The Lowdown
Alright, Rusty here again, giving you the same read, but in feet and miles per hour.
We’re starting off slow for Ilbaritz - Bora Bora. The first couple days are small and messy. The best early look is Friday the 4th morning: a tiny 2 ft WNW swell, but the wind is glassy, so it’s clean. The energy is weak (58), so you’ll be on a longboard just getting a few.
Now, Saturday the 5th morning is a real standout. The swell jumps to 2 ft from the NW, with a very long 14-second period, and the energy is strong at 310. The wind is dead calm – glassy. That’s prime groundswell for a reef break. It’s a fairly consistent spot, but expect a crowd, as it’s often busy. This is the best session of the first week.
Sunday the 6th morning is also great. The swell is 5 ft from the NW, 12-second period, and the energy is strong at 607. The wind is glassy again, with a light breeze from the ENE. The water temp is about average for this time of year. This is a solid session for intermediate surfers.
The next week drops off, but Tuesday the 8th morning has 4 ft of WNW swell with clean offshore wind from the NE and moderate energy (333). It’s a decent option.
Looking way out to Monday the 14th, we’ve got a big pulse. Monday morning shows 5 ft of NW swell with a very long 15-second period, and the energy is a massive 1124. The wind is light onshore from the W, so it could be a bit bumpy. The afternoon is even bigger at 6 ft, but the wind is cross-on. That’s expert territory, and the long period will make the reef break well. It’s promising, but the long-range outlook is less certain.
The clear winners are Saturday the 5th and Sunday the 6th mornings – clean, glassy, with solid groundswell energy. That’s where you want to be.
Rusty.
