The Lowdown

Alright, let's get into it. This is Cudmirrah Reef, a spot that demands your respect. The water temp is sitting around 64°, which is pretty much normal for this time of year, so no surprises there.

The week kicks off with a bit of a slow start. Tuesday the 21st is worth a look though, with a clean 4ft swell from the ENE and glassy conditions in the morning. The energy is a solid (341) and the sets will have a bit of shape, but it's an advanced wave, so don't be a hero if you're not ready. The afternoon sees a cross-shore creep in, so the window is the morning.

Wednesday the 22nd drops off a bit, with 3ft and clean but ordinary conditions. Thursday the 23rd is a write-off with a tiny 2ft and a messy wind. Friday the 24th is where it starts to get interesting. We get a jump to 6ft from the SSW in the morning, with a solid energy reading (924) and clean conditions. But the real standout on Friday is the afternoon: glassy conditions, a 4ft swell from the S, and a long 13-second period. That's a proper groundswell, and it will groove down that reef. The energy is still strong (788).

Saturday the 25th and Sunday the 26th are a bit of a mixed bag with moderate winds, but the size hangs around 4ft to 5ft. The best surf on offer is the early morning of Monday the 27th. It's a smaller 3ft, but the wind is dead calm, glassy, and the swell is a clean 10-second S. It won't be big, but it will be perfect.

We hit a flat spell from Tuesday the 28th through the morning of Wednesday the 29th. The ocean goes quiet. Then, Wednesday the 29th afternoon is a game-changer. An 12ft swell from the S slams in, with a short, punchy 7-second period, but the energy is massive (2224). The wind is offshore from the NW. This is for experts only. The size and power mean it's a heavy, barreling reef. The crowd factor is a "sometimes" here, but with this size, you'll want it to yourself anyway.

Thursday the 30th is another massive day, with an 8ft to 10ft S swell, glassy in the afternoon, and energy readings over 2000. Friday the 31st holds at 8ft to 10ft but with strong cross-offshore winds, so it's still on but a bit more challenging.

The standout run continues into the first week of August. Saturday the 1st is glassy and 10ft. But the absolute best on offer is Sunday the 2nd of August. A 10ft swell from the S, an 11-second period, and the energy is off the charts at (3807). The wind is a clean offshore. This is the pick of the entire window. It's a big, powerful, and clean swell on a shallow reef.

The swell starts to drop and get messy from Monday the 3rd, with increasing cross-shore and cross-onshore winds through the 4th and 5th, turning the lineup into a lumpy, choppy mess. The window closes out with poor conditions.

So, to sum it up: the first couple of days are for sneaking in a glassy session, but the real fireworks are from the 29th of July through the 2nd of August. If you're an expert, lock in the 29th afternoon and the 2nd of August. That's the big one.

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.
