The Lowdown

Alright, Rusty here. Let’s break down the next couple of weeks at Curl Curl. To be honest, it’s a bit of a slow burner, with a few quality windows and a fair bit of average stuff in between.

The overall pattern is for small, short-period swell early on, with a lot of onshore breezes messing up the surface. The first decent window is Sunday morning, and then we’re saving the best for the 31st of August. That’s the one to wait for.

Right now, we’re looking at tiny surf. Friday afternoon has a little 3ft NE windswell, but with a 15 km/h north wind, it’s pretty average. The energy is weak at 50, so it’s not worth getting excited about.

Saturday is a total dud. Waves are down around 1ft and the wind is all over the shop. You’d be better off doing anything else.

Now, Sunday the 23rd is the first real standout. The morning is the go. We’ve got a 5ft south swell, but the period is a short 9 seconds, so it won’t have a huge amount of push. The big positive, though, is the wind. It’s forecast to be glassy with just a 5 km/h north breeze, which will leave the surface clean. The energy jumps up to a moderate 360. This is your best bet for the first week. The S direction is solid.

Sunday afternoon, the wind swings around to the NE and the period drops, so it gets a bit choppy. Not ideal.

Monday the 24th morning is another clean window. The S swell is a touch smaller at 3ft with a 10-second period. The cross-off north wind will keep it tidy. Energy is still moderate at 237. It’s worth a paddle if you’ve got the time.

Tuesday afternoon the 25th is a sneaky one. It’s small (5ft) and the period is short from the NE, but the light cross-off wind will have it clean. Energy is moderate at 239. Might be a few fun ones.

Then we hit a poor stretch. The rest of that week and into the weekend is mostly small, messy, and wind-affected. There are rideable waves, but nothing that’s going to blow you away. The swell direction shifts to ENE, which is okay, but the wind keeps ruining it.

Now for the main event. On Monday morning, the 31st of August, we get a proper long-period south groundswell. The height is only 2ft, but the period is a very long 17 seconds. That’s the key. This is a heavy, powerful swell with a strong energy reading of 483. With a light cross-off north wind and clean conditions, this is the pick of the entire outlook. The S direction is perfect for Curly. This one is a real gem. The afternoon sees it bump a bit in size (4ft) but the wind goes cross and it gets more of a chop on it. So get out there in the morning.

The next day, Tuesday the 1st of September, has some solid S swell (3ft, 11s) in the morning with a light, clean WSW wind. Energy is still respectable at 280. It’s a good follow-up, but not quite the same quality.

After that, the swell fades and we’re back to small and ordinary for the second week. There are a few moments – like Friday the 4th morning with a clean 1ft S groundswell, or Saturday the 5th morning with a building S swell and clean offshore winds – but these are for the dedicated. The energy on those days is there (226, 247), but the size is limited.

So, the plan is simple. Get your best surfs in on Sunday morning the 23rd, and then absolutely mark your calendar for Monday morning, the 31st of August. That long-period S swell is the one with all the potential for quality. The rest is about catching the clean windows.

Take it easy.

Rusty.

Information about the Curl Curl Surf forecast

The above surf forecast table for Curl Curl provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Curl Curl can be found by selecting the local surf guide option on the grey menu. Our Curl Curl 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 (Curl Curl) 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 Curl Curl 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.
