The Lowdown
Alright, Rusty here. Let’s break down what’s happening.
We’re looking at Flynns Reef, a reef break that’s pretty consistent. The wind is going to be the main character in this story, and it’s not a friendly one for most of the run. The water temp is about normal for the season.
The one standout is Thursday afternoon, August 27th. The wind goes completely glassy. The swell is a clean 3ft from the SW, with a period of 12 seconds. The total wave energy is moderate at 332. For a reef break, that’s a dream setup – clean, long-period groundswell with no wind to mess it up. That’s your best bet.
After that, it gets ugly. Friday the 28th morning has a 4ft SW groundswell with a super long 18-second period, and the energy is strong at 1363, but the wind is onshore and will ruin it. That afternoon, the swell jumps to 6ft, but it’s cross-on and choppy. Saturday the 29th is the same story.
Monday the 31st of August is a bit of a wildcard. The swell is 6ft from the SW, with a period of 15 seconds – that’s a very long groundswell. The energy is strong at 1314. The wind is light, so it’s a marginal call, but it could give you some good, powerful waves on the reef if the wind stays light. It’s worth a look.
The rest of the run is a write-off. Tuesday the 1st of September has strong winds, and Wednesday the 2nd of September sees a big 8ft WSW swell, but with onshore winds. That’s for experts only, and even then, it won’t be clean. The week after that is mostly lumpy and blown out.
So, the simple truth: Thursday afternoon, August 27th, is the only day that looks truly clean. The Monday the 31st of August is a possibility if you’re keen. The rest is a wind battle.
Rusty.

Information about the Flynns Reef Surf forecast
The above surf forecast table for Flynns Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Flynns Reef can be found by selecting the local surf guide option on the grey menu. Our Flynns 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 (Flynns 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 Flynns 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.
