The Lowdown
Alright, let’s get into it. For the 16-day window, we’ve got a reef setup at Cudmirrah Reef that’s pretty exposed but not firing all that often. The pattern starts slow, picks up a little mid-period, then fades, with a late pulse that might be worth a look.
Thursday 27th August is a no-go. The morning has a 6ft south swell, period 8 seconds, but the wind is cross-on from the south with the combined energy moderate at 474. It’s messy, and the afternoon drops off. The water temp is 63°, with an anomaly of 0.7°, so basically normal for the time of year. Not worth paddling out.
Friday 28th August stays marginal. The morning shows 5ft from the SSE, period 10 seconds, with cross-shore wind. The combined energy is moderate (574). It’s okay but not clean. Afternoon drops off.
Saturday 29th August is the first real standout. The morning has 4ft from the south, period 8 seconds, but the wind is glassy from the SSE at 3 mph. The combined energy is moderate (330), and conditions are glassy. That’s a rare window of clean, small surf on a reef. It’s not big, but it’ll be fun with no wind chop. Crowds are possible here, so keep an eye out.
Sunday 30th and Monday 31st August sees a weird event. Monday morning has only 2ft from the south, but the period jumps to 16 seconds – that’s a very long period groundswell. Combined energy is moderate (372), and it’s glassy. On a reef, that long period will wrap in nicely, but the size is tiny. Worth a look if you’re patient.
Tuesday 1st September through to Thursday 3rd September is poor. The swell drops to 3ft or lower, period 11 seconds, and the energy dips to 174 or less. Winds go offshore from the NNW and WNW, so it’s clean, but the waves are too small to get excited about. A few clean, tiny waves for the experienced.
Friday 4th and Saturday 5th September are weak. The swell is 1.0ft to 2ft, with combined energy as low as 30. Winds are offshore, but it’s flat. No real surf.
Sunday 6th September sees a NE swell at 4ft, period 7 seconds, with cross-off wind. Combined energy is moderate (155). It’s surfable but ordinary. The short period means lumpy, weak waves.
Monday 7th September is the second standout. The morning has 4ft from the south, period 11 seconds, with light offshore wind from the NNW at 3 mph. The combined energy is strong (424), and conditions are clean. That’s a solid, clean groundswell on a reef. Good shape, decent size. This is the best bet in the whole window. Crowds are possible, so get in early.
After that, the rest of the week fades badly. Tuesday 8th to Thursday 10th September sees swell drop to 0.7ft to 3ft, with combined energy as low as 13. Winds are offshore, but it’s flat. Not worth it.
Friday 11th September has a weird spike: the morning has 2ft from the south, period 11 seconds, with glassy conditions and combined energy at 150. It’s small but clean. The afternoon is a mess with a 1.0ft swell from the south, period 21 seconds – that’s an incredibly long period, but the size is tiny and the wind is cross-shore at 12 mph, creating chop. Not good.
Overall, the best surf is on Saturday 29th August morning for glassy, small waves, and Monday 7th September morning for a clean, solid groundswell. The rest is either too small, too windy, or too inconsistent. The long gap between decent days is notable – about a week between the two standouts. Keep an eye on the Monday 7th September session.

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.
