The Lowdown
G’day, Rusty here. Look, I’m not gonna sugarcoat it – this is a rough run for Rabbit/Manana Island. We’ve got a 16-day window here, and honestly, there’s barely a session worth paddling out for. The first few days are a write-off, so don’t bother waxing up just yet.
We finally see a tiny glimmer on Tuesday the 8th. Tuesday morning is marginal, but by Tuesday afternoon it cleans right up. The wind swings offshore from the south at 12 mph, making for some clean, workable faces. Swell is from the ENE at 6 ft, with a period of 11 seconds – that’s decent groundswell energy, giving the waves some shape and punch. The combined energy sits at a moderate 820. Water temp is about 81°, pretty much normal for this time of year. This is your best shot in the whole forecast, but it’s not a standout classic – just the least ugly day on the calendar.
After that, it goes back to rubbish. From Wednesday the 9th afternoon right through to the end of the 16 days, it’s all poor conditions. Strong cross-shore and cross-onshore winds, lumpy chop, and messy swell. Swell sizes bounce between 5 ft and 7 ft, but with short periods (mostly 7–8 seconds) and dirty winds, it’s just not surfable. The combined energy dips into the low hundreds at times, weak and unappealing.
There’s a lot of ENE wind, right on the nose of that optimum NNE direction this spot likes. So even when there’s swell, the wind and direction are fighting it. This stretch is more suited to kite surfing than paddle surfing – the wind is strong and consistent, and the surf quality is just not there.
Bottom line: if you’re keen, try Tuesday afternoon the 8th. It’s clean, manageable, and your only real option. The rest? Save your energy. Forecasts can change, but right now, it’s a lean run.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Rabbit/Manana Island may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
