The Lowdown
Alright, this is a tough one to call. To be honest with you, for the next sixteen days, the outlook for Rabbit/Manana Island is pretty grim. There’s not a single day in the forecast that offers a proper surf session. The wind is just relentless from the east-northeast, and it's almost always cross or cross-onshore, which is going to leave that water looking like a washing machine. You’ll be fighting a lumpy, choppy mess, not riding clean waves.
The swell sticks to a short-period, wind-driven ENE pulse, mostly around 6 to 8 seconds, so there’s no real power or shape to it. The combined energy climbs from a weak 210 (moderate wave energy) early on Thursday, August 6th, up to a very strong 856 by Monday, August 17th, but that energy is completely wasted by the wind. It’s just a big, blown-out, messy ocean. For a spot that’s exposed to the NNE, this constant ENE wind is just a killer.
The water temperature anomaly is average for this time of year, so nothing unusual there, but you won’t care about the temp when you’re getting blown sideways.
There’s a very brief moment on Friday, August 21st, the very last day of the forecast, where the wind finally swings around to the north at a light 6 mph, becoming offshore. The swell is still just 5 ft from the NE with a 9-second period, and the combined energy is a moderate 325. It’s the only time the wind is right, but the swell is nothing special. It’s a glimmer of hope, but it’s a long way off and the rest of the fortnight is a write-off. For a spot that’s fairly consistent, this is a painfully long run of poor conditions.
Let’s be real, with this much wind and a messy cross-chop, this setup looks more interesting for a kite surfer than a paddle surfer right now.

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.
