The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Cudmirrah Reef. It’s a bit of a slow start but there’s some real gold waiting for us if we’re patient.
The surf kicks off this Thursday morning, August 6th, with a small 3ft swell from the S but it’s pretty ordinary. The energy is weak (125) and the period is short at 8 seconds, so it’s not doing much. By Friday morning, August 7th, we get a glassy 2ft from the SSE with a bit more period (9s), but still small and weak energy (104). Saturday morning, August 8th, is glassy again but the swell drops to 1ft – that’s barely a ripple. Sunday morning, August 9th, offers a clean 2ft from the ENE, but it’s still weak.
The real standout is Tuesday, August 11th. The morning brings a solid 7ft from the S with 10-second period, and the energy jumps to 797. That’s moderate energy, but it’s the afternoon that’s the pick of the whole period: 7ft from the S, 11 seconds, and a clean offshore WNW breeze at 15 km/h. The combined energy is strong at 1210. This is excellent surf for experienced surfers. The reef will handle that long-period S swell beautifully, and with offshore winds, it’ll be a session to remember.
After that, Wednesday morning, August 12th, is still clean with a 4ft S swell and 260 energy. Then things get a bit messy with onshore winds and chop until the following week.
The next big moment is Monday, August 17th. Morning delivers 8ft from the ESE with an 11-second period and a light W cross-off breeze. The energy is very strong at 1848. That’s big, powerful surf – only for experienced surfers. The afternoon goes absolutely glassy with 8ft and the same 11-second period, energy hitting 1873. This is a beauty. The reef will be firing, but it’s a serious wave.
Tuesday morning, August 18th, is still glassy with a drop to 6ft from the ESE, and 772 energy. Still good. Wednesday morning, August 19th, offers a clean 7ft from the E with 9-second period and 974 energy. And Thursday, August 20th, has a morning session with 5ft from the ESE, 11-second period, offshore NW wind, and 699 energy; the afternoon glassy with 5ft from the E, 11 seconds, and 769. That’s a solid run of clean surf.
The water temperature is about average for this time of year. Nothing unusual there.
Cudmirrah Reef is a reef break, very consistent, and it’s an advanced wave. It’s exposed to the S-SE-ESE swell, and the optimum direction is SE. When those S swells hit with good wind, it’s a proper wave. Crowds are just sometimes, so you might get a few out, but nothing crazy.
The only real standouts are Tuesday, August 11th afternoon, and Monday, August 17th, all day. Those are the sessions to circle on the calendar.
This is Rusty, signing off.

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.
