The Lowdown
Alright folks, Rusty here. Let’s talk about what’s coming up for Rabbit/Manana Island. We’ve got a 16-day window with some action, but there are definitely swells we’d rather skip.
Overall, the pattern kicks off with some energy, but the wind is the main player, and it’s not being friendly. The first real hope for a wave is on Sunday the 6th, but the conditions are rough – a 7 ft swell from the ENE with an 19 mph cross-breeze and lumpy chop. The water temp is sitting right on 81°, which is bang on average for September, so nothing weird there, but the ride won't be pretty.
The standout of the whole window lands on Tuesday afternoon, the 8th. That’s the one to circle. We get a clean 6 ft from the ENE with a solid 11-second period and a nice offshore breeze out of the south. The combined energy is moderate (778), and the forecast says expect very good surf conditions. For Rabbit/Manana Island exposed to the NNE, this ENE swell will wrap in nicely. Crowds can be a thing here sometimes, but with this quality, it’ll be worth sharing the water.
After that, it’s a rough stretch. A lot of messy, lumpy days with short period windswell and onshore slop. Wednesday the 9th sees size drop to 4 ft, and from Thursday through to mid-next week it’s mostly junk – 3 ft to 6 ft but with short periods of 6 to 8 seconds and lumpy cross-shore winds. Not worth paddling out for.
The next flicker of hope holds for Sunday the 20th. We get a glassy morning with a 4 ft swell from the east, 8-second period and 241 combined energy. Clean to start the day, and the wind flips light offshore by Monday morning the 21st. That Monday session with a 4 ft east swell, 9-second period, and glassy conditions will be a nice reset if you’ve been waiting.
So, to break it down: Tuesday the 8th afternoon is the best on offer, with a clean offshore and decent groundswell. Monday the 21st morning is your backup glassy day. The rest is a waiting game.
Rusty.
