Welcome to Adelaide.
Right now you'll probably be negotiating your way through customs or even out the doors into arrival crowd to see ......really heavy rain and grey skies.......
Don't worry in time you'll be like the rest of us, scanning the horizon waiting for cold fronts bringing the rain and absolutely loving driving down roads with brimming gutters spraying the pavement and hopefully no pedestrians with a massive side wash and hoping your cars electrics don't get too wet while doing it.
You will love the fact that within a few days of rain everything greens up a bit and the dust settles. Everything is freshened up.
You will love the fact that it can chuck it down so hard you have to slow down in traffic, have the wipers on max and maybe even pull over, but 20 mins later it's all gone.
The sun is never far away. Have a good rest and enjoy this great place.
