The Lowdown
Alright, let’s get real. Aoura’s looking pretty sad for the next while. The first week to ten days is basically a dead loss. We’ve got tiny surf, weak energy readings down in the low hundreds, and the wind’s just trying to ruin any chance we have. Lots of storm clouds around, too. You’d be better off checking your wax supply.
So we’re looking at a big gap, from now through the 23rd, where there’s just nothing worth paddling out for. The swell’s too small and the wind’s on it. It's a proper dry spell.
But then, the 24th, things start to stir. A longer period swell starts to make its way in and the energy jumps up into the thousands. Still, the wind is cross-onshore and it’s messy, so it’s not a goer yet.
The real standout is Tuesday, the 25th. This is the one. We’ve got a serious groundswell from the ESE, about 7ft to 8ft. The period is a long 16 seconds, so there’s proper power behind it. Wave energy is huge, over 2400 and climbing. And the wind? Glassy. Absolutely glassy. This is for experienced crew only – it’s a proper step up. The swell direction is spot on for Aoura. This is the day. The 26th is still pumping, with similar size and power, but a bit of a cross-offshore breeze in the morning keeps it clean. That’s your second-best bet.
Thursday the 27th gets bigger, up to 10ft, but the wind howls offshore at 30-35 mph, making it heavy and hard work. This is big-wave territory.
Then everything goes nuts. The 28th is a full-on blown-out mess with gale-force winds. Forget it. And the 29th? The forecast is for a 28ft to 34ft monster. That’s not a surf session, that’s a survival mission. That’s the ocean telling you to stay home. The energy numbers are astronomical.
After that, things ease off but the quality drops. The 30th still has some size, but the period shortens and it gets lumpy. By the 31st, it’s fading fast.
So the short story: one epic day on the 25th, with the 26th being a solid runner-up. The rest is either flat, blown out, or dangerously oversized. Water’s about 83°, pretty normal for this time of year. Good luck out there.

Information about the Aoura Surf forecast
The above surf forecast table for Aoura provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Aoura can be found by selecting the local surf guide option on the grey menu. Our Aoura 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 (Aoura) 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 Aoura 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.
