The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming down the pipe for the next couple of weeks.
To be honest, right now we're in a bit of a flat spell. The first proper surf window doesn't show up until Thursday, the 27th of August, and even then it's only marginal. Most of the time we're looking at a persistent cross-onshore breeze from the SE, which is messing with the surface at Ketewel, a sheltered reef break for advanced surfers. The water temp is sitting at 80°, which is right on the money for this time of year.
The real standout window looks like it could be Friday, the 28th of August. We've got a solid SSW groundswell pumping in with a 8ft face and a long 16-second period. The combined energy is massive, hitting 3076, so there's a serious amount of power in the water. That's expert territory for sure. The wind is still a cross-onshore, but the swell size and period are the main draw here. The wind might keep it a bit bumpy, but there's plenty of juice.
After that, the swell drops back down, and we're back into marginal conditions with that same onshore breeze. There is another bump around Tuesday the 1st of September, with 6ft SSW swell and a 17-second period, energy around 1928, but the wind is still going to be a factor. It's a consistent pattern of surf, but the quality is being held back by the wind. For a sheltered spot like Ketewel, the optimum swell direction is from the S, but this SSW swell is close enough to offer some decent shape when the wind calms down.
For a couple of days around the 5th and 6th of September, we see a slight drop in period to 13-14 seconds, which means the waves will be a bit more user-friendly for the beach breaks, but the SE wind is still blowing. It's a long run of marginal surf, but if you're keen, there's always something to sit on.

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.
