The Lowdown

Alright, let’s get into it. This is Rusty, looking at what’s coming up for Cudmirrah Reef over the next couple of weeks.

Right off the bat, Sunday the 6th is a write-off. We’ve got a messy, cross-shore wind and the swell is all over the place – not worth paddling out for.

Monday morning the 7th though, that’s where we start to see a glimmer. The wind goes glassy, light air, and we get a 5ft swell from the SSE with a 9-second period. The combined wave energy is moderate (308). It’s not massive, but it’ll be clean and offers a real chance for a session. The water temp is about average for this time of year.

Tuesday the 8th is a bit of a mixed bag – a 7ft swell in the morning but with a cross-onshore breeze, so expect some chop. The energy is moderate (558). It’s a bit ordinary.

Now, hold on to your board for Thursday the 10th. Thursday morning we get a 8ft SSE swell with a 10-second period, energy is strong (1239), but the wind is light and cross-onshore. The real standout is Thursday afternoon: a solid 10ft S swell, with a very long 13-second period. The combined energy is very strong (4444). This is a big, powerful groundswell. The wind is onshore though, so it will be lumpy. This is expert territory – that size and power is not for the faint-hearted.

Friday the 11th morning is another real highlight. We get a 6ft S swell, 10-second period, and glassy conditions. The energy is moderate (679). This will be clean, lined-up waves on the reef. This is probably the best bet for a quality, user-friendly session.

Things settle down over the weekend of the 12th and 13th, with smaller swells and cross-shore winds. Nothing to get too excited about.

The following week, from Monday the 14th, we get a run of smaller but clean swells. Monday morning is glassy with a 3ft S swell (11-second period, low energy 278). Nice and clean for a longboard or a funboard. Tuesday the 15th morning has a 7ft S swell but with a short 7-second period, so it’ll be a bit lumpy, but the offshore wind will clean it up (580 energy). That’s a solid session for those who can handle the short-period chop.

Thursday the 17th and Friday the 18th both offer clean conditions with moderate offshore or cross-offshore winds, and 4ft to 5ft SSE swells. Consistent, clean, fun waves.

The last few days of the forecast, from the 19th into the 21st, see the swell drop off significantly, down to 2ft. There’s barely any energy (43), and it’s not worth the paddle.

The standout sessions: For the best all-round quality, target Monday morning the 7th (5ft SSE, glassy, clean) and Friday morning the 11th (6ft S, glassy, clean). For the big-wave crew, Thursday afternoon the 10th (10ft S, 13-second period) is the one to circle, but it’s only for experts.

Keep an eye on the wind forecasts, as they’ll change things day to day.

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.
