The Lowdown
Alright, Rusty here. Let’s take a look at what’s on the table for the next couple of weeks.
To be straight with you, the outlook is a bit of a lean stretch. We’ve got a solid week with essentially no surf worth a paddle. From Friday the 14th through to the 19th, the swell is tiny and the wind is mostly onshore or cross-onshore, making for poor conditions. It’s a bit of a flat spell, and it feels like the ocean is just resting.
The first real chance we see is on Thursday morning, the 20th. Ilbaritz - Bora Bora will have a glassy start with a 2ft swell from the NW. The period jumps up to a long 12 seconds, so there’s some grunt in the water, and the combined swell energy is moderate at 117. The water is sitting at 75°, which is 4° warmer than normal for this time of year, so it’s notably warm. Still, the waves are small and the conditions are only just surfable. Nothing to get too excited about.
The real standout window looks to be Friday morning, the 21st. We see a jump to 5ft from the NW, with a long period of 11 seconds. The combined energy hits a strong 416, so there’s a fair bit of power in the water. The wind is light and onshore from the WNW, which isn't perfect. The swell direction is NW, matching the optimum W direction reasonably well for this exposed reef. This is the best looking surf in the whole forecast, but it’s still marginal. If you’re an intermediate, it’s worth a look, but don’t expect perfection.
After that, the energy drops off. There’s a brief glassy moment on Monday the 24th with a 4ft swell from the NNW, and again on Tuesday the 25th with a similar 4ft NNW swell. Both mornings have glassy conditions, but the period is a short 7 to 8 seconds, so the waves will be a little weak and crumbly. The energy is moderate, around 113-170. These are just surfable, but not special.
The very end of the window, on Friday the 28th, offers a 3ft NW swell with a 9-second period, and glassy conditions in the morning. The combined energy is moderate at 196. Again, it’s a small, clean option, but nothing that will blow you away.
Overall, Friday the 21st morning is your best bet. It’s got the most size and power. Don’t get your hopes up too high, as it’s still a marginal day. The rest of the period is a waiting game for better swell.
