The Lowdown
Alright, Rusty here. Let’s take a look at what’s cookin’ for Cudmirrah Reef.
We’ve got a stretch ahead that’s pretty average for the most part. The start of the period is a bit of a write-off, with poor surf and choppy conditions. The water temp is sitting at 63°F, which is about normal for this time of year, so no surprises there.
Wednesday, August 26th – not much to get excited about. Cross-on wind from the south, sloppy 3ft to 3ft swell with a short period of 6 to 7 seconds. The combined energy is weak (255) in the morning, bumping to moderate (313) in the arvo, but still poor surf. No point paddling out.
Thursday, August 27th – the morning shows a bit more push with 5ft swell from the south, period up to 8 seconds, and combined energy hitting 879 – that’s moderate to strong energy. But the wind is still cross-on from the south, and the quality is only marginal. Might be worth a look if you’re desperate, but it’s not great. The arvo drops to 3ft and the wind swings cross-on from the ESE.
Friday, August 28th – a bit of a shift. Morning sees 5ft from the SSE with a 10-second period, combined energy of 614 (moderate). Wind is cross from the SSW, light breeze. It’s still marginal, but better than earlier in the week. The arvo cleans up a little with onshore wind from the ESE and 3ft swell.
Saturday, August 29th – small, weak, and cross-on. 3ft from the south with an 8-second period. Energy is moderate (480 morning, 381 arvo), but the wind is a letdown.
Sunday, August 30th – now we’re talkin’. The morning is your standout for the whole period. Glassy conditions, 3ft south swell with an 8-second period, combined energy of 193 (weak). The waves are small, but the surface is clean as a whistle. It’s the only glassy session in the whole outlook, and for a reef break like Cudmirrah, that’s a big deal. The swell direction (S) is close to the optimum (SE), so the shape should be decent. This is the pick of the bunch. The arvo goes back to cross-on and poor.
Monday, August 31st – small drop to 3ft, cross-shore wind from the NE in the morning, but the arvo gets a 12 mph NE breeze – messy.
Tuesday, September 1st – offshore wind from the NW in the morning! 3ft south swell with a long 11-second period, combined energy 176 (weak). Clean, but small. The long period means the reef will handle it well, but don’t expect big waves.
From Wednesday, September 2nd through to Thursday, September 10th – it’s a long run of tiny surf. Most days see 1.0ft to 3ft, with the odd offshore or clean moment, but the energy is very low (mostly under 100, into the 30s and 40s). The swell direction wanders from S to ENE to NE. There’s a glassy morning on Sunday, September 6th with 1ft from the SSW, and Wednesday, September 9th morning is glassy with 2ft, but the waves are just too small to get excited about. The 11th to 12th September shows a tiny bump but still nothing to write home about.
Overall, the Sunday, August 30th morning is the only real standout – glassy, clean, and a proper reef break wave. The rest is a long, drawn-out stretch of small, marginal, or poor surf. Not a lot of energy in the water for the second week.
Rusty.

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.
