The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a bit of a slow start on the horizon, but don’t lose hope. The first week is mostly a washout, with onshore winds and weak energy messing up the shape. The real standout is a window in the second week, so keep your eyes on that.
The water temp is sitting right around average for the time of year, so nothing unusual there.
Thursday the 6th and Friday the 7th are a write-off. Thursday has poor conditions with a cross-off wind and a weak 3ft swell from the SSW. The energy is weak (175). Friday looks a bit better with a long-period 18-second groundswell building, but it’s still marginal. By Saturday morning the 8th, we’re looking at clean 3ft SSW swell, but still poor surf, so not worth paddling out.
Sunday the 9th isn’t much better. Monday the 10th shows a small improvement, with a 4ft SSW swell and moderate energy (515), but the wind is still cross-off, so it’s only marginal.
Now, the one to circle on your calendar is Tuesday morning, August 11th. This is the best session on offer. The wind goes glassy, a light WSW breeze, and the swell is a clean 4ft from the SSW with a 14-second period. The energy is pumping at 612, and the conditions are calling for *very good surf*. This is your window. The break is Ambinanibe, and it’s exposed to the SW swell, which is right on the money. Keep in mind, crowds are possible here.
After that, Wednesday the 12th sees a jump in size to 8ft from the S, but with a shorter period of 11 seconds and a cross-on wind. That’s more for experts, and the energy is strong (2032), but the wind isn’t doing any favours.
Thursday the 13th drops a bit to 8ft, still S swell, but the wind is onshore. Friday the 14th sees a nice long-period groundswell (20 seconds) from the SSW, but only 3ft and light cross-off wind. It’s marginal but could be a fun, clean longboard session if you’re patient.
Saturday the 15th has a strong 7ft S swell with a very long 17-second period, and the wind is light cross. The energy is massive (2385), but with that period, it’s going to break straight at this beach. It’s better suited for a point or reef, so keep that in mind.
Sunday morning the 16th is another glassy session, with a 3ft SSW swell and 15-second period. The energy is solid (730), and it’s clean. A good backup option.
The last week trails off into weak, small swells again from the 18th onwards, with mostly poor conditions.
So, the standout is the morning of Tuesday, August 11th. Get out there.
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.
