The Lowdown

Alright folks, it’s Rusty here with a look at what’s ahead for Cudmirrah Reef.

We’ve got a mixed bag over the next couple of weeks, but there are a couple of clear windows where it’s going to light up nicely. The start of the period is a bit slow, but don’t switch off just yet.

Monday the 10th kicks us off with a decent pulse of 6ft swell from the ENE, period around 9 seconds, and clean with a moderate offshore. The combined energy is solid at 572. Water temp is 63°, about average for this time of year. Afternoon drops a little in size but stays clean. Tuesday the 11th sees the swell shift to the south, with the morning offering 5ft and a nice 11-second period (518 energy) under clean conditions. It’s a pleasant start, but the real standout is yet to come.

The highlight of the whole outlook is Thursday morning, the 13th. That’s your session to circle. We’ve got a solid 7ft swell from the south, but the period is a short 8 seconds, which means it’ll be punchy and a bit dumpy on takeoff. The crucial part is the glassy conditions—zero wind. The combined energy is pumping at 1005, so it’s got plenty of power, but that size and short period make this one for experienced surfers only. Even though the direction is south, this exposed reef will handle it, and with it being an advanced, very consistent spot, it can get crowded. Expect some company for this one.

Things go quiet after that. From Friday the 14th right through to Monday the 17th, it’s a pretty poor run of small, choppy, and onshore conditions. A few days with glass in the morning, but the swell is tiny. There’s a gap of several days with nothing worth paddling for.

We get a bit of a pulse back on Tuesday the 18th with 7ft from the SE, but the wind is on the cross and the period is short at 7 seconds. It’s messy. The morning of Wednesday the 19th is glassy and clean, but with only 3ft of swell (267 energy), it’s a marginal improvement.

Looking further out into the second week, the pattern gets more promising but less certain. Sunday the 23rd and Monday the 24th show some clean conditions with light offshore or cross-offshore winds and 3ft to 5ft of ENE swell, periods around 10 seconds. The energy on Sunday afternoon reaches 394, and it looks manageable. The real tease is Saturday the 22nd morning—clean conditions with 3ft and a 9-second period from the ENE. That’s a fun size, but the afternoon gets blown out by a strong cross-shore. Keep an eye on that morning window.

Overall, the standout is definitely Thursday morning the 13th for the experienced crew. For the rest of us, the tail end of the second week offers hope, but we’ll need to watch the forecasts.

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.
