September 20. September in Adelaide is the last month of the year in which we hope to receive a reasonable amount of rain. Our mean rainfall for the first month of spring is 2 inches or 50 ml. Bear in mind that our annual rainfall is 525ml. (21 inches). Some say South Australia is the driest state in the driest continent in the world. It sure feels like that at the moment.
This year, our winter rainfall was only 60 % of the average. You can see this in the hardness of the soil when you dig. Summer lies ahead with those challenging weeks of furiously high temperatures and no rain.
I returned from our recent trip up north acutely aware of the devastation that the drought has had on the countryside. So I started watching the 28-day forecast of possible rain that is produced by Elders Weather – hoping for rain for the stations we had returned from. They get their rain from monsoonal troughs arriving from the north. And in the last few days, one arrived.
Witchelina, Farina and the Marree area received close to 100ml of rain (4 inches). The Flinders Ranges recieved a little less. Flood warnings were broadcast with images of swollen creeks. A godsend. Our ABC news was full of the wonder of this record downpour, as farmers rejoiced.
So we waited in Adelaide, hoping for the meagre 20 mm (1 inch) that was forecast for last Thursday, Friday and Saturday. The clouds were dark but no rain fell … a few showers passed south over Kangaroo Island. I started watering the garden again.
Today, Sunday, the skies were full of sound and fury and once more in anticipation I examined the local radar – a narrow band of orange, red and black approached us from the west. We got some rain! Only 5ml over half an hour, but so very welcome.
Later, I walked out in the dark to set our two feral cat traps (yes, we are trapping feral cats with help from our council) and the bush seemed to be singing.
