How Long It Lasts
At low levels, the most durable snowfall occurred in the town of Greenbushes in 1900 when snow covered the ground for four hours. However, at low levels, snow rarely lasts more than half an hour before melting. This is due to temperatures at ground level seldom being low enough to sustain snow for long; even on the coldest of cold days, maximum temperatures rarely fail to reach 8°C in inland towns. Also, snowfalls are inevitably followed by rain, which quickly washes away what little cover there may have been. Many reports of snowfalls involve snow falling but melting upon contact with the ground
