The Lowdown
Alright, Rusty here. Let’s talk about what we’ve got coming up.
First off, the water temp is hovering around 56°F, which is pretty standard for this spot at this time of year. Nothing out of the ordinary.
Right now, it’s a rough start. Through Friday the 21st and Saturday the 22nd, Flynns Reef is getting hammered by a strong, lumpy cross-onshore wind blowing around 19 to 22 mph. There’s swell – about 4ft to 8ft out of the southwest – but the wind is just trashing the surface. Don’t bother.
Then, look here… Sunday the 23rd afternoon is where it all clicks. The southwest swell hangs around 6ft, but the wind drops to glass – dead calm. You’ve got a long-period groundswell at 16 seconds, and the combined energy is real strong (1524). That period means long gaps between sets, but the reef will be handling it perfectly. This is your standout – a wave for the experienced surfer. And the swell direction is exactly what the reef wants.
Monday the 24th gets a bit messy again, but Tuesday the 25th morning cleans right up with a light offshore breeze and 5ft of southwest swell. Very surfable. The afternoon goes glassy again with 4ft – a nice mellow mid-week session.
There’s a quiet spot mid-week, but Thursday the 27th morning offers a small 3ft southwest groundswell with offshore wind. Clean and fun, but nothing big.
Now the one to circle… Tuesday the 1st of September morning. That’s more than a week out, so don’t book your flight yet, but the data shows 5ft of southwest groundswell at 16 seconds, clean conditions, and barely a whisper of wind. The combined energy is strong (1455). That’s a quality, punchy reef wave for the advanced crew.
The rest of the window has a few clean moments, like the 28th and 30th, but the wind’s not perfect and the swell’s a bit average. And from the 2nd all the way through the 5th of September, it’s just strong, messy winds and small, weak swell. That’s a blank stretch.
So for you: Sunday the 23rd of August afternoon is your best bet – glassy, 6ft southwest groundswell on the reef. The other one to watch is Tuesday the 1st of September morning. Fingers crossed it holds.
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.
