In my experience the weather in this part of Australia (Victoria) can be sometimes incredible. Often after a period of very hot days we get a ‘southerly change’. This is in reality quite a shock – it can go from 40 C to 20 C (104 F to 68 F) in literally 30 minutes…the wind changes from a hot northerly to a cool southerly and the winds are often very strong. This happened on Monday and flattened the long grass in this paddock. The prevailing winds are north/south as you can see from the way this tree has grown, bent from south winds.
