We are going for a record stretch of days above 40c here in Adelaide, last couple of days have been 45 -46. Over night we have been dropping to a cool low of 35.
They always take temperatures in the shade for some stupid reason, in my back yard it was 58c yesterday.
I have air con already but it is strugging to keep up, its alright early in the day but once the sun starts beating on the front of the house at lunch time things start to heat up.
