The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this Noosa stretch is having a bit of a quiet spell. The real action is pretty much a one-morning wonder, then a long, slow dribble of small stuff that’s hardly worth paddling out for. If you’ve got a window, make it Wednesday morning the 19th of August, because that’s the standout.
The Groin (Noosa) kicks off Tuesday the 18th with a bit of a messy start. Tuesday morning has a 7ft swell from the ESE, but it’s a short-period 8 seconds with a cross-off breeze and moderate energy (437). The water’s sitting at 68°, which is a bit colder than normal for this time of year. The afternoon goes flat and poor with a fresh 19 mph SE wind – not worth a look.
Now, Wednesday morning the 19th – this is your best chance. The swell holds at 7ft, still from the ESE, period 8 seconds, and the combined energy jumps up to a solid moderate (763). The wind is a gentle cross-off from the SE, keeping things clean. The forecast says expect very good surf conditions. It’s a bit of a push for beginners at that size, but for the crew who know the line-up, it’s the highlight of the whole run. The afternoon drops off quickly to 4ft and poor conditions.
Thursday the 20th is a let-down. Morning has a weak 3ft from the ENE, period 7 seconds, and a cross-shore chop making it ordinary. The afternoon is similar. From there, it’s a long grind. Friday the 21st offers a 4ft morning from the E, but it’s only “surfable but ordinary.” Saturday the 22nd and Sunday the 23rd both have glassy mornings with tiny 4ft and 3ft waves, period 8 seconds, but the energy is weak (137 and 124). You might get a few fun ones if you’re desperate, but it’s not turning heads.
From Monday the 24th all the way through to Wednesday the 2nd of September, it’s a long stretch of flat to tiny waves – mostly 1ft to 3ft, with poor conditions and onshore or cross-onshore winds. There’s a brief moment on Sunday the 30th of August morning with a 3ft clean offshore breeze from the SW, but it’s a 6-second period and only 60 energy – barely a ripple. The rest is a write-off.
So, bottom line: Wednesday morning the 19th of August is the only true standout. The Groin will have clean, solid 7ft surf from the ESE with a gentle cross-off wind. Get in early, because after that, it’s a long wait for the next proper wave.
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.

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.
