The Lowdown
Alright folks, Rusty here. Let's slice into this forecast for Rabbit/Manana Island. I gotta be straight with you – this is a tough stretch. We’re looking at sixteen days of onshore and cross-shore winds that just won't quit, making a mess of what little swell we've got. There’s no standout, no day to circle on the calendar. The whole window is a blank run.
It kicks off Thursday, September 10th and it's already grim. A 5ft east-northeast windswell at a short, weak 7 seconds, but with a 12 mph cross breeze, the surface is chopped and lumpy. Swell energy is moderate (385). The afternoon only gets worse as the wind ramps up to 22 mph, turning it cross-onshore. Just ugly.
Friday through the weekend, September 11th to 13th, is more of the same. Swell drops to around 3ft, periods are short – 7 to 11 seconds – and the cross-onshore or cross winds keep things bumpy. Clean lines? Forget it.
The whole second week, from the 14th into the 23rd, the swell stays anemic (2ft to 4ft) with periods rarely over 10 seconds. You'll see moderate wave energy in the 100 to 300 range. Winds stay from ENE at 9 to 25 mph, always cross or cross-onshore. There's a few days, like the 21st and 22nd, that tip into "marginal" territory with lighter winds at 6 mph, but it's still a cross breeze with a risk of thunderstorms, so your chances of a clean window are slim.
By the last day on the 25th, we get a bit of size back – 5ft from the ENE at 8 seconds – but the wind is a fresh 22 mph. It’s just messy. The combined energy jumps to 416, but with that wind, it's not surfable, it's just a washing machine. This setup, with significant swell and constant poor quality, honestly looks better for kite surfing than paddle surfing right now.
There’s nothing here that’s worth paddling out for. Sometimes the area just goes quiet like this, and this is one of those times. Keep the board in the bag, and let’s hope the next forecast brings better news.
