The Lowdown
Alright, let’s get into it for Cudmirrah Reef. Water temp is about 63°F, which is right where it should be for this time of year.
We’ve got a long dry spell ahead. The first bit of surf shows up Sunday the 16th, but it’s just a 3ft S swell (11 seconds) with light rain and a light SSE wind—nothing to write home about. Monday through Wednesday are even smaller, with swell dropping to 2ft or less and periods of 6–9 seconds. The best of that weak stretch is Tuesday morning the 18th with glassy conditions and 2ft S swell, but it’s barely surfable.
The combined energy stays under 130 until the 20th, then drops into the 20s and teens from the 21st to the 24th. That’s just a trickle.
There’s a pulse on the 25th—4ft S swell (10 seconds) but the wind is cross and cross-onshore, so it’s rough and choppy. Energy jumps to 406, but quality is poor. Then on the 27th, a 5ft NE swell hits with a stiff 30 km/h SSW wind—still no good.
The big one comes on Monday the 31st. Cudmirrah Reef gets a solid 11ft S swell (9 seconds) with a light WNW breeze and clean conditions. Combined energy is a massive 2272—that’s serious power. This is for experts only. The afternoon glass-off with 10ft SSE swell and glassy conditions is a dream for the experienced crew. This is a reef, so keep your head on a swivel.
Most of the forecast is small and messy, but that last day of August is the real deal. Big, clean, and powerful. Just be ready for the wait.

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.
