The Lowdown

Alright, Rusty here, let's talk about Scorpion Bay.

It’s looking like a slow start, with a couple of days of knee-high, ordinary surf to kick things off. The real story this fortnight is the slow build toward a fantastic window late in the first week and into the second. We've got a classic SSW groundswell pattern setting up, and the longer period stuff is going to make this point break absolutely peel.

Thursday the 20th and Friday the 21st are pretty forgettable. You're looking at waves around 2ft to 3ft from the SSW. The wind is offshore, but the energy is weak – around 230-247 (combined swell energy). It's surfable, but nothing to get excited about.

Things start to look up Saturday the 22nd. Still small at 2ft, but the period bumps to 15 seconds, and we see a jump in energy to 285 (moderate). A light offshore wind on Saturday morning will have it glassy and clean, making it a decent little session for a longboard. That afternoon we get a risk of thunderstorms, but still offshore wind.

We hit a bit of a lull on Sunday the 23rd morning with a cross-onshore wind making a mess of the 3ft swell. That afternoon, however, a 2ft SW swell with an *18-second period* rolls in. That's very long period groundswell, and with a light cross-off wind at 10 km/h, Scorpion Bay will turn those tiny waves into long, peeling lines. That afternoon is a real hidden gem for a very specific time.

Now, the standout window starts Monday the 26th of August. From the 25th (Tuesday) through the 29th (Saturday), we get a proper run. On the 25th, we see the swell jump to 5ft from the SSW with a 12-second period. The combined energy hits 649 (strong) Tuesday afternoon, and with a 20 km/h offshore wind, this is the first real session of the trip. The wave quality will be excellent.

Wednesday the 26th holds with 4ft swell and strong energy (577), and the wind stays light offshore. Thursday the 27th is another solid day of 4ft swell.

The absolute standout is Friday the 28th of August. The morning starts with 3ft, but the period is a dreamy 17 seconds. By the afternoon, we're looking at 4ft from the SSW at 18 seconds, with a 15 km/h offshore wind and the combined swell energy is a massive 1149 (very strong). This is going to be one of those days that lives in your memory. The point will be firing with long, fast, grinding walls. It's an advanced wave at that size with that period, but for the crew that knows this place, it's perfection. Crowds? Scorpion Bay is always busy for these windows.

The 29th keeps the quality high with a 5ft SSW swell at 16 seconds and a strong offshore wind (1047 energy) in the morning. The 30th and 31st have smaller but still clean surf in the mornings before the wind shifts on the 31st afternoon.

After the 1st of September, the outlook gets a little more questionable with strong onshore winds developing from the ESE on the 2nd and 3rd, making it look much better for kiting than surfing as the swell gets chopped up. By the 4th, there's a lot of energy around (1228) but the wind is cross-on, so the quality drops right off.

So, the call is clear: Friday the 28th of August is the day. Mark it. Don't miss it. For the rest, the mornings on the 26th, 27th, 29th, and 30th are your next best bets.

Rusty.
