The Lowdown
Alright, this is Rusty. Let’s break down what’s coming up for the next couple of weeks.
We start off flat and poor. The first few days through Monday and Tuesday are basically a waste of wax. Tiny waves, dirty conditions. There’s a big gap of several days with no real surf before anything decent shows.
The first flicker of life comes Wednesday morning, August 26th. Ilbaritz - Bora Bora is glassy and calm, but the swell is only 2ft from the WNW with a short period. Combined energy is light (56). It’s rideable but forgettable – maybe a warm-up for beginners.
Thursday morning the 27th is glassy again but the swell is smaller. Not worth it. Friday the 28th sees the swell build to 5ft from the WNW, but the wind is ugly and onshore. Energy is ramping (349) but the quality is gone.
The first real standout is Saturday morning, August 29th. This is the one to circle early. We get 5ft of NW groundswell at 9 seconds, and the wind is dead calm – glass. Combined energy is solid (338). Ilbaritz will be clean and fun. Water temp is running 76°, which is much warmer than usual for this time of year. Expect crowds to be often here.
Then we have the big one: Tuesday morning, September 8th. This is a heavy hitter. Swell is 4ft from the WNW, but the period is a massive 19 seconds – that’s very long period groundswell. Combined energy is a thumping 1187. Wind is light cross-offshore from the SE, so it will be clean. This is expert territory only. That long period will line up beautifully on this reef, but it’s going to be powerful. This is the session to plan for.
In between, there are some other workable glassy mornings – Sunday the 30th with 4ft, Monday the 31st with 5ft, and Tuesday September 1st with 5ft – all clean and worth a look. But nothing beats that Tuesday the 8th.
After the big day, things drop off quickly. The 3rd and 4th bring rain and onshore winds, making a mess. By Monday September 7th, we get clean offshore wind and 4ft of swell, but it’s a distant second compared to that Tuesday highlight.
Summary: The first week is mostly empty except for that Saturday glassy session. The real treasure is waiting in the second week – that Tuesday September 8th morning is a monster in the making. Everything else is just background noise.
Rusty.
