The Lowdown
G'day, I'm Rusty. Let's get into it.
Alright, the next couple of weeks at Ilbaritz - Bora Bora are a bit of a mixed bag, but we've got some real gems hidden in there if you're patient. The water is sitting at a very warm 74°, which is much warmer than normal for this time of year, so you'll be in boardies or a thin spring suit.
We kick off on Wednesday the 2nd of September with a tiny bit of swell, but the morning is the only real chance. The wind is glassy, calm as, with a small 3ft NW swell, but with only 8 seconds between waves, it's short-period stuff and the energy is weak (120). The afternoon turns to a cross-shore mess, so don't bother.
Thursday the 3rd is flat and forgettable. Friday the 4th has a glassy morning with a tiny 2ft WNW swell, but it's so small it's barely worth a paddle. The energy is very weak (58).
Now, Saturday the 5th is where we see our first real glimmer. Saturday morning is glassy with a 3ft WNW swell, period creeping up to 9 seconds, and the energy jumps to a moderate 206. It's clean, but still small. The afternoon sees a jump in size to 5ft from the NW, with a 12-second period, giving it proper groundswell grunt (614), but the wind turns cross-onshore and chops it up, so it's a bit of a tease.
Sunday the 6th is a write-off with onshore winds. The start of the following week is also poor, with moderate breezes and poor conditions. Wednesday the 9th through to Friday the 11th are all messy with cross-onshore winds, so you're not missing much.
Look ahead to the real standout. Saturday the 12th of September starts to show some promise. The morning is glassy with a 4ft NW swell, but the energy is still moderate (177). The real action kicks off on Sunday the 13th of September. The morning is glassy, with a 4ft NW swell, a 13-second period, and the energy is strong at 989. This is a proper groundswell, and the conditions are set to be very good. This is your best bet for the whole forecast, but keep in mind the long-period swell (13 seconds) can make a beach break a bit straight, but this is a reef, so it should handle it beautifully. It's a bit punchy for beginners at 4ft, so it's better suited to the intermediate crew.
Monday the 14th is also good, with a glassy morning and a 5ft NW swell (413), but the real gem is Tuesday the 15th of September. The morning is clean with offshore winds from the east, a solid 5ft NW swell, an 11-second period, and strong energy (627). This is another standout. The wind is light and off, so expect clean, lined-up waves. This is a bit of a step up in size, so it's more for the confident surfer.
Thursday the 17th of September morning sees a clean cross-offshore breeze, with a 4ft NW swell and moderate energy (296), making for a solid end to the run.
So, to sum it up: the first week is mostly a bust. The standout windows are the glassy mornings of Sunday the 13th and Tuesday the 15th of September. Those are the days to circle on the calendar. Get amongst it.
Rusty.
