The Lowdown
Hey, Rusty here again. Let’s break down the surf for this spot.
We’ve only got Rabbit/Manana Island to look at for the whole 16 days, and it’s mostly a rough spell. The water temp is 80°F, right around average. The first bit of the forecast is the only time it even gets close to okay.
Wednesday, July 29th morning is your best bet. Clear skies, an offshore wind at 9 mph from the north, and you’ve got 7 ft of ENE swell with a 10-second period. The combined swell energy is moderate at 733. The offshore wind will make it clean for a few hours, but it’s still only marginal. By afternoon the wind turns cross-on, so catch it early.
Then the bottom drops out. From Thursday, July 30th right through to Wednesday, August 13th, it’s a grind. The wind from the ENE picks up, going cross or cross-on, and hits 31 mph by Saturday, August 1st with a near gale. That day has 8 ft of swell but it’s completely blown out and messy, with very strong energy (1098). All the good stuff is ruined by the wind.
There’s a little chance on Tuesday, August 4th morning. Still cross-on, but you get a 5 ft ENE swell with a longer 12-second period and 671 energy. That longer period means better shaped waves, but the cross-on wind makes it choppy. Only for the keen.
The second week is a waste. From August 5th on, swell heights drop to 3 ft to 5 ft, periods fall to 6-8 seconds, and the energy is low to moderate (134 to 358). It’s all poor, lumpy, and cross-chop. No glassy conditions to be found. If you’re desperate, Wednesday morning July 29th is the only window worth paddling out for.
Rusty, out.

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.
