The Lowdown
G’day, Rusty here. Let’s break down what’s comin’ for the next couple weeks.
Right off the bat, it’s dead quiet. For the first week and a half, from Tuesday the 11th through to about Saturday the 22nd, there’s barely enough to wet a line. The Groin (Noosa) is the only spot mentioned, and it’s a fairly consistent little breakwater wave, but the swell is tiny – maybe 2ft at best – with low energy and the wind switching around. There are a couple of glassy moments on the first few mornings (Wednesday 12th with a light NW breeze and glassy surface, for example), but with only a 2ft east swell, it’s a flat calm puddle. The water is about 69°, normal for this time of year.
Then things change on Tuesday 18th August. A 7ft east-southeast swell (8-second period) shows up, with combined energy over 521, but the quality’s bad – cross-shore wind and thunderstorms. Not worth it.
Thursday 20th afternoon offers a little something: 4ft east swell (9 seconds) with cross-offshore wind and combined energy of 274. Clean but marginal.
The real standout is Sunday 23rd August into Monday 24th. Sunday morning brings a solid 6ft east-southeast swell (10 seconds) with clean conditions and combined energy of 651. Sunday afternoon jumps to 7ft east swell (10 seconds), still clean, with combined energy of 904. That’s a powerful push. For the pros, Monday 24th morning hits 10ft east-southeast (short-period 8 seconds) with cross-shore wind – expert only, with combined energy at 1225. Monday afternoon settles to 8ft east-southeast (9 seconds) with cross-offshore wind and combined energy of 1070. Conditions are clean throughout, but the swell direction is a little off from The Groin’s sweet spot (ENE). Still, this is the best run of the entire forecast.
By Tuesday 25th morning it drops to a still-fun 6ft east-southeast (9 seconds) with light cross-offshore breeze and combined energy of 547 – a solid session but the swell’s already backing down.
Bottom line: Sunday 23rd afternoon through Monday 24th is your window. It’s going to be crowded for sure, but that’s the price you pay for waves of this size and quality around here. Be ready.
Rusty.

A general guide to surfing at The Groin (Noosa) can be found by selecting the local surf guide option on the grey menu.

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.
