The Lowdown
Alright, let’s get into it. The next couple of weeks here are a bit of a mixed bag, to be honest. We’ve got some punchy swells lining up, but the wind is going to be a constant thorn in our side. It’s not going to be all-time, but there are a couple of windows that’ll get the heart rate up if you’re willing to work for it.
Right out of the gate, Wednesday the 16th is pretty poor. We’re looking at chest-high waves, maybe 5.2ft, but it’s cross-onshore and choppy. The energy is there, a moderate 1074, but the quality is just junk. You’d be fighting it the whole time. Not worth a paddle.
Thursday and Friday are more of the same – clean skies but onshore winds, so the surface stays messy. The swell stays in that 4.6ft to 5.9ft range, but it’s all over the place. The energy dips a bit on Friday, down to 894, and the waves just don’t have any push. You’re better off waiting for something better.
The weekend, the 19th and 20th, is a strange one. Saturday drops right out to a weak 3.6ft and the energy fades to 689. It’s pretty gutless. Sunday, though, things start to wake up. The swell builds to 5.9ft, maybe 6.2ft on the afternoon, with energy jumping up to 1690. The period stretches out to 16 seconds, so it’s got some proper groundswell in it. But, again, that pesky cross-onshore wind messes up the face. It’s a tease, really.
Monday the 21st is similar, with 5.2ft to 5.6ft swell and moderate energy around 1314. Still just a bit too lumpy to call it good. Tuesday the 22nd fades again to 4.3ft, and by the afternoon the wind is picking up to 12 mph, so it’s choppy and onshore. A real low point.
Now, here’s where it gets interesting. The 23rd of September is the first real standout. The swell pushes back up to 6.6ft in the morning, building to 6.9ft by the afternoon. The energy jumps to over 2000, which is solid moderate to strong. The period is 16 seconds, so there’s some real grunt behind it. The wind is still cross-onshore, but it’s lighter, and the surface should be a bit cleaner. This is the best of the first week, but it’s still not perfect.
After that, we drift back down. The 24th and 25th drop off to 4.6ft to 5.2ft with energy fading back under 1000. Poor conditions, onshore winds, and the wave state is just poor. You’ll be scratching for anything rideable.
But hold on, because things get proper exciting for the final stretch. Saturday the 26th is a game changer. The morning starts with a small 3.6ft south swell, but the period is a massive 22 seconds. That’s a long, long period groundswell. And the energy is already at 2019. Then, the afternoon sees the swell jump to 7.2ft with the period still at 20 seconds. The energy absolutely explodes to 4145. This is strong energy. The wind is light and cross-onshore, which is the best we’ve seen. This is going to be a proper day.
Then Sunday the 27th is the big one. Overnight, that swell fills in to a solid 9.8ft. The energy is at 4807, which is very strong. The period is still a solid 18 seconds. This is a serious, serious swell. It’s going to be big, powerful, and definitely not for the

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 Ketewel 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.
