The Lowdown

Alright, let’s look at it in feet and miles per hour. This is a rough one.

We’re looking at Rabbit/Manana Island, and the water temp is around 81°F – totally normal for this time of year. But that’s where the good news ends.

From August 29th, it’s a nightmare. The wind is blowing cross-onshore from the ENE at 25 mph, and the swell is about 6 ft with a short 6-second period. Wave energy is moderate, around 300 (combined energy), but it’s all wind-chop and messy. This junk continues day after day, with the swell size hovering between 6 ft and 6 ft, and the wind staying fresh and cross-onshore. No reason to get wet.

On September 4th, the morning shows a 6 ft swell from the ENE with a long 13-second period and energy jumping to 1215 – that’s a real groundswell. But the wind is still a fresh cross-onshore from the NE at 19 mph. The surface is lumpy and poor. It’s a waste of good energy. The swell builds through the 5th and 6th, hitting over 8 ft on the 6th with a 10-second period and energy screaming up to 3156. That’s a lot of power, but with the wind howling cross-onshore at 28 mph, and the swell coming from the ENE when the spot wants it from NNE, it’s just a mess. At that size and with those winds, this is really only any good for kitesurfers.

The second week sees the size drop. By September 13th, the swell is down to about 3 ft early, and the wind finally goes light. In the afternoon, we get a 3 ft swell from the NNE, a light cross-offshore breeze, and energy down to 166. It’s clean, but the waves are tiny – marginal at best. It’s the only session in the whole 16 days that might be worth a look, but it’s not a standout, it’s just not terrible.

There’s no real winner here. The break is fairly consistent, but the conditions just aren’t cooperating. Save your energy for another time.

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.
