Table - best surf conditions forecast for Rabbit/Manana Island over the next 16 days.
Alright, this is Rusty. Let’s not sugarcoat it – it’s looking pretty bleak for Rabbit/Manana Island for a while.
Through most of this period, we’re stuck with a strong ENE wind that’s predominantly cross-onshore, shredding any chance of clean waves. Swell height sits between 6ft and 8ft, but with that wind, it just turns the ocean into a lumpy, choppy mess. Wave energy is moderate, ranging from about 260 to 688, but none of it is surfable. The water’s sitting at a warm 79°, which is about normal for this time of year.
You’re looking at a dead run from the 7th all the way through the morning of the 21st of July. It’s just day after day of messy conditions. There’s a slight break on the morning of the 18th with cross-shore winds, but it’s still only a ‘marginal’ call.
Now, the light at the end of the tunnel. On the morning of Tuesday the 22nd, the wind shifts to a light E, going cross-offshore, with a 3ft E swell carrying a very long 15-second period. That’s real groundswell energy, and the combined energy is a strong 696. It’s a long way out, but that’s the best we’ve got.
Then the afternoon of the 22nd might be the gem. The wind goes glassy, almost calm from the SSE. You’ll get a clean 3ft E swell with a 14-second period. The energy’s still solid at 612, and with glassy conditions, those waves will be smooth and lined up. That’s the day to circle.
Bottom line: the first two weeks are a washout. But hang in there for the 22nd – it could offer some clean, glassy surf, especially for the reefs and points.
Rusty.

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.
