The Lowdown

Alright my friends, Rusty here. Let’s hash this out for the next 16 days at Rabbit/Manana Island. I’ll level with you, the outlook is a bummer. The books are saying there’s no good surf on the cards.

Starting off on Thursday afternoon, August 6th, we’ve got a tiny 1 foot swell from the ENE, only 6 seconds between waves. The wind is blowing 19 mph from the ENE, cross-on, making it a lumpy mess. The combined energy is a weak 108. Water temp is 80°, right where it should be for the season.

And that’s the story, day after day. Through Friday, Saturday, Sunday, and all the way into the next week, the swell creeps up, hitting 5 feet on Saturday morning, but the wind stays stuck on your shoulder from the ENE, 19 to 22 mph. The periods are short, 5 to 8 seconds, so the waves are just weak and choppy. The energy grows, getting up to 309 by Sunday morning, but it’s all wind-slop.

Come the second week, around August 15th and 16th, the swell gets bigger, pushing 7 feet, and the energy climbs into the 400s and 600s. But the wind is up to 28 mph, still cross-on and messy. That’s a lot of water moving, but it’s going to be a blown-out, choppy mess. For a beach spot like this, you’d be better off rigging a kite than waxing a board.

The last few days, from August 17th to the 21st, the swell sticks around 5 to 7 feet, but the wind doesn’t ease up. Always cross-on, always fresh, periods short. There is no clean window, no glassy morning, no offshore breeze to save the day. It’s a solid run of poor surf. The spot is fairly consistent, so it’s not always this grim, but for this forecast, there’s nothing to get excited about.

Rusty, out.

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.
