The Lowdown
G’day, Rusty here. Let’s have a look at what’s cooking for the Noosa region.
Overall, it’s a pretty quiet stretch. Don’t get too excited early on—there’s a lot of average to poor conditions in the first week, with a few windows that are just about passable. The real standout, and honestly the only one I’d paddle out for, comes late in the period.
We kick off on Wednesday the 19th of August morning with rain showers and a 6ft swell from the ESE on a short 8-second period. The combined swell energy is moderate at 375. Winds are cross-off at 12 mph, so it’s clean, but the swell is a bit messy and the tide might mess with it. Not great, but not a complete write-off. The afternoon drops to 4ft and goes more onshore, so that’s done.
Thursday the 20th morning is poor – 3ft, cross wind, chop. But Thursday afternoon pulls up a bit: 6ft from the E, 8 seconds, and a gentle cross-off breeze at 9 mph. Combined energy jumps to 346, and the wave comment says “expect good surf conditions.” This is the best of the first week, no doubt. Clean, punchy little waves. The Groin (Noosa) handles this direction well, and it’s a breakwater setup, so it’ll be fun for beginners and intermediates alike. Water temp is about average for this time of year, so no wetsuit drama.
Friday the 21st through to Sunday the 23rd is mostly ordinary – small waves, cross or light onshore winds, nothing worth the drive.
Monday the 24th morning offers a rare glassy moment: 3ft from the ENE, 7 seconds, and glassy conditions with just 3 mph winds. Combined energy is weak at 99. Surfable but very ordinary. The afternoon goes cross-on again.
Then we hit a real flat spell. From Tuesday the 25th right through to Sunday the 30th of August, it’s tiny—2ft to 3ft—with poor conditions. Some glassy mornings but barely a ripple. You’d be better off doing something else.
Now, here’s the one that’s worth circling. Monday the 31st of August morning: 5ft from the E, 8-second period, combined energy of 230—moderate. Winds are cross-off from the S at 9 mph, clean, and the wave comment says “surfable waves but very ordinary conditions.” Look, I know that doesn’t sound like a rave, but for this stretch it’s the highlight. It’s a small but clean, workable wave at The Groin. The afternoon gets a touch bigger at 5ft from the ESE, but the wind picks up to 12 mph. Still cross-off, still clean, but the period drops to 7 seconds so it’ll be lumpy.
After that, Tuesday the 1st of September and Wednesday the 2nd of September have some size—4ft to 4ft—but the wind cranks up to 19-22 mph from the SSE. That’s a fresh breeze, cross-off, so it’ll be choppy and blown out. Only for the keen or the kooky.
So, bottom line: if you’ve got a window, Thursday the 20th of August afternoon is your pick for the first week—clean, moderate energy, fun little waves. The real standout is Monday the 31st of August morning: clean, 5ft, moderate energy, and the best chance for a decent session. After that, it’s all downhill. Don’t expect much from the rest.
Rusty.

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