Southern Cross 12074 maximum temperature audit

At Southern Cross 12074 from 1 January 1907 to September 1972, whole .0 Fahrenheit degrees represented 33% of all maximum temperatures recorded and .5 Fahrenheit degrees represented 6.2% of all maximum temperatures recorded.

1907-1972 represented 65.7% of the time span and had 46.9% of .0C and 17.3% of .5C maximum temperatures within the entire temperature record.

From September 1 1972 to 29 November 2007, maximum temperature recordings of .0 Celsius degrees represented 21% of the total and .5C recordings represented 12.5% of the total of all fractions since 1972. Together, .0C and .5C represented 33.6% of all maximum temperatures recorded since metrication.

Southern Cross 12074 minimum temperature audit

At Southern Cross 12074 from 1 January 1907 to September 1972, whole .0 Fahrenheit degrees represented 36.7% of all minimum temperatures recorded and .5 Fahrenheit degrees represented 5% of all minimum temperatures recorded.

1907-1972 represented 65.7% of the time span and had 46.3% of .0C and 12.2% of .5C minimum temperatures within the entire temperature record.

From September 1 1972 to 29 November 2007, minimum temperature recordings of .0 Celsius degrees represented 22.3% of the total and .5C recordings represented 14.1% of the total of all fractions since 1972. Together, .0C and .5C represented 36.4% of all minimum temperatures recorded since metrication.
