The Lowdown
Alright, let’s talk about what’s happening at Little Austi and Main Beach. Right now, it’s totally flat. Thursday the 30th and Friday the 31st of July, you’re looking at nothing – 0.3 ft of swell, combined energy of just 5. It’s a real bummer to start.
Things pick up on Saturday the 1st of August. The morning is still a bit messy, but the afternoon turns glassy. We get a 5 ft SSE swell with a 9-second period, combined energy of 551. That’s moderate power, and with the wind dropping to glass, it’s going to be clean. That’s your first real shot.
Sunday the 2nd of August morning is the one to circle. A clean 6 ft swell from the SE, 12-second period, and 908 units of energy. The wind is light offshore from the NNW, so the waves will be clean and well-shaped. This is the best morning of the first week. The afternoon gets a bit choppy, so get out early.
There’s a lull from Monday afternoon through the end of the first week, with small waves and poor conditions.
Now, the second week. Monday the 10th of August morning is glassy with a 5 ft NE swell, combined energy of 370. The period is short at 7 seconds, so it’ll be a bit soft, but that glassy surface makes it fun for the intermediate crew.
But the absolute standout of the whole 16 days is Wednesday the 12th of August morning. We’re looking at a 6 ft ESE swell, 11-second period, combined energy of 863. The wind is a clean offshore from the WSW. This is where the reef setup at Little Austi will really come alive. The swell direction is perfect for the optimum ENE exposure, and with that long period, it’s going to have real power and shape. The afternoon bumps up to 7 ft, but the wind turns onshore, so the morning is the sweet spot.
This break is a beach and reef setup, and it’s fairly consistent but expect crowds, especially for that Wednesday morning. The water temp is about average for this time of year.
For beginners, stick to Saturday the 1st afternoon and Monday the 10th morning – the swell stays under 5 ft and the conditions are clean. Anything over 8 ft, like that Wednesday afternoon, is for the experts only.
So, bottom line: Sunday the 2nd of August morning is your first week winner, and Wednesday the 12th of August morning is the absolute king of the forecast. Don’t miss it.
