The Lowdown

Alright, let's take a look at the next couple of weeks. Honestly, it’s a bit of a tough stretch ahead. The surf is going to be there, but the wind is going to be the main problem. For the first week, from now until about the 10th, we’ve got solid ENE swell pulsing in, but it’s coming with a persistent cross-onshore breeze that's going to make a mess of things. The best chance for anything decent looks to be around Monday the 7th and Tuesday the 8th, when the wind finally shifts offshore.

The standout window is Tuesday, September 8th. We’ve got a 6ft swell from the ENE, with an 11-second period, and more importantly, moderate offshore wind from the south. It’s going to be clean, with moderate wave energy (789). That’s your session right there. It’s an exposed spot, so it’ll pick up that swell well. The water is a balmy 81°, which is about average for this time of year.

Before that, Monday the 7th afternoon could be worth a look too. The swell bumps up to 7ft from the ENE with a 12-second period, and the wind goes cross-offshore from the ESE. It won't be as clean as Tuesday, but the energy is strong (1428) and it's described as clean.

After that, the wind turns back onshore and the swell drops off. From the 9th through to the 11th, the swell gets smaller and the period drops way down to 7-8 seconds, making for weak, lumpy conditions. The energy values are in the 300s – really just not worth paddling out for.

Then from the 12th to the 16th, we see another pulse of ENE swell, mostly in the 6ft to 7ft range, but the period stays short (7-8 seconds) and the cross-onshore wind is relentless. The energy picks up into the 400s and 500s, but with that wind and short period, it’s going to be a bumpy, choppy mess. The wave comments all say “poor surf conditions” – I’d be looking elsewhere.

The last few days, from the 17th to the 20th, the swell fades away. Heights drop from 6ft down to 4ft, period stays short at 8-9 seconds, and the onshore wind sticks around. Energy drops from 425 down to 170. It’s pretty much a write-off.

So, to sum it up: if you’ve got a window, make it Tuesday the 8th for the cleanest conditions. Monday the 7th afternoon is a backup. The rest of the 16 days is mostly a fight against the wind.

A general guide to surfing at Rabbit/Manana Island can be found by selecting the local surf guide option on the grey menu.

If you surf the same spot (Rabbit/Manana Island) 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 Rabbit/Manana Island 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.
