The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Cudmirrah Reef over the next couple of weeks. We’ve got a mixed bag, with a quiet start followed by some serious potential later on.
Right now, the reef is seeing some small but clean surf. Sunday morning, 16th August, is glassy with a light 3-foot swell from the south, period around 7 seconds. That’s not a lot of grunt, but the combined energy is moderate at 221, and with zero wind, it’s as clean as it gets. A nice little session if you’re keen. That glassy condition holds into the afternoon with a longer 11-second period.
The start of the week cools off. Monday and Tuesday have tiny, weak waves, mostly under 2 feet, and the wind shifts around. It’s surfable on Tuesday morning with a 2-foot southerly groundswell at 11 seconds, but you’ll be scratching for rides. The energy drops right off.
There’s a long gap of nothing special through Wednesday the 19th to Saturday the 22nd. Mostly small, messy, or onshore conditions. Friday morning, 21st, has a 3-foot clean wave with offshore wind, but it’s short-period ENE swell – not much push. The energy is weak, below 70. Not worth getting excited about.
Now, hang on to your board. By Sunday the 23rd, things change. That morning, a solid 8-foot southerly swell hits, period 8 seconds, and the wind is clean from the north, cross-offshore. The combined energy is a massive 1230 – that’s strong, powerful surf. This is the standout. It’s big, though – over 8 feet – so this is for experienced surfers only. The reef will be working, cranking out clean, chunky walls. Crowds are possible here at times, so be ready for company.
Monday the 24th eases off a little, with a 4-foot southerly swell and clean cross-offshore wind. Combined energy is moderate at 251, and it’s still good. Tuesday the 25th sees another solid pulse, 6 feet from the south, but the wind gets a bit cross. Still surfable.
Into the second week, the waves stay present but the wind picks up. Wednesday the 26th has a big 7-foot southerly groundswell with a very long 12-second period, and clean cross-offshore wind. The energy is enormous at 1995, but the forecast calls it marginal due to tides or conditions. This is a promising but less certain one – look for that window. For experts only again given the size.
The weekend of the 29-30th fades back to small, messy surf. The reef goes quiet again.
Overall, the standout is Sunday morning, 23rd August: big, clean, powerful. Mark it on the calendar. The rest of the run has a few okay sessions, but that’s the one for the crew looking for a proper hit.
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.
