The Lowdown
Alright, Rusty here. Let’s get into it.
Alright, look, I’m gonna be straight with you – this forecast is a tough one for us. The whole 16-day window is a mixed bag at best, and most of it is just not worth paddling out for. The highlight, if you can call it that, is a solid pulse of swell around the 28th of August, but the wind is going to be a constant problem, keeping things choppy and messy.
We’re starting off with some decent sized swell, but it’s all cross-onshore. Saturday the 22nd has waves of 7 ft from the SSW with a very long 16 second period, and the combined energy is strong, sitting at 2134. But the ESE wind at 9 mph is making it a messy, choppy affair. Ketewel is a reef break, sheltered from the south, but this wind is just ruining it. The water temp is about average for this time of year.
Sunday the 23rd is much the same story – 6 ft SSW swell, but again cross-onshore. The wind is a gentle breeze, but it’s not clean.
Monday the 24th through to Thursday the 27th is a real rough patch. The wind is onshore or cross-onshore, the swell drops, and the surf quality is just poor. Expect a few days of flat, messy conditions.
Now, Friday the 28th of August is the one that might get your heart racing a little. The swell jumps back up to 8 ft from the SSW, with a long 16 second period, and the combined energy is very strong at 3065. But – and it’s a big but – the wind is still on the cross-shore, not fully offshore. It’s a marginal call, and the tide could be a factor. This is a size for experienced surfers only, and with the wind not perfect, it’s going to be a challenge.
The first week of September shows a few more pulses of size, like the 1st of September with 6 ft and 6 ft SSW swell, but the wind is still cross-onshore or onshore, keeping it bumpy. The energy is strong (2575 and 2581), but the quality just isn’t there.
The rest of the second week drops off again. The wind stays a problem, and the swell size and energy are lower. It’s just not a good run.
So, to sum it up: there’s no true standout session here. The 28th of August has the most size and energy, but the wind will be your enemy. The rest is a long stretch of poor to marginal surf. If you’re desperate, the 28th might be worth a look, but don’t expect perfection. The consistency is low, and it’s a tough forecast.
Rusty.

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.

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.
