The Lowdown

G’day, Rusty here. Let’s have a look at what’s coming up at Cudmirrah Reef.

The next few days are a bit of a mixed bag, but there’s a clear window of decent surf if you know when to paddle out. The water’s sitting at 64°F—that’s 1°F warmer than usual for this time of year, so it’s a touch on the mild side, nothing extreme.

Saturday the 18th is a write-off with tiny, weak swell (79 combined energy) and onshore wind. Not worth the walk.

Sunday morning the 19th though, that’s where it’s at. Glassy conditions, a clean 5ft swell from the ENE with a long 12-second period—real groundswell energy (769 combined energy). That’s the standout of the whole outlook. The reef will handle that long period nicely, shaping up some proper lines. Crowds can be a factor here sometimes, so get in early.

Monday morning the 20th keeps things going with another 5ft ENE swell, 11-second period, and clean cross-offshore breeze. Very surfable, but not quite as glassy as Sunday. The afternoon gets a bit cross and lumpy, so aim for the morning.

Tuesday the 21st still has playable 4ft–5ft swell, glassy in the morning, but the energy drops a bit (335–442 combined energy). Still good fun.

Wednesday the 22nd fades to 3ft–3ft with offshore wind, but it’s ordinary. Thursday the 23rd is a no-go: 8ft short-period S swell (952 combined energy) with cross-on wind—that’s raw and messy, only for the brave and experienced. Short period too, so it’ll be lumpy and hard to ride.

Friday the 24th morning is another highlight. Clean 6ft from the south with an 11-second period and light offshore NW wind (750 combined energy). That’s proper, clean, and lined up. The afternoon gets a little cross-on but still rideable.

After that, it’s a slow decline. Saturday the 25th morning has glassy 3ft southern swell (292 combined energy)—small but clean. From Sunday the 26th right through to the end of the month, it’s mostly small, weak, or blown out. A few moments of clean 2ft–3ft swell but nothing to get excited about.

Into August, the 1st is a write-off with rain and strong onshore winds. Then Sunday the 2nd morning shows a glimmer: 3ft from the ENE with clean cross-offshore breeze (245 combined energy). But it’s a long way off, so keep an eye on it.

Overall, best bet is Sunday the 19th morning for the cleanest, most energetic swell. Friday the 24th morning is the other standout. The rest is patchy—small, weak, or messy.

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.
