The Groin (Noosa) Surf Forecast and Surf Report

G’day, Rusty here, and I’ve got the long-range picture for the Noosa region. The Groin’s our only spot on the board, and it starts off slow, but there’s a real pulse of energy coming in the second week that’s worth a look.

We kick off on Tuesday, 11th August, with tiny 2ft easterly swell at 9 seconds, and the combined energy is weak at 108. The wind’s out of the WSW at 9 mph, cross-offshore, so it’s clean, but the waves are just ordinary. Not much to write home about. That afternoon, the wind goes onshore from the NE at 6 mph and the surf drops to 2ft, and it’s a total write-off.

Wednesday 12th August morning is the bright spot for the light-wind crew. Glassy conditions, zero wind, and the same 2ft, 9-second easterly swell (energy 86). It’s tiny, but glassy is a huge plus for a beginner-friendly break like The Groin. You’ll get clean, little peelers if you’re patient. The afternoon gets a NE cross-onshore breeze at 9 mph, and it goes to mush.

From Thursday 13th August through to Monday 18th August, it’s a desert. Swell drops to 2ft, then 1ft, and by the 17th we’re looking at 0.3ft with a long-period 14-second easterly swell (energy 4). The wind is cross-offshore from the SSE or SE, 15-18 mph, keeping the surface clean, but there’s zero wave energy. A 0.3ft, 14-second swell at a breakwater? That’s a flat calm. A solid 5-day gap with no real surf.

Now, here’s the payoff. Wednesday 19th August, we see a jump to 3ft from the ENE at 8 seconds, with combined energy hitting 120 (moderate). Wind is still cross-off from the SSE at 15 mph, but the surf is still rated poor. On Thursday 20th August, the swell builds to 7ft from the ESE at 8 seconds, and the energy jumps to 646 (strong). That’s a serious size, but the period is short (8 seconds), so it’ll be a bit bumpy and jumbled. The wind is cross-offshore, keeping it clean, but 7ft is expert-only territory. For a beginner break, this is a grommet-free zone. Water temp is about average for the time of year.

Friday 21st August holds 6-6ft from the ESE at 10 seconds (energy 614-631), still strong energy, with the wind cross-off from the S at 15 mph. The period at 10 seconds gives the waves a bit more push and shape. Saturday 22nd drops to 5ft, but the wind is a fresh 21 mph from the SE, making it messy. By Sunday 23rd, we’re back to 4ft and cross-shore winds, not great.

The standout in this window is the Thursday 20th August morning—7ft from the ESE, 8-second period, clean cross-offshore wind, and strong energy (646). That’s the biggest, most powerful swell on offer, but it’s only for experts. If you’re after a quieter, cleaner session, the glassy Wednesday 12th morning is your best bet for the small-wave crowd. The Groin can get crowded (often busy), so keep that in mind. Rusty out.
