Goulburn winters are always quite cold, dead winters sometimes hitting minus temperatures. Coldest winter temp I have had In goulburn is about -12°C. There's always a chance of snow here and is sometimes for cast, but usually the snow misses goulburn and hits surrounding areas like Crookwell. I've lived in goulburn for about 3 years and it has snowed once for approximately 2 hours. But it was beautiful.
