The Lowdown
Alright crew, let’s talk about In Betweens. The first week or so is a bit of a bust, to be honest. We’ve got a long gap with no real surf to shout about. The wind is howling out of the ENE, cross-off, which keeps the surface looking alright, but the swell is tiny and gutless. You’re looking at waves around 2ft, with barely any energy behind them. The water is sitting at 80°, which is pretty normal for this time of year, so at least a dip won’t be a shock.
From the 16th through the 19th, it’s a write-off. The swell is small, the period is short, and the combined energy is weak. It’s just not worth the effort. The wind stays breezy, and the waves are poor.
We get a little flicker of life around the 20th and 21st, with the swell picking up a bit (energy gets into the 600s), but it’s still only around 3ft and the quality is marginal. The direction swings to the S, which isn’t what this reef wants to see. It’s a tease, not a treat.
Now, the big one. Mark your calendar for Tuesday the 28th. That’s the standout. The ENE swell is going to pump in at 10ft, with a 14-second period. The combined energy is through the roof (3667) – that’s strong, powerful stuff. The wind drops to a light breeze from the ENE, giving us clean, lined-up waves. This is a reef break, so that long-period groundswell is going to wrap in beautifully, but it’s going to be big and powerful. Experts only, no question. The crowds are "sometimes" a thing here, but on a day with that kind of size, you might have a few more in the lineup, but the waves will be worth the wait.
The day before, on the 27th, is a solid warm-up with 5ft surf, but the 28th is the real deal. After that, it fades hard, so get on it while you can.
Stay patient, and don’t waste your energy on the small stuff.
