See ABC's news story about once-in-a-century heat wave in Melbourne - here. Seems I left for Europe just in time.
Three days in a row with temperatures close to 40 is something that makes one feel as if being in an oven. It is often worse to be inside of a house than outside. Unless it is air-conditioned, in which case it can be felt on the electricity bill, too.
As for the Europe - I traveled in a short-sleeved shirt. It is not that cold. The temperatures are above zero and I'm hoping to see some snow in the cities towards the end of the week.
