The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Alright, so we’ve got Ambinanibe to look at, and the first solid window is going to be a bit of a wait. The opening days are a write-off – Wednesday and Thursday are messy with wind and swell that just doesn’t line up right. Thursday afternoon does see a 10-foot bump from the SSE, but with a 10-second period and cross-onshore wind, it’s just a big, lumpy mess. Not for paddling.
Friday the 14th morning is where we finally get a real look. The wind swings light WNW, going clean and cross-offshore, with a 8-foot swell from the SSE at 10 seconds. The combined energy is moderate (1253), and the water temp is around 73°, which is bang on average for this time of year – no surprises there. This is the best of the first week. It’s a solid, clean combo for experienced surfers.
Saturday the 15th has a big groundswell pulse from the SSW, 7 feet at 18 seconds – that’s a very long period. The combined energy is strong (3352). The morning is clean with a cross-offshore breeze, but a 20 km/h wind is a bit firm. That long period will make it a bit walled and straight on a beach break, but if you find a corner or a point, it’ll be a freight train. Not for the faint-hearted.
After that, the swell backs right off into the middle of the week. From Sunday the 16th through to Thursday the 20th, it’s pretty quiet. Waves drop below 3 feet mostly, with periods getting long but no real power. The 20th morning goes glassy, but with only 2 feet on offer, it’s a tiny, clean little wave. Good for a longboard if you’re desperate.
Now, look ahead to Friday the 21st morning. This is a standout. A 6-foot S swell at 14 seconds, glassy conditions, and the combined energy is a massive 2968. That’s proper groundswell energy, and with zero wind, it’s gonna be smooth, clean, and powerful. This is the pick of the period for experienced surfers.
Then Sunday the 23rd morning is another one to circle. A 7-foot SSW swell with a 17-second period, clean cross-offshore light breeze, and a combined energy of 3221. That’s a very strong, very long period groundswell. It’s going to be a proper session for the crew that knows the line-up.
The very end of the run, Tuesday the 25th morning, is just huge – 10 feet from the S at 15 seconds. That’s a big, powerful swell. The combined energy is 3476, the strongest in the whole window. But the wind is cross-shore and fresh at 30 km/h, so it’s going to be wild and lumpy. Only for the hardcore, and even then, it’s a beast.
So, the short version: The first week is a slow start with Friday the 14th morning being the best. The real fire comes in the second week – Friday the 21st morning is the standout for clean, powerful lines, and Sunday the 23rd morning is right there with it. Mark those dates.
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.
