Gunnamatta Beach Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s coming down the line for us.

This is going to be a mixed bag with a few real gems if you’re willing to wait. The ocean is a bit stirred up early on, and conditions are choppy or onshore for the first week, but we’ve got some stunners in the second half.

The first swell of note arrives on the 9th, but it’s a bit of a tease. Gunnamatta Beach sees a 4ft SW swell with a fresh offshore wind on Sunday morning, which makes for clean faces, but the wave energy is moderate at 649. The water temp is sitting at 57°F, which is about average for this time of year. The afternoon swings to a cross-off but the wind picks up. Not the best session, but a sign of life.

Monday the 10th brings a bigger bump—6ft SW groundswell with a very long 19-second period. That’s a heap of power (2734 energy), but by the afternoon, that onshore SW wind at 28 mph ruins it. Not for us. Tuesday the 11th is similar: lumpy cross-shore wind and 5ft swell. Still not clean.

Wednesday through to the following weekend (12th to 15th) is a write-off for good surfing. The swell hangs around 8ft to 8ft, which is too big for beginners and only for experts, but the winds are mostly onshore or cross-onshore, making it a choppy, messy affair. A couple of those mornings are borderline, but honestly, it’s more of a kite-surfing setup than a clean paddle session.

Now, the turnaround comes on Monday, August 17th. We get a 5ft SW swell with a light offshore wind from the north. That’s clean, and the energy is solid at 827. The real standout, though, is Monday afternoon: 4ft SW swell but with a 16-second period and a light offshore from the ENE. The conditions are described as excellent for experienced surfers. The wave energy is 1036, and it’s glassy. This is a long-period groundswell, so it’ll be best on the points and reefs rather than the beach, but it’ll be a classic session if you pick your bank.

Tuesday, August 18th is the absolute peak of the window. In the morning, 4ft SW swell with a 14-second period, clean offshore from the north. But the afternoon is perfection: 4ft SW swell, 14-second period, and glassy conditions with barely a breath of wind. Energy at 1103. That’s as good as it gets for this spot. Crowds are likely with “often” listed, but for a session that clean, you’ll take the company.

Wednesday the 19th keeps the run going with clean 4ft SW swell and a 16-second period in the morning and a lighter wind in the arvo. Good energy (858). Saturday, August 22nd, also offers a clean 5ft SW swell with a light offshore in the morning.

A couple more longer-range callouts: Sunday, August 23rd morning looks promising but less certain. A 7ft SW swell with a 17-second period and glassy conditions is a big one, but it’s over two weeks away. If it comes together, that’s a big, clean groundswell for the experienced crew.

All up, the standout days are Monday 17th afternoon and Tuesday 18th, especially that glassy Tuesday session. Don’t hold your breath for the first week—it’s mostly a wash—but the second week cleans right up.

Rusty.
