The Lowdown
Alright, I’ll level with you, Ketewel is all we’ve got on the menu and it’s not an easy one. The wind is locked in a cross-onshore direction, and the swell is coming from the southeast instead of the south the reef prefers. The first several days are just not worth it—choppy, short period stuff with no clean face. Don't waste your energy.
We start seeing a real possibility around the 31st of July. The wind drops to a light breeze, and the swell period stretches out to 17 seconds. That means the waves have some depth to them—proper groundswell. The swell height is about 1 m, so nothing huge, but the period is promising. Still a slight cross-onshore wind is there, which means the face won't be perfect.
The highlight is definitely Sunday, 2nd of August. The swell pushes up to 2 m, still from the SSW, with a 17-second period. That's a serious amount of energy coming in—combined swell energy at 2731. That means bigger sets, more push, and more power. This is the best-looking day in the whole window for a confident surfer. The reef will turn that long period groundswell into nice, fast lines. The water temp is around 27° and right around normal for this time of year. The wind is a gentle cross-on, so it’s not clean as glass, but it’s workable.
After that, the swell stays in the 2 ft to 2 ft range for the next few days, with good periods, but that cross-onshore wind never really dies completely. The 6th and 7th of August bring another solid push of 2 m to 2 m, again with a 17-second period. Strong energy again—in the 2500–3400 range. But the same caveat: cross-onshore wind. You'll get power, but you won't get perfection.
The biggest swell of the whole forecast shows up on the 8th of August at 3 m with a 17-second period. That's big for Ketewel and combined energy hits 3671. This is expert territory. The cross-onshore wind will make it tricky, but if you’re strong, this is a massive wave day. For most people, it’s too much.
Overall, we have a few genuine windows of good potential, but the wind keeps this from being a classic run. The best call for quality and size is the 2nd of August.

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.
