The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Little Austi and Main Beach.
For the next couple of weeks, it’s a real mixed bag. We’ve got a bit of a slow start, but there’s a solid pulse of energy brewing for the second week that looks like it could be the main event. The water temp is sitting right where it should be for this time of year, so no surprises there.
The first real chance to get wet is Wednesday, July 22nd. Little Austi and Main Beach is waking up with a clean 4 ft swell from the ENE, with a 10-second period generating moderate wave energy (238). The wind is a light cross-offshore, which is a beauty. It's not a massive day, but it's clean, surfable, and honestly, that’s a nice start. The afternoon holds the same quality, so you can get a session in after work.
Thursday, July 23rd drops off quick. The swell drops to 3 ft, and while the wind is still cross-off, it’s blowing a fresh 12 mph. The energy drops right off (94), and the conditions are just average. Not worth getting excited about.
From Friday, July 24th all the way through to Monday, August 3rd we hit a real dry spell. That’s over a week of tiny, weak swell with nothing doing. The wave heights barely hit 1 ft, and the energy levels are in the single digits. There’s a glassy morning on the 27th and again on the 1st of August, but with hardly any swell, you’d be better off with a longboard or a day off. The wind is mostly clean, but there just isn't any power in the water.
Now, here’s the standout. Look towards Tuesday, August 4th. The morning sees a bump to 4 ft from the east with light wind, and the energy is building (179). But the real highlight is the Tuesday afternoon. We get a solid 5 ft from the SSE. The period is short at 7 seconds, but the combined energy is pumping at 370. The wind is light and cross-off, keeping it clean. This is the best on offer in the whole window. It’s a proper thumping beach break, but that size might be a bit much for beginners. More experienced crew will be all over it.
Wednesday, August 5th keeps the good run going. Morning sees a 5 ft swell from the SE with a clean offshore breeze. The energy is still strong (279). It’s another quality day, but the short period at 7 seconds means those waves will be a bit fat and crumbly, better for a bit of a grovel than a steep drop.
Thursday, August 6th the swell backs off a little to 3 ft from the ENE, but the energy is still moderate (233). The wind picks up a bit, so it’s not as clean as the previous days. Worth a look if you’re desperate for a wave, but the real magic was Tuesday and Wednesday.
So, bottom line: the first week is a write-off. Wait for Tuesday, August 4th afternoon for the best chance at a proper session. Get it while it’s clean.
Rusty.
