The Lowdown
G’day, Rusty here. Let’s look at the next couple of weeks for Ilbaritz – Bora Bora. This is a reef break that’s wide open to the swell and pumps out waves fairly consistently for the intermediate surfer. The water is a very warm 74° – much warmer than usual for this time of year, so you’ll be comfortable in boardshorts or a spring suit.
First up, Saturday morning, September 5th. We’ve got a clean 3ft NW swell with a 9-second period and a light offshore breeze from the ENE. The combined energy is moderate at 229, and it’s going to be clean and fun. Saturday afternoon sees the swell jump to 5ft from the NW with a longer 13-second period, but the wind goes cross-shore and energy hits 732. It’s a bit more powerful, but tide might mess with it, so the morning is your call.
Sunday the 6th is cross-on and onshore all day – not worth it. Monday the 7th and Tuesday the 8th are poor with onshore winds and messy conditions.
Come Wednesday morning, September 9th – this is a standout. Glassy, calm wind, 3ft NW swell with a 12-second period, and energy at 455. Clean, lined-up, and beautiful. Thursday the 10th morning is another cracker – glassy again, 4ft NW swell, 11-second period, light air, energy at 332. Both mornings are top-notch, but the afternoons get choppy with cross-on wind.
Friday the 11th through Saturday the 12th are small and weak – swells under 3ft, onshore or cross winds, energy dropping to 94. Not worth the paddle.
Sunday morning, September 13th, is a gem – glassy, 4ft NW swell, 12-second period, energy at 435. That’s a solid session. Afternoon goes cross-on again.
Monday the 14th has a clean morning with offshore wind and 3ft NW swell – ordinary but okay. Then from Tuesday the 15th to Wednesday the 16th, it’s tiny – swells barely 1ft to 2ft, energy as low as 52, mostly onshore. A real quiet stretch.
Thursday morning, September 17th, cleans up – offshore ESE breeze, 3ft NW swell, 11-second period, energy at 218. Nice little session. Friday the 18th stays clean with small 3ft to 3ft waves and glassy periods.
Saturday afternoon, September 19th, looks good – clean cross-offshore breeze, 4ft NW swell, 10-second period, energy at 241. Another solid option.
The real highlights are Wednesday the 9th, Thursday the 10th, and Sunday the 13th mornings – all glassy, clean, and with decent energy. Waves are mostly waist to chest high, good for intermediates. The reef handles the NW groundswell well, with long-period stuff giving nice shape but longer lulls. Crowds are often here, so expect company.
Rusty.
