The Lowdown
Imperial Version
Alright, let’s get into it. The first week is a total bust. We’ve got a big gap from now until the 19th of August with nothing worth your time. Just tiny NW ripples, 0.7 ft to 3 ft, with cross-onshore breezes and wave energy that barely hits 62. It’s a slow start.
On the morning of Thursday the 20th of August, we get a little flicker. A clean 4 ft NW swell with an 11-second period and glassy conditions. The energy is moderate at 281. It’s a nice window, but the wind goes cross-onshore by the afternoon.
Friday the 21st of August morning is your first real call. The swell is 5 ft from the NW, period at 10 seconds, and it’s glassy. The energy is solid at 444. That’s the cleanest it’s going to be in the first week.
The 22nd and 23rd offer some ordinary but surfable waves. The 22nd morning has a clean 3 ft NW swell with light offshore wind (158 energy), and the 23rd morning has a glassy 2 ft NW swell (74 energy).
Then it goes quiet again from the 24th to the 27th. The 28th of August Friday afternoon sees a jump to 8 ft from the WNW, but it’s cross-onshore, so it’s messy.
Now, the big event. Saturday the 29th of August morning. This is for the experienced crew only. A massive 15 ft NW swell with a very long 14-second period, glassy conditions, and wave energy roaring at 7039. This is not for beginners. The long period will make the sets powerful and the reef at Ilbaritz - Bora Bora will be the place to be.
The 30th of August morning has a 8 ft NW swell that’s marginal, and the 31st is just a mess with 30 mph winds. The first of September is still lumpy.
Water temp is 25°, which is a full 3° warmer than normal, so you’ll be in a spring suit at most.
Rusty out.
