The Lowdown
Rusty here. Let's break down what's going on with Rabbit/Manana Island. Honestly, the outlook is pretty grim for the next couple of weeks. Ocean temp is pretty standard for the season.
From Tuesday, August 25th, all the way through Sunday, September 6th – that's a solid 12 days – the window is shut. Strong cross-shore and cross-onshore winds at 18 to 25 mph will be tearing up the surface. The swell runs mostly between 4 and 6 ft from the E or ENE, but it's just a messy, lumpy ocean the whole time. Wave energy is weak to moderate in that stretch, with values ranging from 142 to 387 – nothing that’ll turn your head even with a clean breeze. There is zero surfable conditions in that whole block.
The one ray of light is Monday, September 7th. For the morning session, the wind swings light and offshore out of the ESE at just 6 mph. The swell holds at 6 ft from the ENE with a period of 7 seconds. That offshore flow will clean things up nicely. The combined energy hits 394, so there’s enough push to work with. It’s the only morning in the whole 16-day outlook that offers anything close to good waves. Expect short-period stuff, so a bit choppy on the face, but rideable. By Monday afternoon, though, the wind goes back onshore, and the rest of the week slips back into the same old lumpy conditions.
Bottom line: pencil in that Monday morning, September 7th, if you want a shot. The rest is a total loss. This stretch is more suited to kite-surfing than paddling out, especially given that beach setup.
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.
