The Lowdown
G’day, Rusty here. Let’s cut through the hype and look at the real picture. The next stretch is mostly a battle with wind, but there is one morning that shines above the rest—Sunday the 27th. If you’re flexible, that’s your window. Everything before that is ordinary to poor.
Wednesday 16th is a washout. We’ve got a 3.0m south swell with a big combined energy reading at 1726 – that’s strong – but the wind is fresh and cross-shore from the southwest at 30 km/h. It’s lumpy, cross-choppy, and not surfable in a fun way. Water’s at 19°, which is a hint warmer than average for this time of year.
Thursday 17th eases back to 2.1m, but the wind stays onshore. Light cross-onshore through the day, and it’s still messy.
Friday 18th begins to show promise. The morning is glassy with a 1.3m south swell, and it’s clean. That’s your first real chance. The afternoon goes cross-shore with a light breeze, so it’s still clean but backing off.
Saturday 19th drops to 0.6m. It’s clean in the morning with a light cross-off, but it’s tiny. Not worth getting wet for.
Sunday 20th is a small tease – a long-period 19-second south swell but only 0.5m. The morning is clean, but it’s too small. The afternoon picks up an offshore wind and is clean, but again, no push.
Monday 21st goes bad again. A fresh onshore swing brings it up to 2.0m, but it’s choppy and cross-onshore. Poor quality.
Tuesday 22nd stays poor – 1.8m, moderate cross-onshore. Not worth the effort.
Wednesday 23rd is a turning point. Morning is glassy with a 0.9m south swell – clean but small. The afternoon is the first real highlight: 1.6m from the ENE at 7 seconds, clean with a light cross-off. It’s short-period, but it’s got a bit of push.
Thursday 24th has storms brewing in the afternoon with a strong NNE wind at 25 km/h, but waves hold around 1.9m from the NE. It’s clean in the morning, but the afternoon gets chaotic.
Then you hit the gap – Friday 25th and Saturday 26th are both poor, cross-onshore winds and small, disorganised surf. You’re waiting.
Sunday 27th is the main event. The morning is glassy – dead calm – with a 2.0m NE swell at 8 seconds, and combined energy at 802 (moderate-to-strong). That’s the standout. Clean, punchy, and Cudmirrah Reef will be handling it nicely. The afternoon stays in the mix with a 2.4m cross-off, but it’s a touch more onshore, so the morning is your best bet.
Monday 28th drops back to 1.2m, clean but small. Tuesday 29th is marginal – 1.1m, clean but ordinary. Wednesday 30th stays clean but tiny at 0.8m.
Finally, Thursday 1st October brings a new south pulse at 1.6m but with a short 6-second period. The morning is cross-off and clean, but the afternoon goes cloudy and onshore with a 0.8m ENE. A mixed bag.
So, to keep it simple: the run starts poorly, and the only real window of goodness is Sunday morning the 27th – glassy, 2.0m, clean. Everything else is either too small, too windy, or too messy. If you can wait for that, you’ll get the best session of the fortnight.
Rusty out.

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