The Lowdown

Alright, Rusty here. Let’s talk about Aoura.

Right now, it’s a pretty grim picture. The whole first week is a write-off – we’ve got a solid run of poor surf through the end of August and into early September. Winds are mostly cross-onshore or onshore, and the sea state is choppy, lumpy, or unknown. The storm risk is high through the middle of that stretch, and the energy in the water is mostly from a weak, short-period swell, so don’t even bother with the board. From the 1st to the 3rd of September, the swell does bump up a bit, but it’s blown out by strong, onshore winds, making it unsurfable for a paddle surfer. If you’re into kites, those days might be worth a look, but for a surfboard, it’s a no-go.

There’s a 4-day gap of nothing worth mentioning until the morning of Sunday the 5th of September. That’s when things start to shift. The wind goes light and cross-offshore, and the surf cleans right up. We get a 8ft to 8ft swell from the ESE, with the combined energy sitting around 800-900 (moderate). The period is 9 seconds, so it’s not super long, but with those clean conditions, it’s the first real glimmer of hope. It’s a reef break that rarely breaks well, so when it does, and it’s clean, you want to be there. Crowds are often, so expect company if you paddle out. This is a standout moment for the area.

Moving into Monday the 6th, the swell jumps up to 10ft to 12ft. It’s clean and cross-offshore, but this is pushing into expert-only territory at over 8ft. The energy is strong (1997 and 2824), but the period shortens a little. Still, a solid session if you’ve got the chops.

After that, Tuesday and Wednesday (7th & 8th) drop off quickly in swell size and the wind picks up again, so we’re back to marginal or poor surf.

The next real standout window is Thursday the 10th of September. The morning brings a 6ft ESE swell with a long period of 13 seconds, light wind, and a score that says excellent for experienced surfers. Look for glassy conditions in the afternoon with a 7ft ESE swell, light and glassy wind. The combined energy is strong at 1065 and 1715. This is the kind of day this spot was made for – long period groundswell wrapping in, clean as a whistle. It’s a reef break, so the long period is a bonus. Experts, mark that date.

Then we get to the big one. Saturday the 12th of September. The morning shows 10ft from the SE, period at 14 seconds, combined energy of 5836 – that’s very strong. Light cross-offshore wind, clean. The afternoon is the absolute gem: 12ft from the SE, period stretching out to 16 seconds, glassy wind, and a combined energy reading of 8648. That’s exceptional, expert-level wave energy. For a reef break that gets inconsistent, this event is the one to wait for. Just keep in mind that with that long period and those sizes, it’s strictly for the well-seasoned crew.

The water temperature at the start of this outlook is 84°F, with an anomaly of only 0.4°F, so about normal for this time of year – warm water, boardshorts all day.

So, to sum it up: the next week is a wash. Don’t even think about it. The real standout is Thursday the 10th, with clean, long-period swells, and the absolute bomb is the afternoon of Saturday the 12th. That’s the one to circle on the calendar, even if it’s two weeks out and a bit less certain. Get on it if you can handle it.

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.
