The Lowdown
Alright, listen up. Let's talk about Rabbit/Manana Island. I'm not gonna sugarcoat it – the next 16 days are a real rough stretch. The wind is the main problem, blowing from the ENE for days on end. That's a cross-onshore breeze for this spot, and it's gonna make everything lumpy, choppy, and ugly.
The first few days are a write-off. From Thursday the 3rd through Saturday the 5th, there's a solid 7ft to 8ft ENE swell, with moderate to strong wave energy, but it's getting blasted by a strong wind. No good.
We get a tiny glimmer of hope on Monday the 7th afternoon. The forecast says the swell will be too big for the break at 13ft, but the wind goes light and clean. A pass for paddle surfing. Then Tuesday the 8th, the swell drops and the wind goes offshore from the SSW, giving us a clean 4ft to 5ft, but the wave energy is weak and the forecast is marginal. Not really worth it.
Now, the one true standout is Wednesday the 9th morning. The wind goes glassy, dead calm, and the swell drops to a tiny 2ft from the East. This is a long-period groundswell (14 seconds), so it'll have some shape. For a break that's exposed to NNE, the swell is coming from the east, which is a bit off, but with glassy conditions, it's the best we're gonna get. It'll be small and clean, perfect for a log or a fish. The water temp is about normal for this time of year.
After that, it's back to the grind. From the 10th through the 13th, the wind is back on it, with messy conditions. The swell holds around 6ft to 8ft, but the quality is poor. Then from the 14th to the 18th, it gets huge. On Monday the 14th it's 12ft, and by Tuesday the 15th it's a massive 15ft with very strong wave energy. This is way too big for Rabbit/Manana Island, and the wind is still messy, making it a total soup. This looks more like a kite surfing zone than a paddle surf spot.
So, the only real chance to get out is Wednesday the 9th morning. Get out there early for the glassy, clean, small waves. The rest of the run is either blown out or too big. Hang tight and keep an eye on the forecast.
