The Lowdown
Alright, Rusty here again, but in feet and miles. Ambinanibe is a consistent break for intermediates, exposed to the open ocean, with water temp around 73°F — right on the average for this time of year.
The first action comes Saturday the 15th with a 5ft SSW groundswell carrying a very long 17-second period. The swell energy is strong at 2110, but we’ve got a fresh 19 mph cross-shore wind chopping it up. Power is there, but the surface isn’t pretty.
Sunday the 16th morning offers a clean 4ft S swell with 14 seconds under a moderate 12 mph cross-offshore breeze. It’s clean but small. Then we wait. The real gem shows up Friday the 21st morning. It’s glassy—almost no wind—with a clean 4ft SSW groundswell and 14 seconds. Energy is a solid 607, and the conditions are perfect. That’s the one.
Saturday the 22nd keeps the 5ft SSW swell in the morning, but the afternoon bumps to 7ft at 13 seconds with lumpy wind. Sunday the 23rd morning sees a huge 10ft S swell with a 15-second period and light offshore winds. Over 8ft, that’s expert territory only. Monday the 24th is still a heavy 7ft, and by Tuesday the 25th, we’re looking at a massive 13ft S swell with a 17-second period—energy reading skyrockets to 9002 (very strong). That’s too big for normal paddle surfing; kite surfers will be having a field day.
The standout is clear: Friday, August 21st, early morning. That glassy, clean, proper groundswell window is your best bet for the whole two weeks.
Rusty.

Information about the Ambinanibe Surf forecast
The above surf forecast table for Ambinanibe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ambinanibe can be found by selecting the local surf guide option on the grey menu. Our Ambinanibe 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 (Ambinanibe) 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 Ambinanibe 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.
