Gunnamatta Beach Surf Forecast and Surf Report

Alright crew, Rusty here, and we’re looking at a sixteen-day stretch for Gunnamatta Beach. It’s a real mixed bag for a classic beachbreak. There are some serious pulses of energy coming through, but the wind is the real make-or-break factor.

We start off with a pulse right now on September 13th. There's a big, clean, long-period groundswell from the southwest, pushing 5 ft to 5 ft, but it’s directly under a fresh northerly offshore breeze. The conditions will be clean, but the wave comment flags a marginal state, likely due to tide. The combined energy is high (1136), but it's not quite firing.

Monday the 14th and Tuesday the 15th look pretty ordinary. The swell drops off, and the wind swings onshore, making for poor, choppy conditions. By Tuesday arvo, we get a big jump in size to 12 ft (4246 energy) but it’s with a strong onshore wind – that’s just a washing machine.

The mid-week gets even bigger. Wednesday the 16th sees solid 10 ft to 12 ft swell from the south-west with very high energy (over 8683), but it's cross-onshore and lumpy. That’s not for paddling; honestly, a setup like that with strong wind is more interesting for kite surfing.

We get a bit of a breather Thursday the 17th. The swell drops to a still-chunky 8 ft, but the wind goes light and onshore from the SSW. The energy is still high (2180). It’s marked as marginal. Friday the 18th is a similar story with moderate cross-shore winds.

Saturday the 19th shows some promise with a clean, offshore breeze from the NNW, but the swell is only around 5 ft to 6 ft and a bit inconsistent. It's a fallback day.

Now, the true standout is Monday the 21st of September. The morning looks absolute magic. Glassy conditions, a light southwest wind, and a solid 8 ft groundswell from the southwest. The report says "excellent surf conditions for experienced surfers." This is the window. It’s still a powerful 8 ft with 1903 energy, so it’s for the advanced crew. The crowd profile says they are often here, so expect company. The afternoon gets bigger to 10 ft, which is getting into expert-only territory.

Tuesday the 22nd is another major standout for the big-wave brigade. We’re looking at a long-period 12 ft swell from the southwest in the morning with a light offshore ESE breeze. The energy is massive (6452). The report flags it as too big for this break, which confirms it’s only for expert chargers. The afternoon holds size, but a cross-shore wind will chop it up.

Wednesday the 23rd offers another window. A 7 ft morning groundswell with light, clean offshore breezes. It’s back to "excellent" territory for experienced surfers.

Thursday the 24th brings the biggest deep water pulse of the whole outlook. We have a very long-period (19 seconds) 10 ft swell from the southwest. The energy reading is massive (6917). The wind is light and offshore. Again, this is a "too big" call for the break, meaning it’s a truly serious day, and that long period might make it a bit straight and fat on a beach. It’s a huge day for experts only.

The last few days from the 25th to the 28th see the swell back down, but the wind and energy are messy. The 27th and 28th have huge swell (around 15 ft) again, but with poor winds or mixed conditions.

To sum it up: If you’re an experienced surfer, the standout is the morning of Monday the 21st of September. It’s the first real window of clean, powerful conditions without it being overwhelming. If you are an expert, the morning of Tuesday the 22nd and Thursday the 24th are your monster-swell targets, but treat the long period with respect at this beach.

This is Rusty, signing off.
