Once in around 20 years or more we get temperatures that high! 1975 and 76 were over 30C, again in 2006. I don't recall anything like it in between but there might have been an occasional 25C.
Our current temps.. it can be the same for the whole of summer! We rarely get hard freezes, it's been as low as -20C in the early 1980's and again near that in 2010/11 but usually no lower than -5 to -7C.
