Table - best surf conditions forecast for Little Austi and Main Beach over the next 16 days.
Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks at Little Austi and Main Beach.
The outlook starts with a bit of a messy picture. Right through the first few days, the wind is junk, coming straight from the south or southeast, which is cross-on at this spot. It’s making for choppy, bumpy conditions. The swell is there, around 5ft to 6ft from the SE, and the combined energy is moderate (502), but it’s just not clean. Not worth the paddle out.
We get a bit of a window on Saturday morning, July 11th. The wind swings northwest, going clean offshore, and the swell drops to 3ft from the ESE with a decent period of 12 seconds (407). That’s a proper groundswell. It won’t be big, but it’ll be glassy and clean. If you’re looking for a fun, small-wave board, that’s your moment. The afternoon stays clean with a cross-off breeze, but the swell is still small.
That’s where the run stops. From Sunday the 12th through the 16th, it’s flat or junky, with a big gap of no recommendations. The swell completely dies and the wind is a mess, either too strong or onshore. There’s nothing to get excited about there.
Now, look ahead to Friday the 17th of July. The swell is back, and it’s not messing around. We’re looking at 12ft from the ESE with a 12-second period (3332). That’s strong wave energy. The problem is the wind is still cross-on from the SSE, so it’s going to be a bit lumpy. This is big, powerful stuff – over 8ft – so it’s strictly for the experienced crew. Beginners, stay well clear.
The real standout, the one you want to circle on your calendar, is Sunday morning, July 19th. The wind goes clean offshore from the NNW, and the swell is a solid 8ft from the ESE with a 12-second period (1839). That’s a lot of energy, but with that offshore wind, the waves will be groomed, lined up, and proper. This is going to be excellent, but it’s big, so again, only for the experts. Expect crowds as it’s a known spot that can get busy.
The energy stays through the next week, but the wind isn't as perfect. The morning of Friday the 24th of July looks promising with a 6ft ESE swell and light offshore cross-off winds (528), which should give you some very good, clean waves. The weekend of the 25th and 26th also looks fun with clean, offshore wind and head-high swell.
So, to sum it up: the first few days are a write-off. The best bet by far is the morning of Sunday, July 19th, for the big, clean, powerful surf. It’s a long-range call, so keep an eye on it, but it’s got all the makings of a proper session. The water temp is sitting at 65°, which is about average for the time of year, so no need for a steamer just yet.
Stay stoked,
Rusty.
