The Lowdown
Alright, listen up. This is a rough one for the next 16 days from the 12th of August. Ketewel is getting hammered with swell, but the wind is a total bastard. It’s cross-onshore almost the whole time, so the surface is going to be lumpy and hard work. No glassy sessions in sight. The water is 80°, which is about normal for this time of year.
Starting Wednesday morning the 12th, we’ve got a solid 7ft swell from the SSW with a very long period of 17 seconds. That’s proper groundswell, and the energy is a big 2850 (moderate to strong). But the wind is 9 mph from the ESE, cross-on, making it a choppy mess. The wave comment says it’s marginal, and it’s only for the experts. At 8ft, this is big boy territory.
Thursday morning the 13th holds at 8ft from the S, period 17 seconds, energy 3804 (strong). Wind is still cross-on from the ESE. This is a powerful, dirty wave. Honestly, this setup looks more fun for kite surfing than paddle surfing. The chop is just relentless.
The pattern doesn’t let up. Friday morning the 14th has 7ft from the SSW, period 16 seconds, energy 2512. Still cross-on. Saturday morning the 15th has a lighter breeze at 6 mph, but it’s onshore, so the surface is still not clean. The only glimmer of hope is Tuesday morning the 18th, with a lighter 6 mph breeze from the ESE, giving light cross-onshore with small ripples. The swell is 6ft from the SSW. It’s the least bad option, but it’s still not clean.
The second week stays big but the wind stays stubborn. By Thursday the 20th, we’ve got 8ft from the SSW, but the wind is 12 mph from the SE, making it moderate cross-onshore and choppy. Energy is 3322 (strong). Heavy, powerful, messy. Only for the hardcore.
The last few days drop off. Wednesday the 26th only has 5ft from the SSW, wind still cross-on or onshore. Energy drops to 1281 (weak). Period is 15 seconds, so there’s some shape, but the wind won’t give it a break.
No standouts here. The best bet is Tuesday morning the 18th when the wind is lightest. It’s not what we want, but it’s the best of a bad lot. Crowds are possible, but with conditions this average, it might be quiet.

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.
