The Lowdown
Right then, let’s have a yarn about what’s on the cards for the next couple of weeks around Compton Bay. I’ve gotta be straight with you, it’s looking like a grim stretch of days ahead for a paddle.
What we’ve got here is a long, quiet run with hardly a wave worth getting wet for. The water’s sitting at 70°, which is much warmer than normal for this time of year, so that’s a bit of a surprise, but it doesn’t help the surf.
The whole outlook is basically a bust. Starting from Sunday the 16th, the swell is tiny, coming in from the WSW at only 1ft with a short, weak 8-second period. The combined wave energy is a paltry 11, which is very weak. The wind is glassy in the morning, but the waves are just too small to do anything with. From there it only gets rougher and more blown out as onshore winds kick in, with the swell staying below 2ft for days. There is a slight bump on Tuesday the 18th with a 2ft swell in the morning, but the wind is a messy cross-onshore and the period is a shocking 4 seconds – just wind chop.
We see the heights creep up a bit towards Thursday the 20th, touching 5ft from the WSW on the afternoon, but the period is still short at 5 seconds and the wind is cross-onshore, making it choppy. The combined energy is only moderate at 102, but the quality is poor. It’s a kitesurfer’s breeze, not a surfer’s wave.
After that, it all falls away again. There’s a brief window on Friday the 21st morning and Saturday the 22nd morning with some clean conditions and a light cross-offshore breeze from the N and NNW, but the swell is down to 1ft and 1ft. You’d struggle to get a ride.
The rest of the month is a write-off. The swell drops to near flat, only occasionally pushing up to 3ft on the 28th and 29th, but always with poor onshore or cross-onshore winds that make it choppy. The longest period we see in the whole forecast is 10 seconds on the 23rd, but the swell is only 0.3ft.
Honestly, there are no standouts here. No decent windows at all. If you’re desperate, the morning of Friday the 21st is the cleanest the water will be, but you won’t find a wave over knee-high. This is one of those blank runs that just happens. Forecasts can change, but right now, I’d put the board away for a bit.

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.
