Table - best surf conditions forecast for Ketewel over the next 16 days.
The Lowdown
Alright, let’s break down what’s heading for Ketewel. This is a reef break that’s pretty fickle – it’s inconsistent, so you’ll be sitting there a while, and it’s mainly for the advanced surfers. The water’s at 81°, which is pretty normal for this time of year.
We’re looking at a solid 16-day window, but the first week is mostly a write-off with poor to marginal conditions. The wind is mostly cross-onshore from the SE, which is messing with the shape.
The best bet is probably around Friday, 6 September, with a 6ft SSW swell, a 15-second period, and a strong combined energy of 1224. It’s a bit of a let-down with a light cross-onshore breeze, but it’s the best we’ve got. The swell direction is okay for the spot’s preferred S.
For the bigger stuff, there’s a spike on Wednesday, 28 August, with a 8ft SSW swell and a very strong energy of 3037, but it’s only for experts, and the wind is cross-onshore.
Crowds can be a thing at Ketewel sometimes, so you might want to plan around that. Honestly, it’s a waiting game, and the surf isn’t going to be easy.

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.
