The Lowdown
Alright folks, Rusty here. Gotta be straight with you – it’s a tough stretch ahead for the Rabbit/Manana Island zone. We’re looking at a real flat spell with nothing that’s really worth paddling out for.
The whole 16-day window is a write-off for decent surf. There’s going to be swell in the water, but it’s all junk. From now right through to the end of the forecast on September 10th, every single session is labelled "poor surf conditions". The wind is a major problem – it’s howling from the ENE, mostly cross or cross-onshore, with speeds between 15 mph and 25 mph. That’s a fresh to strong breeze, turning the ocean into lumpy, messy, cross-chop. It’s not surfable.
The swell energy is the only thing that changes, but it’s useless. Early on, from August 26th to 30th, the combined energy sits around 170 to 330 (moderate), but the swell period is a weak 6-7 seconds. That’s just wind-chop, not a wave you can ride. It picks up a bit more energy from September 1st to 4th, hitting the 400s and even 690 (moderate), but the period only crawls up to 8 seconds. Still short, still messy, and the wind hasn’t let up. Even the water temp is a non-issue – at 81°F with a tiny anomaly of 0.5°F, it’s just what you’d expect for this time of year. Doesn’t matter when the waves are a write-off.
The only thing that gets close to a "marginal" call is September 5th morning and September 6th morning. We get a jump in period to 11 seconds on the 5th (a proper groundswell) and a combined energy of 531 (moderate), and on the 6th the energy is 551 (moderate). But the wind is still cross or cross-onshore at 12-15 mph. It’s a cross-chop mess. The break is exposed to the NNE, and the swell is coming from the E and ENE, which isn’t the optimum direction. It’s not good enough to recommend.
This is one of those blank runs, folks. Unless you’re desperate for a messy paddle, save your energy. The forecasts can change, but right now, there’s nothing to get excited about.
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.
