Ambinanibe Surf Forecast and Surf Report

Alright, grab a coffee, let's talk about Ambinanibe. Water’s sitting at about 73°F, pretty much normal for the season.

We start slow on Sunday the 30th of August. A south swell of about 5ft with a 12-second period, combined energy around 600 (moderate). Wind is northeast at 15 mph, cross-off, so it’s clean. But it’s just a marginal session. Monday the 31st drops way off to 3ft from the SSE, energy down to 173 (weak). Light NNE wind keeps it clean, but the waves are ordinary. Tuesday the 1st is tiny – 1ft from the SSE, and a glassy morning that’s barely worth a paddle. Wednesday the 2nd afternoon is a mess: a 7ft short-period east-northeast windswell (6 seconds) rolls in with a fresh cross-shore wind. Lumpy and horrible.

A few quiet, poor days follow until Friday the 4th of September. That morning we get a 5ft south-southwest groundswell with a nice 14-second period, energy of 911 (moderate). The wind is a clean cross-off, but the call is only marginal. Saturday the 5th morning is the first decent window: 4ft south-southwest, 13-second period, light northeast wind, energy 378 (moderate). It’s clean, and the report says “expect good surf conditions.”

Now, the big one. Monday the 7th of September: a massive 10ft south swell with a very long 16-second period. Combined energy hits a whopping 6173 (strong to very strong). Wind is cross-shore and clean, but the forecast says it’s predicted to be too big for this break. That’s for experts only. Afternoon is the same story – 10ft, 15 seconds, 4263 energy. Too heavy.

The real standout for the experienced crew is Tuesday the 8th of September morning. The swell drops to a still-serious 7ft from the south, 13-second period, energy at 2098 (strong), with a light cross-off breeze making it clean. That gets the highest rating and is described as excellent conditions for experienced surfers. That’s your best day of the whole 16-day run.

After that, it settles. Wednesday the 9th has a clean 4ft south-southeast groundswell, period 11 seconds, light offshore air. Very good session. Thursday the 10th is similar: 4ft south swell, a long 16-second interval, clean cross-off. Solid.

From Saturday the 12th through Monday the 14th, the wind turns onshore, the swell fades to poor, lumpy conditions. The last day, Monday the 14th afternoon, throws up a 6ft south-southwest swell with a short 10-second period and a fresh cross-shore wind – a messy end.

So the call is simple: the absolute best is Tuesday morning, 8th of September, for the experienced surfers – a powerful 7ft south swell, clean. For the rest, the best real option is Wednesday morning, 9th of September, with a clean 4ft south-southeast swell. Get on it.
