The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s lined up for the next couple of weeks. We’ve got a bit of a mixed bag for Cudmirrah Reef, but there are definitely a couple of sessions worth marking on the calendar.

Right off the bat, we start with a little Monday morning treat on the 7th of September. The swell is up at 5ft from the SSE, with a clean 8-second period, and the wind is light and offshore from the NW. The water is about average for this time of year, so no surprises there. The combined energy is moderate (345). It’s not huge, but it’s clean and the reef will be working. This is a solid, honest little session for the advanced crew.

Things get messy from Monday afternoon onwards. The wind swings around and picks up, and the surf gets cross-onshore and choppy. Tuesday morning sees a 8ft S swell with a light cross wind - the energy is strong (1352), but the quality is off. That trend continues through Wednesday, Thursday, and Friday with lumpy, poor conditions and strong winds. By Friday morning the 11th, the wind goes light offshore from the SSE, but the swell is still a bit mixed up at 6ft from the S (633). It’s a marginal call.

Now, the first real standout. Saturday morning, the 12th of September is the one to aim for. The wind goes glassy, the swell is a clean 5ft from the S with a nice 11-second period (556). The energy is moderate. This is a groundswell, and on a reef like Cudmirrah, that longer period will offer up some beautifully shaped waves with longer lulls between sets. It’s going to be clean, and the best on offer across the whole forecast.

The following week is quieter. Sunday the 13th has some clean, smaller waves with a cross-offshore wind, but the swell drops to 3ft and 6ft (160 & 273). Monday the 14th is tiny, with a 2ft and 1ft swell. The 15th and 16th of September bring some more size, but the wind is onshore or cross-onshore, making it choppy. The 17th of September morning has a clean 4ft S swell and light cross-offshore wind (308), another good, but smaller, window.

Then, we get a second standout. Friday afternoon, the 18th of September. The wind goes moderate offshore from the WNW, and the swell jumps to 8ft from the S with a short 7-second period (701). That’s a lot of energy, and with offshore wind, it’ll be a powerful, clean wall. It’s big enough to be for experts only, but that’s a serious session for the right crew.

After that, the 19th and 20th stay clean but the swell fades and the conditions are just marginal. The run ends on the 21st and 22nd with poor, small, and choppy waves.

So, to wrap it up: Saturday the 12th is your best bet for a clean, classic reef session. Friday the 18th is the one for the big-wave chargers if you can handle the power. Get out there if you can.

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.
