I'm at about 42 N. Latitude, I looked up where 42 S would be cuz maybe the climates are similar, and that would put it at about Echuca or Bendigo, Victoria in Australia. Basically we can get a frost as early as 3rd week of September, but the killing frost is usually around October 5. Spring is a little more unpredictable, the last frost being anytime in May, about 2nd week on average. well our weather is famous for being unpredictable, summers can be cool and damp, cool and dry, or hot and humid or dry... usually it varies, wet spells then near drought then hot and humid then cool, you get the picture! Normal is 25-35 C, average about 28 I guess and like 4 or 5 dry days followed by a rainy one. Hope that helps! PEACE
