The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s in store for Ambinanibe over the next couple of weeks.
The outlook starts off slow, but there’s a real standout window coming up that’s going to get the blood pumping. The water is sitting at 74°, which is about average for this time of year, so nothing to write home about there.
The first few days are a write-off. Sunday the 9th through Monday the 10th are plagued by moderate to fresh cross-off and cross winds, with marginal surf quality and poor conditions. The swell is hanging around 4ft from the SSW with a moderate energy, but the wind just won’t play ball. Not worth paddling out.
Then Tuesday the 11th morning is where it starts to get interesting. The wind drops to glassy, with a light NNW breeze, and the swell is 4ft from the SSW, period 14 seconds, with moderate energy. This is a proper window of clean, glassy conditions that will make the most of that groundswell. The break is consistent and exposed, so expect some fun, well-shaped waves. This is the best on offer in the first week – get out there.
The middle of the week falls apart again. Wednesday the 12th and Thursday the 13th bring onshore winds, rain, and building swell that gets messy and lumpy. By Friday the 14th, the swell pushes up to 8ft from the S, but the wind is moderate cross-off and the surf is only marginal. This is getting big, and the quality isn’t matching the size.
Now, the real standout. Saturday the 15th morning is the highlight of the entire forecast. The swell is 7ft from the S, with a very long period of 17 seconds, and the combined energy is massive. The wind is light and cross-off, keeping it clean. This is powerful, long-period groundswell that will be best handled by experienced surfers – it’s too big for beginners. The break is consistent, and with that clean wind, the waves will be lined up and punchy. Absolutely the pick of the forecast.
After that, the swell slowly drops off through Sunday the 16th and into the following week, with cleaner conditions but smaller, weaker waves. By Tuesday the 19th, we’re looking at tiny 1ft to 2ft swell with minimal energy, and the last few days of the forecast go flat and messy. The 23rd and 24th of August see a huge pulse of 10ft to 12ft from the SSW, but it’s flagged as too big for this break, with strong cross-off winds. That’s a pass for paddle surfing, unless you’re a masochist.
So, the solid takeaway: Tuesday the 11th morning for a clean, glassy session, and Saturday the 15th morning for the big, powerful groundswell that will have the experienced crew grinning.
Rusty.

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.
