The Lowdown

Alright, Rusty here. Let's have a look at what's cooking.

First up, we've got a solid run of surf coming in, but it's not all perfect. The water temp is sitting at 64°F, which is pretty much what you'd expect for this time of year, no surprises there.

The first real action kicks off on Friday, 31 July, at Cudmirrah Reef. Early morning, the wind is glassy, and we're seeing a 6ft south swell with a period of 9 seconds. The combined energy is at 508 (moderate), and it's looking like very good surf. This is a standout session for the early period. The only catch is this spot is for advanced surfers only, and it's consistent, so you'll want to be on your game.

The afternoon of the 31st sees the swell bump up to 7ft from the south, but the wind swings cross-onshore, so it gets a bit messy. The energy jumps to 1181 (strong), but the quality drops. Not the pick.

The weekend is a bit of a write-off. Saturday, 1 August, is clean but small, with 5ft SSE swell and cross winds, and the energy is only 363 (moderate). The morning is a marginal call, and the afternoon is similar. Not the best.

Sunday, 2 August, is a different story. The morning delivers a 5ft SSE groundswell with a period of 12 seconds, and we have nice cross-off winds. The energy is 706 (moderate), and the condition is clean. This is a good one, especially for a reef break like Cudmirrah, where the longer period will shape up nicely. The wind holds for the afternoon too, with 4ft surf and clean conditions.

After that, the surf drops off. Monday, 3 August, sees small 3ft waves, and by Tuesday, 4 August, it's flat, with only 0.7ft on offer for a couple of days. That's a real gap in the action.

But hang in there, because Wednesday, 5 August, brings back some hope. The morning has 4ft S swell with clean cross-off winds, and the afternoon goes glassy with 4ft S swell. The energy is 293 and 310 (moderate), and it's good, clean surf.

The next real standout is Thursday, 6 August. The morning session has a 6ft south swell, period of 9 seconds, and light cross-off winds. The energy is 560 (moderate), and it's shaping up to be very good. This is the best of the week, no doubt. The afternoon gets a bit onshore, so get it early.

After that, we have a few more days of smaller, cleaner surf – Friday, 7 August, has a glassy 5ft SSE swell in the morning, which is a nice session. The energy is 220 (moderate). Then it drops again.

Looking further out, Monday, 10 August, has a pulse of 7ft SSW swell in the afternoon with a period of 11 seconds and cross-off winds. The energy is 1649 (strong to very strong), but the conditions are marginal. This one is a promise, but it's a week away, so keep an eye on it. The morning of 11 August also has 6ft S swell with clean winds, but it's also a bit iffy.

Overall, the best on offer is the Friday 31 July morning and the Thursday 6 August morning. Both have decent swell, glassy or clean wind, and very good conditions. The Sunday 2 August morning is also a solid session. The rest is a mix of small or windy days, with a few scattered good ones in the second week but less certain.

For the advanced crew, Cudmirrah Reef is your spot. It's consistent, but it's a reef, so it can get a bit heavy. For the rest of us, there's not much else to choose from here.

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.
