The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this is one of those outlooks where you might want to take up a different hobby for a while. The whole 16-day window is a tough slog for Rabbit/Manana Island. The wind is a constant enemy, hammering in from the ENE and NE most days, making a mess of things. It’s almost all cross-onshore or cross-shore, and the wave quality suffers big time. There’s a significant gap right at the start: from Thursday the 27th of August all the way through to the 10th of September, the surf is just poor. Day after day of lumpy, choppy, messy conditions. You’ll see some size, but it’s ugly.
The only real glimmer in this whole forecast comes right at the very end. On the morning of Friday, the 11th of September, something finally shifts. We get a light breeze coming from the SE, turning offshore for this spot, and the forecast is for “clean” conditions. The swell is around 4.6ft from the east, with a decent period of 11 seconds pushing through. The combined energy is strong, hitting 707. The water temp is sitting at a normal 80.8°F for this time of year. This is the standout session in the whole outlook – that offshore wind is the key, promising some proper clean surf.
The afternoon of the 11th, though, the wind swings back around to a moderate cross-onshore ENE breeze at 15.5 mph and the quality drops right off again. So there you have it – a long, dry spell, and one brief, promising window. Fingers crossed that morning holds up.
