The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s brewing for Rabbit/Manana Island. I gotta be straight with you – this stretch isn’t giving us much to shout about. The first real window of half-decent surf doesn’t show up until Wednesday, July 29th, so we’re looking at a solid few days of waiting.
The water temp is sitting right around 80°F, which is about average for this time of year, so you won’t need a thick suit.
The one standout in this whole 16-day window is Wednesday, July 29th. That morning, the wind drops right out – glassy conditions, which is a gift. The swell is a solid 8ft from the ENE, with a moderate 10-second period. The energy is pumping, clocking in at 1630, so there’s real power in the water. That said, 8ft is pushing into expert territory, so this is not for the faint of heart. The swell direction is coming from the ENE, which is a bit off the optimum NNE for this spot, but those glassy conditions will make it clean. Expect a few sets that’ll make your heart pound.
After that brief window, the wind swings back onshore or cross-shore for the rest of the run. The surf quality drops off a cliff. You’ll see some size, but it’s all lumpy, messy, and cross-onshore. The combined energy dips into the 400s and 300s by late July and early August, which is weak. The period drops to 7-8 seconds, meaning short, weak, wind-affected waves.
There’s a slight glimmer on Sunday, August 9th, with a light cross-off breeze and a clean surface, but the swell is only 4ft, with a period of 7 seconds and energy of just 146. It’s surfable, but ordinary. Not worth getting excited about for a trip.
So, bottom line: if you’re an experienced surfer, mark your calendar for Wednesday, July 29th morning. Get out there early for the glass. Otherwise, the rest of the outlook is a write-off. The trade winds just won’t quit.
Rusty.
