BoM inspired media reports have widely spread the news that July 2013 in Melbourne was the warmest on record – most seem to be quoting daytime or maximum temperatures. here are a few articles –
Sydney Morning Herald -
Herald Sun -
ABC Online news -
I recall seeing an article that did mention the ever expanding Melbourne “urban heat island” (UHI). I quick check of July mean max for the following outer Melbourne weather stations indicates that outside the centre of Melbourne July in 1975 was warmer than July 2013. The record July 2013 warmth seems confined to the Melbourne UHI. Checking BoM data histories here and getting July 2013 data from here, select your station then follow the “Recents Months at…” links
Laverton RAAF BoM# 87031 – July 2013 15.3 – July 1975 15.7
Melbourne Airport BoM# 86282 – July 2013 14.7 – July 1975 15.1
Frankston BoM# 86079 – July 2013 14.2 – July 1975 14.8
Other Victorian stations to have July 1975 – or July from several other years, warmer than July 2013 are, Echuca Airport BoM# 80015, Rutherglen Research Station BoM# 82039, East Sale Airport BoM# 85072, Ouyen Post Office BoM# 76047, Omeo BoM# 83025.
Surely any balanced media release from the BoM should have recognized the restricted and man-driven nature of their Melbourne claim.
