The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
Honestly, it’s a pretty grim stretch ahead. We’re looking at a solid 16-day window, but the first real glimmer of anything worthwhile doesn’t pop up until Wednesday, 15 July. Even that’s a tough sell. The water temp is sitting at 82°F, which is about normal for this time of year, so no surprises there.
The standout—if you can call it that—is Ketewel on Wednesday the 15th. It’s a sheltered reef setup that’s normally inconsistent, so when it does show, you pay attention. We’ve got a 6ft SSW swell rolling in with a very long 16-second period—proper groundswell energy. The combined energy is strong at 1556, so there’s plenty of push. Thing is, the wind is cross-onshore from the ESE at 9 mph, so it’s going to be a bit lumpy and choppy. Not the clean, glassy perfection you’d want for a reef. Still, it’s the best of a bad bunch. That swell is a bit much for beginners, and the crowd situation is sometimes, so you might have company.
Then we hit a massive dead zone. From Thursday the 16th all the way through to the end of the month, the scores are zero. The wind stays stubbornly cross-onshore, the swell drops and gets messy, and the wave quality is just poor. There’s a little spike on Monday the 20th with a 7ft swell and strong energy (2360), but the wind is still cross-onshore and choppy, so it’s more of a kite-surfing setup than a clean paddle session. The period drops to shorter stuff too, so no real shape.
If you’re desperate for a surf, the 15th is the only day that’s even worth a look. After that, put the board away and wait for the pattern to shift.
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.
