The Lowdown
Alright, folks, it's Rusty. Let's talk about what's on the menu for Compton Bay. I've got to be straight with you from the start, this isn't shaping up to be a classic. We're looking at a long stretch of nothing special before we might get a little taste of something good.
The first solid window of surf potential is on Saturday the 12th of September. Before that, it's a write-off. We're talking about a solid 12 days of "don't bother" from now until then. The wind is just all wrong, mostly onshore or cross-onshore, and the swell is either too small, too short-period, or just plain messy. Tuesday the 2nd and Wednesday the 3rd of September see some pulses of 7ft and 7ft, but they're coming with a fresh onshore breeze, so it's just a washing machine. Honestly, if you're a kite surfer, that Tuesday with 7ft and a 22 mph WSW wind might look alright, but for a paddle surfer, it's a no-go.
Now, let's jump to Saturday the 12th of September. The morning is where the first real glimmer of hope appears. We've got a light ENE breeze, which is a cross-offshore wind, and the water is actually clean. The swell is a modest 5ft from the WSW, but the period is a short 5 seconds, so it's going to be a bit soft and slow. The combined energy is only about 111 (moderate wave energy), so it's not going to be a barnstormer, but it's clean. The break is Compton Bay, which is an exposed beach, and with a 5ft swell, it's okay for beginners but not ideal. The water temperature is about average for the time of year.
But the real standout happens on Sunday the 13th of September. This is the one to circle. The morning shows a solid 8ft swell from the WSW, with a much better 9-second period. The wind is from the east at 19 mph, which is a clean cross-offshore. The combined energy is a hefty 773 (strong wave energy), so there's a lot of power in the water. The forecast notes say the swell is predicted to be too big for this break, and I agree with that. 8ft on a beach break like Compton Bay with a decent period is going to be a washing machine for the average surfer. This is expert-only territory, and even then, it'll be challenging. The wind makes it clean, but it's going to be big and powerful. The afternoon is still surfable, but the swell drops to 6ft and the score drops, so the morning is the real window for the brave.
So, to sum it up: the first 12 days are a dust bowl. Saturday the 12th offers a clean little session for the patient, but Sunday the 13th is the big one – a powerful, clean swell for experts only. Don't get your hopes up too much, long-range forecasts can change, but that Sunday morning is the only thing that gets my heart rate up.
Stay salty.

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.
