The Lowdown
Alright, Rusty here. Let’s break down the Rabbit/Manana Island zone.
It’s a slow start. Monday afternoon is a total washout with a stormy 2.5m and a 35 km/h cross-off wind. The water is 81°F, which is about normal for now, so nothing weird there.
The one real highlight is Tuesday morning, September 8th. We’ve got a clean 6ft groundswell out of the ENE, with an 11-second period, and the wind is offshore from the SSW at 19 mph. That’s the ticket. The combined energy is 884 (moderate wave energy), and the swell direction lines up well with the optimum NNE exposure. The afternoon is still rideable at 6ft, but the wind goes cross-off, so morning is the better call.
After that, it’s a long dry spell. From Wednesday the 9th all the way through to the 16th, the swell drops and the wind is mostly onshore or cross-shore. Nothing over 4ft, short periods, and the energy is weak. It’s not worth paddling out.
Then, in the second week, things shift. On Thursday morning, September 17th, a new NNW groundswell shows up with a 13-second period and 2ft. The wind is light and cross-off, so it’s clean. The energy is low at 246, but it’s surfable. Friday morning the 18th is similar with 4ft and a 12-second period, also clean. The real sleeper is Tuesday morning, September 22nd. The wind goes glassy, the swell is 3ft from the NNW with a 10-second period, and the energy is 235. That’s a classic dawn patrol.
So, bottom line: Tuesday morning, September 8th is your best bet. After that, wait for the 17th, and keep an eye on the 22nd for a glassy, clean session. Everything else is a waiting game.
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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
