The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this next couple of weeks is a bit of a tough watch for The Groin (Noosa). We’ve got a long stretch of pretty ordinary conditions, so don’t expect any magic. The water is a bit colder than usual for this time of year at 68°, which is a solid 2° cooler than normal, so you’ll want a good wetsuit.
The week kicks off on Tuesday the 18th with some rain and a 6ft swell from the ESE, but it’s a short-period 8-second wind swell with a moderate wave energy (399). The wind is a cross-off from the SE at 12 mph, which keeps it clean, but the forecast says it’s marginal. That’s the biggest swell of the whole period, but it’s not worth getting excited about. That afternoon, the wind picks up to 19 mph and conditions get poor. Wednesday the 19th drops right off to 3ft, period dropping to 7 seconds, and the wind is still cross-off but the surf is just ordinary. Thursday and Friday stay small, around 3ft to 4ft, all short-period, and the wind keeps shifting around, mostly cross or cross-on, keeping things messy. The combined energy stays weak, mostly under 200.
Saturday the 22nd and Sunday the 23rd are pretty much the same story – small 3ft to 4ft E swell, period hovering around 7-8 seconds, and wind is either cross or cross-on. There’s a brief moment on Monday the 24th with a glassy morning and 3ft, but it’s still weak (97 combined energy) and the swell is short-period. After that, it’s a slow fade into the abyss. From the 25th onwards, the swell drops below 3ft, and by the 28th we’re looking at 1ft and 2ft waves with a period of 8-9 seconds. The combined energy plummets to 50 or less. The wind is onshore or cross-on for most of it, with a bit of glassy early on the 28th and 1st of September, but there’s just no push.
The best on offer? Honestly, there’s no standout. The morning of Tuesday the 18th has the biggest swell (6ft) but it’s a short-period wind swell and the conditions are only marginal. If you’re desperate, the glassy morning on Monday the 24th with 3ft might give you a few closeouts, but don’t expect much. The rest is a solid 10-day stretch of tiny, weak, poorly-winded surf. If you’re into kiting, the onshore afternoons might be more fun than paddling.
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.
