The Lowdown
G’day, Rusty here. Let’s run through what’s on the cards for Ketewel.
Right now, there’s not much happening. The first real chance to get wet is Sunday the 13th, and even then it’s only just okay. We’ve got a 6ft SSW swell with a very long 17-second period, and the energy is way up there (2089). That long period means proper groundswell – good shape, but on a reef like Ketewel it can be a bit straight on the drop. Wind is cross-onshore from the ESE at 9 mph, so it’ll be a bit choppy. Water temp is 80°, right on average for this time of year. This is an advanced break and it doesn’t break all the time, so don’t bank on it. Crowds can show up sometimes.
From Monday the 14th through to Tuesday the 22nd, it’s mostly poor or marginal. Swell sits between 4ft and 6ft, periods dropping to 13–16 seconds, and cross-onshore winds keep things messy. The energy is moderate, usually between 750 and 1600. A few mornings have onshore wind, which might clean it up a little, but honestly, it’s a long run of nothing special.
There’s a small uptick on Wednesday the 23rd. The morning brings a 7ft SSW swell at 16 seconds, with energy climbing to 2025. Wind is still cross-onshore from the SE at 9 mph, so not perfect, but the size and period are there. It’s still only a marginal call.
The real standout is Sunday the 27th and Monday the 28th. Sunday afternoon sees an 8ft SSW swell with a very long 20-second period, and energy rockets up to 5991 – that’s serious power. Monday morning holds 8ft at 18 seconds, energy at 4386. This is big, powerful groundswell. For a reef, that long period is perfect – expect well-shaped, meaty waves, but long lulls between sets. Wind is cross-onshore from the SE at 9 mph, so it won’t be glassy, but it’s workable. At 8ft, this is for experienced surfers only. Beginners, give it a miss. This is the best call of the whole outlook, but it’s still a week and a half out, so don’t lock in your plans just yet.
After that, things drop off again into the end of September, with smaller swell and similar wind.
So, Ketewel is pretty quiet for the first couple of weeks. The big pulse at the end of the month is the one to watch. Stay tuned.
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.
