Merredin 10092 maximum temperature audit

At Merredin 10092 from 1 January 1966 to September 1972, whole .0 Fahrenheit degrees represented 26.5% of all maximum temperatures recorded and .5 Fahrenheit degrees represented 5.5% of all maximum temperatures recorded.

1966-1972 represented 15.2% of the time span and had 6.8% of .0C and 5.1% of .5C maximum temperatures within the entire temperature record.

From 1972-2011, maximum temperature recordings of .0 Celsius degrees represented 15.6% of the total and .5C recordings represented 11.3% of the total of all fractions since 1972. Together, .0C and .5C represented 26.9% of all maximum temperatures recorded since metrication.

Merredin 10092 minimum temperature audit

At Merredin 10092 from 1 January 1966 to September 1972, whole .0 Fahrenheit degrees represented 27.4% of all minimum temperatures recorded and .5 Fahrenheit degrees represented 4.6% of all minimum temperatures recorded.

1966-1972 represented 15.2% of the time span and had 9.1% of .0C and 4.5% of .5C minimum temperatures within the entire temperature record.

From 1972-2011, minimum temperature recordings of .0 Celsius degrees represented 12% of the total and .5C recordings represented 11% of the total of all fractions since 1972. Together, .0C and .5C represented 23.1% of all minimum temperatures recorded since metrication.
