The Lowdown
Alright folks, Rusty here. Gotta be straight with you, the outlook for Rabbit/Manana Island is a bit of a rough patch for a while. The onshore winds have a firm grip on things and aren't letting go easily.
For the next ten days or so, from Saturday the 22nd right through to the end of August, it’s pretty grim. The wind is hammering in from the ENE and NE at 18 to 28 mph, with a lot of cross and cross-on conditions. There's swell on the table, mostly between 5 ft and 7 ft, but it's coming with a short, weak 6 to 8-second period and combined energy figures mostly in the 200-700 range (moderate to strong energy), but it’s all ruined by the wind. The wave comment says "poor surf conditions" nearly every day, and that's exactly what it looks like – lumpy, choppy, messy.
Things stay poor right into the first few days of September. On Tuesday the 1st, we finally see a shift in wind direction to NNE at 15 mph, going onshore, but the swell is still messy with a 5 ft ENE swell and a 10-second period, giving moderate energy (470). It's still not great.
The first real flicker of hope comes on Wednesday the 2nd of September. The morning has a light N wind at 6 mph blowing onshore, with a 5 ft NE swell at 9 seconds (energy at 307 – moderate). But the standout is the afternoon. Glassy conditions with zero wind, and a 5 ft swell from the ENE at 8 seconds. The wave comment says "expect good surf conditions" and it's got a score that finally makes you look twice. It's not a massive swell, but that clean, glassy surface will make all the difference. This is the best on offer across the whole 16-day window.
Thursday the 3rd sees the wind swing back around to the east at 6 mph in the morning, giving some cross-shore action with a 6 ft ENE swell (7 seconds, energy 331). It's marginal though, and by the afternoon it's back to cross-onshore choppiness. The end of the outlook into the first week of September stays poor or marginal, with more ENE winds and messy cross-shore conditions.
So, if you're desperate for a paddle, keep your eyes on Wednesday afternoon the 2nd of September. That glassy session is your one true stand-out in an otherwise windy fortnight.

A general guide to surfing at Rabbit/Manana Island can be found by selecting the local surf guide option on the grey menu.

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.
