The Lowdown
Alright, listen up. The surf around Rabbit/Manana Island is looking pretty lackluster for the next couple of weeks. It's a stretch of poor, lumpy conditions for the most part. Water temp's about average for this time of year at 27°, so it's not a factor.
Your one real window of hope shows up on Sunday, August 30th. The swell should be a solid 8ft from the ENE, and the period stretches out to a better 9 seconds, which is a whole lot better than the 6 and 7 second junk we'll see before that. The combined swell energy is pushing 1019, so there's some moderate power there, but the wind is still fresh and cross-shore, making it lumpy. It’s not going to be glassy, but it's the only day worth paddling out for. This is your standout, but it's more than a week out, so call it promising but not a done deal.
Before that? Don't even bother. From now until the 29th, it's a long stretch of small, weak surf. Wave heights mostly under 7ft, short periods, and that relentless cross-onshore wind. It'll be choppy and messy with no drive. There are days with zero on the scale, so you could leave the board in the truck for a week and a half.
As we get into the last few days, the swell does start to jack up with some serious energy. On the 28th and 29th, we're looking at swell over 10ft with energy readings climbing past 1000, but the wind stays messy and cross-onshore. That's a lot of water moving around with a rough surface. With the swell coming from the ENE and the spot being exposed to the NNE, it's not going to be breaking at its best either. This is getting into expert-only territory size-wise, and with that wind, it's going to be blown out. This might be more interesting for the kite surfers than us.
So, there you have it. One window of potential on the 30th, and a bunch of flat and messy days to get through first. Don't hold your breath, but keep an eye on it.
