The Lowdown
Well, folks, it’s Rusty here, and I gotta level with you. Looking at the next 16 days for our stretch of coast, this is one of those stretches where you might wanna double-check your board wax and just wait for a window, because right now, the ocean’s just not playing ball. The standout spot, Rabbit/Manana Island, is breaking, sure, but every single window in this outlook is rated as poor surf. It’s a pretty grim picture, a real flat and choppy stretch.
The wave energy never really gets going, mostly sitting in that weak to moderate range. We’re seeing the combined energy values in the low to mid hundreds, like around 489 at the start, but it quickly fades. Even when the swell source looks okay, the wind is the killer. All week, it’s onshore or cross-shore, which is just chasing everything out and leaving it lumpy and messy. The water's warm, about 80.6°, which is pretty much average for this time of year, so at least you won't need a hood.
We start the period this Wednesday, the 9th, with a bit of a tease. There's a clean-looking morning with a light cross-on breeze, but the surf is only around 3.9ft with a short, 9-second period. It’s the only morning that isn't totally written off, but it’s still a “marginal” call. That’s the best it gets, and it’s not saying much.
From Wednesday afternoon, it just goes downhill. Thursday the 10th brings a bump of swell—pushing up to 5.9ft—but the wind is fresh and onshore, making it a complete washout. The period drops to a junky 7 seconds, and it's cross-chop central. It’s not even worth paddling out for that one.
The whole first week is a write-off. We got a solid seven to eight day stretch here with nothing but onshore wind, chop, and poor surf. Wednesday through to the following Tuesday, the swell is there at times, around the 3ft mark, but it’s constantly being battered by 15-20 mph winds. A couple of afternoons have a longer period swell, like the 11-second one on Friday, but it’s still messy. The energy just fizzles out by mid-week, dropping down to weak readings in the low hundreds.
Looking further out, and I mean a week and a half away, there’s a sniff of something bigger. Around the 17th and 18th of September, Thursday and Friday, the models are showing a push of swell back up to 4.6ft to 5.2ft. But, and it’s a big but, the wind is forecast to be blowing a fresh 20 to 22 mph from the east-northeast. That’s not going to give us the clean lines we want. The period is still short—around 8 seconds—so it’s going to be a bumpy, lumpy mess. The energy does climb back up to moderate levels then, but with wind like that, it's going to be a battle.
There are some promising long-period glassy conditions after that, but they're just not aligning with any decent swell. The whole window is honestly looking more like a kitesurfer's forecast than a surfer's. With that constant cross-shore wind and the size of the swell, there’s gonna be a lot of chop and bump for them to play in, but for us paddle surfers? Not so much.
If you're desperate, that Wednesday morning is your only real chance, and even then, you're just getting wet. But look, the spot is fairly consistent, so it tends not to stay this bad for long. Forecasts can change. My advice? Keep an eye on the charts, and I’ll see you out there when it cleans up.

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.
