The Lowdown

Alright, Rusty here again. Let’s break it down in the old measures.

Truth is, it’s a rough outlook for Rabbit/Manana Island. A long, frustrating stretch of poor surf with onshore wind that just won’t quit.

From August 28th through September 10th, it’s a mess. Winds are fresh to strong from the east-northeast, 20 to 25 mph, gusting to 28 mph, creating lumpy, choppy, cross-onshore junk. Swell heights run from 5 ft to 7 ft, sometimes 8 ft, but the wind chops it all to pieces. Wave periods are short—6 to 8 seconds—so the energy is weak to moderate. Water temp is about 81°F, normal for the season.

The one bright spot comes on Friday, September 11th, in the morning. The wind finally switches to a light cross-offshore from the southwest at 6 mph, and the ocean cleans up. Swell is 7 ft from the ENE with a 8-second period, and the energy is moderate. The break is consistent, but watch for crowds. That morning is your best chance. The next morning, Saturday, September 12th, also has a light cross-offshore breeze and a 5 ft swell, but it’s smaller and more marginal.

The rest of the forecast stays windy and messy. Don’t hold your breath for the first two weeks. That Friday, September 11th session is the only one worth paddling out for.

Rusty.

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.
