The Lowdown
G’day, Rusty here, and I’ve gotta be straight with you – it’s a tough run ahead for Compton Bay. The 16-day window kicks off with a real flat spell, and honestly, there’s no standout session in the whole stretch. The water’s sitting about average for this time of year, so at least you won’t need a thicker wetsuit.
From Friday the 21st of August, right through to around the 25th, we’re looking at tiny swell – barely 0.3 ft to 1 ft, with weak energy levels (4 to 22). The wind’s mostly cross-off or glassy at times, which would be magic if there was any wave to ride, but there isn’t. It’s clean but flat.
Then from Wednesday the 26th of August, the swell tries to kick up a bit. We get a pulse of 4 ft to 4 ft from the SW, but the period is short at 5–6 seconds, so it’s weak and bumpy. The wind turns onshore or cross-on, and it’s messy. By Friday the 28th, energy jumps to 261–485, with swell hitting 6 ft to 8 ft from the SW, but the wind is howling at 19–28 mph from the S and NW – it’s a strong cross-onshore mess. That’s more for kite surfers than paddle surfers.
The weekend of the 30th and 31st keeps the same story: 5 ft to 8 ft swell, but onshore winds and sloppy conditions. The energy stays moderate to strong (up to 508), but it’s all wind-affected and choppy. Hard to get excited about.
Into September, the swell drops right back to 0.7 ft to 2 ft, and the wind stays cross-off at times, but it’s tiny again. There’s a big gap of poor surf from the start, and honestly, nothing in this 16-day window is worth paddling out for. I’d say keep an eye on the forecasts – this area can turn around, but right now, it’s a blank.
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.
