The Lowdown
Alright, Rusty here again. Let’s talk surf at Ketewel. Water temp’s about 81°F, pretty much average for this time, nothing out of the ordinary.
Honestly, it’s a rough start. From Thursday the 23rd right through the end of July, it’s all poor – cross-onshore winds, choppy water. Swell’s coming in from the SSW and SE, but the wind’s just killing it. Combined energy numbers are moderate to strong (657 to 1372 in that first week), but that doesn’t mean a thing when the surface is blown out. If you want to kite, maybe. For surfing, don’t bother.
The first real glimmer comes on Friday morning the 31st of July. Wind drops to a gentle breeze, still cross-onshore, but lighter. Swell is around 4ft from the SSW, with a long 17-second period – that’s real groundswell energy. Combined energy is strong at 1315. The report calls it “marginal,” and I’d agree – it’s not clean, but there’ll be sets with some push. That continues into Saturday morning, August 1st: 6ft, 17 seconds, still cross-onshore, but the energy is up (1852 combined). You’ll be waiting between sets.
My pick for the best session is Tuesday the 4th of August morning. Solid 7ft from the SSW, 17-second period, combined energy at 2779. Wind is a light cross-onshore breeze. Those big, long-period waves are going to set up nicely on the reef. It’s inconsistent, so you’ll need patience, but the shape and energy will be there for advanced surfers. Crowds are possible, so get there early.
Then on the 5th of August morning, the wind shifts to a light onshore breeze from the SSE – that’s actually offshore for Ketewel. That’s the cleanest wind we’ll see in this entire forecast. Swell is 7ft, 15-second period, combined 1822. That’s the one to circle, but it’s far out, so don’t book your flights yet.
Later, Friday the 7th of August afternoon, wave height drops to 4ft, but the period stretches to 20 seconds – very long period groundswell, combined energy of 2682. That’ll wrap in with a lot of push but the cross-onshore wind still keeps it from being glassy.
So, first week is a bust. The run from July 31st through August 7th has some real potential, especially the 4th and 5th. Set your expectations low for perfection, but if you’re keen, there’ll be waves to ride.
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.
