The Lowdown
Alright, pull up a seat. Rusty here, and I’ve gotta be straight with you about this stretch ahead. We’re looking at a pretty grim run for Rabbit/Manana Island for the next couple of weeks, so don’t be holding your breath.
What we’ve got is a classic case of a spot that’s exposed to the swell, but it's getting hammered by onshore and cross-shore winds that just won’t let up. The water temp is sittin’ around 80°F, which feels normal for this time of year.
The whole 16-day window is basically a write-off for clean, ridable waves. We start off on Wednesday the 5th of August with weak, short-period swell from the ENE around 4ft to 4ft, but it’s wrapped in a moderate cross-onshore breeze, making for choppy, poor conditions. This trend holds through the first week. The swell energy is weak to moderate, rarely cracking triple digits (277) early on, but the wind is the real killer – just a constant grind of fresh to strong breezes from the ENE or NE, keeping the surface lumpy and messy.
As we roll into the second week, the swell actually starts to build. By Sunday the 16th of August, we’re seeing head-high, 7ft ENE swell with moderate energy (520), and it keeps climbing, hitting 8ft with strong energy (651) by Monday the 17th. The period stretches out to 8 seconds later on, which gives the waves a bit more shape, but the wind remains a stubborn cross-onshore at 22-28 mph. With waves over 8ft and messy, windy conditions, this is strictly for the experts – and even then, it’s more of a battle than a session. Honestly, with this consistent cross-onshore wind and a beach setup, this stretch looks way more interesting for kite surfing than paddle surfing.
I can’t point to a single standout here. There isn’t one. We’re looking at a solid two-week gap with nothing worth paddling out for. That’s unusual for an exposed spot like this, but when the trades set in, they set in hard. Forecasts can change, but right now, it’s a big *pass*.
Rusty.
