Alright folks, Rusty here with the skinny on what's coming our way. It’s a bit of a slow couple of weeks, so don't get your hopes too high.
First off, we’ve got a big pulse of energy roaring in on Monday, July 6th. We’re talking a solid 8ft swell from the SSE, but unfortunately, the wind is howling cross-onshore, trashing the surface and making it a choppy, lumpy mess. That size (over 8ft) is for experienced surfers only anyway, but with the wind in that direction, the quality is just garbage. This big energy (between 1370 and 2445) hangs around through Wednesday, but it’s the same story—big, angry, and blown out. At Little Austi and Main Beach, this setup might actually be better for the kite crowd.
Now for the one real standout, the day to mark on your calendar: Saturday, July 11th. We finally catch a break. The swell drops to a friendly 4ft from the SE, which is a nice, manageable size. But the real beauty is the wind—light offshore from the WNW. The report says "expect good surf conditions," and with a moderate wave energy (262), it’ll be clean, fun, and have a bit of push. The crowds are listed as "sometimes," so you might just score a quiet session. The water temp is about what you’d expect for this time of year.
After that, it’s a long, slow fade. From Sunday the 12th right through to the 20th, we are looking at a big gap with hardly any rideable swell. There’s a tiny tease on Thursday the 16th with a very long period (19 seconds) 1ft swell and glassy conditions, but it’s just too weak (124) to do much with. That long period stuff is better for a point break or a reef, not so much a beach. The second week is pretty much a write-off. So, save your energy for that Saturday the 11th—it’s your best shot.
Rusty.
