The Lowdown
Alright, this is Rusty. Let’s be real about Rabbit/Manana Island – the next week and a half is mostly a write-off. We’ve got a long stretch of poor conditions starting now and running deep into September. The wind is howling from the ENE almost constantly, cross-on or cross, with speeds up to 28 mph, tearing the place up. It’s messy, lumpy, and not worth your time.
First sign of life doesn’t show up until the morning of September 8th. That Tuesday morning, the wind swings around to a gentle offshore from the south at just 9 mph. The swell drops to 5 ft from the NE, period around 9 seconds – not huge, but clean. The combined wave energy is a moderate (516). That’s the standout window. It’ll be clean and rideable, decent for intermediates. Crowds are possible here sometimes, so get out early. The water temperature is sitting around 80°, pretty average for this time of year.
Tuesday afternoon on the 8th keeps it clean with a light SSW breeze, but the swell drops to 5 ft from the east and the period shortens to 6 seconds – less power, but still a window.
After that, we’re back into the wind and chop. There’s a tiny possibility on the morning of September 12th with 4 ft from the ENE, but the cross wind and period of 8 seconds keep it marginal at best. From there it fades right down to under 3 ft through mid-September, with more onshore wind.
Overall, the only real shot you’ve got is the morning of September 8th. Everything else is blown out or weak. Keep an eye on the forecasts, because when it’s on, it’s on, but this run is rough.
Rusty.

Information about the Rabbit/Manana Island Surf forecast
The above surf forecast table for Rabbit/Manana Island provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rabbit/Manana Island can be found by selecting the local surf guide option on the grey menu. Our Rabbit/Manana Island surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Rabbit/Manana Island) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
