The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cookin’ for Ilbaritz - Bora Bora.
It’s a bit of a slow start, I won’t lie. The first few days are looking messy with onshore winds from the WNW and rain showers making a mess of things. The water is sitting at 77°, which is much warmer than what we usually get this time of year – a solid 6° above the norm, so you’ll be in for a warm one.
The real action starts to show itself on Saturday, the 22nd. The morning is the one to look at. We’ve got a clean 4ft swell from the NW, an easterly offshore breeze, and the combined swell energy is moderate at 241. It’s not massive, but it’s clean and workable. That’s the standout for the first week.
Sunday the 23rd fades quickly, and from Monday the 24th through to the 26th, we’re looking at a gap of three days where the surf is pretty much flat or just too small to bother with.
Things get a bit tricky come Friday the 28th. The morning brings a solid 8ft NW swell – that’s a big one – but the wind is onshore from the west. The combined energy is a massive 1236, so there’s a lot of power in the water, but it’s going to be a mess. This one is for experienced surfers only, and honestly, with that onshore wind, it might be more interesting for the kite crowd than the paddle crowd.
Then we get a couple of nice windows. Saturday the 29th morning cleans up: 5ft from the NW with a light ESE offshore breeze (479 energy). It’s solid and clean. Then Sunday the 30th morning is a beauty – glassy conditions, 5ft NW swell, 365 energy. That is a pure, clean surf window. This is your best bet for the second week.
The long-range stuff up to the 5th of September looks promising but it’s a week and a half away, so keep an eye on it. The morning of the 5th has a 7ft WNW swell, glassy conditions, and a combined energy of 804 – that’s a serious swell. If it cleans up, that could be the best day of the whole forecast, but it’s a long way off.
Stay sharp, check the winds, and don’t sleep on those Saturday and Sunday mornings.
Rusty.
