The Lowdown
Alright, Rusty here, let's have a look at what’s on the cards for Compton Bay.
To be straight with you, the outlook over the next sixteen days is pretty bleak. We’ve got a long, frustrating stretch of poor surf conditions ahead. The first real chance of anything rideable is on Wednesday the 16th of September, but even then it’s not great. From now until then, we're looking at a solid gap with barely a ripple worth mentioning. Most days are chopped out, onshore, or just too small to bother with.
The first standout, if you can even call it that, is the afternoon of Wednesday the 16th of September. We’ll see a jump in swell up to around 5 ft from the WSW, but the period is a short 6 seconds. That’s weak, windswell energy, and the combined energy is only moderate (151). It’s a bit of a bumpy mess with a gentle cross-shore wind, so it won’t be pretty, but it’ll be the biggest we’ve seen in a while. Not for beginners at that size.
Later on, Thursday the 17th of September keeps the swell around 4 ft to 5 ft from the WSW, but the wind swings fresh onshore from the WSW, so you’re looking at a real washing machine out there. The energy is coming in at moderate levels (106 to 136), but the quality is just not there for a good paddle.
Honestly, the best conditions we see in the whole period are actually the smallest. On Friday the 18th of September, a morning window with a light NNW cross-offshore breeze at 12 mph gives us clean little 2 ft bumps from the W. It’s tiny, and the period is a non-event at 4 seconds, but at least the surface will be glassy. You’d need a longboard and low expectations.
After that, the wave heights drop off a cliff. From the 19th of September right through to the 24th of September, it’s flat to ankle-snappers – nothing over 2 ft. The winds are light and often clean, even offshore at times on the 20th and 21st of September, but there's simply no swell to push. The combined energy values are pitiful, all under 25. It’s a total blank.
For a spot that’s fairly consistent, this is a painful run. The southwest swell window is not giving us anything substantial. If you’re desperate for a splash, maybe the 16th of September afternoon could offer a few close-outs for a bodyboard, but for a proper surf? Not this window.
Rusty.

Information about the Compton Bay Surf forecast
The above surf forecast table for Compton Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Compton Bay can be found by selecting the local surf guide option on the grey menu. Our Compton Bay 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 (Compton Bay) 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 Compton Bay 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.
