The Lowdown
G’day, Rusty here. Let’s get straight into it. We’ve got a long stretch ahead, and to be honest, the first couple of days are pretty flat and messy. Nothing really happens until Thursday the 20th, and even then it’s small. If you’re keen, you’ll be working for scraps.
The real story starts to build from Friday the 21st. That’s when the swell starts to wake up, and it looks like we’ve got a solid run of groundswell coming through. The standouts are Friday morning and then Sunday the 23rd. Friday morning, Ambinanibe should be handling that 4.3ft SSW swell with a 13-second period, and the wind is light and offshore from the west. That’s the cleanest you’ll see it for a while. The water’s at 72.9°, which is about normal for this time of year, so no surprises there.
Sunday the 23rd is the other one to circle. The swell is a touch bigger at 5.2ft, still from the SSW, and the wind drops to almost nothing – glassy conditions. That’s going to be pure, lined-up waves. This spot can get a bit of a crowd, so get in early.
The swell really pumps up from the 25th onwards, but it gets tricky. We’re looking at 8.2ft plus, and that’s serious size. It’s not for the faint-hearted, and the wind swings onshore in the afternoons, chopping it up. The energy in the water gets huge – we’re talking combined energy readings in the thousands, which is strong stuff. For a few days there it’s going to be big, raw, and not all that clean. If you’re an expert, there will be moments in the mornings, but expect challenging conditions.
Then we see it start to fade from the 28th, and the second week drops right off. The energy weakens considerably. We’re back to small, weak, and generally poor surf through to the end of the run. There’s a little bump around the 1st of September, but the wind is all over it. Don’t get your hopes up for that period.
So, bottom line: Friday the 21st morning and Sunday the 23rd are your best bets. Everything else is either too small, too lumpy, or too damn big. Stay sharp.

A general guide to surfing at Ambinanibe can be found by selecting the local surf guide option on the grey menu.

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.
