 414 energy. The longer period will give you better shape, but it might run a bit straight on the reef.
From Monday the 7th onward, the wind goes onshore and the quality is gone. Some small clean windows on the 9th and 10th, but the swell is only 2ft to 4ft with weak energy. The rest of the outlook through the 13th is flat and windy.
Bottom line: the best surf of the 16 days is Saturday morning, the 29th of August, at Ilbaritz - Bora Bora. After that, the mornings on the 30th, 31st, and 1st are solid, and the 5th and 6th of September have clean but smaller waves. Don’t sleep on that first window.
Rusty.
