The Lowdown
Alright mate, Rusty here, checkin' in with a look at what's on the cards for our local stretch.
Right off the bat, we're looking at a real slow start. For the next week or so, it's pretty much a write-off. We're talking tiny, weak dribbles of swell with hardly any energy behind 'em. A few spots might look clean, but you're chasing ankle-biters at best. You're better off finding something else to do until the second week of August.
The real story starts to build from Thursday, the 14th. That's when we see a proper pulse of southerly swell start to push in, but it comes with a messy cross-onshore wind, so it's gonna be choppy and blown out. Not the day to get excited.
Now, hold onto your board, because the standout window is shaping up for the weekend of the 16th and 17th. Saturday the 15th and Sunday the 16th see a massive jump in size. We're talking a solid 13ft to 16ft swell from the SSE, with a long period of 11 to 12 seconds – that's a proper groundswell with some serious grunt. The combined energy figures are huge, into the thousands (5253, 6219, 3795), so that's a lot of power in the water. This is heavy, expert-only territory. For a reef break like Cudmirrah Reef, that long-period SSE swell is gonna wrap in and produce some thick, powerful lines. The best chance at clean conditions looks like Sunday morning the 16th, with a light offshore breeze from the north and clean conditions. That's your pick of the bunch – a serious, heavy wave for the crew who know what they're doing.
Monday the 17th morning is another solid option, with an 8ft swell from the ESE and a clean offshore wind from the NW. Still a powerful wave, but a bit more manageable for strong intermediates. After that, the swell starts to back off and the winds turn messy again, so that window is your best bet.
In short, don't hold your breath for the first week. Mark your calendar for the weekend of August 16th and 17th. It's gonna be big, powerful, and for the experienced crew only. The Saturday is big and bumpy, but Sunday morning is the real deal.
Rusty.

A general guide to surfing at Cudmirrah Reef can be found by selecting the local surf guide option on the grey menu.

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.
