G’day, Rusty here. Let’s talk about what’s on offer for Little Austi and Main Beach.
The outlook is a bit of a mixed bag, to be honest. The first few days are a total loss with a big, messy 3 m SSE swell and strong cross-onshore wind making a real mess. The combined energy is sitting at 1534 (moderate to strong), but it’s not doing us any favours. We don’t see anything decent until Friday the 10th.
Friday afternoon is our real bright spot. The swell drops to 2 m from the SE with a 10-second period, and the wind goes totally glassy. That’s what we want to see. The water temp is 18°, which is average for the time of year. The combined energy is still moderate at 604, and it’ll be clean and lined up. This is the one to aim for.
Saturday the 11th keeps things going on a smaller scale. The morning brings 1 m from the SE with a light offshore from the NW, so clean conditions. The afternoon drops to 0.8 m from the ESE, but it stretches out to a 12-second period, a nice little groundswell, and clean on a cross-offshore breeze. Good fun.
Sunday the 12th still has a bit of life in the morning with 0.9 m from the ESE and a solid offshore from the NNW. Energy is weak at 217, but it’s clean.
Then it fades hard. From Monday the 13th onward, it’s tiny, weak, or completely flat. Energy readings drop to 17 and even 0. The wind cleans up, but there’s nothing to ride. A small bump around Friday the 17th shows 2 m, but it’s a short-period windswell with strong, messy wind. The whole second week is pretty much a washout.
So, the clear winner here is Friday afternoon, the 10th of July. That glassy, clean 2 m SE swell will be the best we get. Saturday the 11th is also worth a look for smaller, clean waves. The rest of the fortnight has a long flat spell from the 13th onward. It’s just one of those quiet runs.
Rusty.
