The Lowdown
Alright, Rusty here again. Let's see what's cookin' for Cudmirrah Reef.
The first few days are pretty flat and quiet. The water's about 62°, normal for the season. Nothing much happening.
Monday the 31st of August starts with a weak 3ft southerly swell, 9-second period, and 203 energy. The cross-on breeze from the ENE makes it poor. Tuesday the 1st of September is a little cleaner with an offshore NW wind, but the swell is still only 3ft at 11 seconds. Surfable, but nothing special. Wednesday and Thursday stay small with clean offshore winds, but the energy fades away.
Friday the 4th of September has a glassy morning with a 2ft southerly swell, 8 seconds, and 119 energy. Small, but clean. The afternoon goes offshore. Saturday the 5th gets blown out by a 35 km/h offshore wind, and the swell drops to 2ft. Sunday the 6th morning is glassy with a 4ft southerly swell at 8 seconds and 188 energy – a small, clean session, but the afternoon goes choppy.
Now the good stuff. Monday the 7th of September afternoon: a 6ft northeasterly swell, 6-second period, and 339 energy. The wind is offshore from the NW, moderate and clean. Expect good surf. This is the first real standout.
Tuesday the 8th is messy, but Wednesday the 9th of September morning brings a massive 15ft southerly swell, 10-second period, and a huge 4377 energy. Light cross-on wind from the SSE. This is big, heavy swell. Over 2.5m (8ft), so experts only. A powerful groundswell, but the cross-on wind will put some bumps on it.
Thursday the 10th of September morning is the absolute standout. Glassy, with a 10ft southeasterly swell, 10 seconds, and 1600 energy. The report says "excellent surf conditions for experienced surfers." Clean, glassy, and solid. That's the one.
From Friday the 11th onward, the swell drops. Friday morning has a 5ft easterly swell, 10 seconds, and 540 energy, but the wind is cross-on. The weekend of the 12th and 13th offers some cleanish morning options around 4ft to 3ft, but nothing special. The second week, from the 14th of September, is quiet with tiny, weak swell and poor conditions. The 15th of September Tuesday morning has only 2ft swell and 43 energy – a total flat spell.
Best bets: Thursday the 10th of September morning – glassy, 10ft SE swell, clean and powerful. Also Monday the 7th of September afternoon with 6ft NE swell and offshore wind. The big Wednesday the 9th session is for the hardcore crew only.
Rusty out.

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.
