The Lowdown
G'day, Rusty here. Let's have a look at what's coming up for us. We've got a bit of a mixed bag on the cards over the next couple of weeks. The main event is a solid run of swell, but the wind is going to be our biggest headache, keeping things from getting truly classic. The water temp is 80°, which is pretty much what you'd expect for this time of year – no weird anomalies to report.
Right now, and for the next few days, we're looking at a persistent cross-onshore breeze that's making things choppy. The first real standout I can see is on Wednesday, August 19th at Ketewel. We've got a good 7ft to 8ft of SSW groundswell, with a very long period of 17 to 18 seconds. The combined energy is pumping hard (3140 to 3506), so there's plenty of push. The morning of the 19th has the wind labeled as "on," which suggests it could be a touch cleaner than the usual cross-onshore slop. This is an advanced reef break that's usually inconsistent and sheltered, but with this much energy, it should be firing. Keep in mind, it gets big here – over 8ft on the 20th – that's expert territory only. Crowds can pop up here sometimes, so get there early.
After that little peak, the quality drops off again with the wind staying messy, though there's still swell in the water heading into the weekend of the 22nd and 23rd. It's not clean, but there's energy to be had if you're desperate for a paddle. The second half of the outlook, from about Thursday, August 28th into the 30th, shows another pulse of SSW swell picking back up, with the combined energy climbing back over 2000. The wind looks like it might go light and even glassy or offshore at times. That Friday morning, August 28th, looks like a possible highlight with a 7ft SSW swell, 16-second period, and a light 6 mph onshore wind. It's looking more promising for a cleaner session. Crowds are still a possibility.
Overall, it's not an open-and-shut classic period. The wind is the main villain, but there are windows of opportunity, especially on the 19th and again around the 28th. If you're an advanced surfer and can handle the size and the occasional crowd, keep an eye on Ketewel.
Rusty.

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