The Lowdown
Alright, Rusty here. Let’s break down Ambinanibe in feet and miles per hour.
First off, the water temp is holding at 21°, which is a bit cooler than the average for this time of year – about a degree and a half off the normal, so don’t forget the extra rubber.
The first week is pretty grim for the most part. There’s some decent groundswell filling in around the 12th, with a 3ft SSW swell and an 18-second period, and the energy is building solid (684). But the real bright spot is Saturday morning on the 12th. The wind goes glassy – dead flat and clean – and that 3ft SSW groundswell with 18 seconds between waves is going to offer some gorgeous, long-running lines. For a break exposed to the SSW, that’s the window to be in the water.
After that, the quality dries up quickly. Lumpy cross-shore winds and chop take over for days, despite the swell sticking around. The 15th shows a jump to a 5ft swell, but with a fresh cross-breeze, it’s more of a mess than a treat.
The one to circle on the calendar is the morning of the 21st of September. This one is for the experienced crowd only – we’re seeing a solid 7ft SSW swell with a 14-second period and clean, offshore winds. At over 7ft, it’s serious size, but the wind is light and the period is long, giving those waves real power and shape.
Don’t sleep on the morning of the 22nd of September either. The size drops to a more friendly 3ft, but the period is still a nice 16 seconds, with clean offshore wind. That’s a far more manageable day with plenty of energy (937) to keep you moving. Given the SSW direction is spot-on for this break, and crowds can turn up sometimes, it’s worth paddling out early.
There are a lot of flat, crummy days scattered through this outlook, especially the first few and the stretch from the 13th to the 20th. Stick to the windows I’ve pointed out and you’ll find the good stuff.
Rusty.

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.

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.
