Rottnest Island 9193 maximum temperature audit

At Rottnest Island 9193 from 1 July 1983 to 31 December 2011, maximum temperature recordings of .0 Celsius degrees represented 10.3% of the total and .5C recordings represented 10.5% of the total of all fractions since 1972. Together, .0C and .5C represented 20.9% of all maximum temperatures recorded since 1 July 1983.

Rottnest Island Lighthouse 9038 maximum temperature audit

At Rottnest Island Lighthouse 9038 from 1 January 1965 to September 1972, whole .0 Fahrenheit degrees represented 16.6% of all maximum temperatures recorded and .5 Fahrenheit degrees represented 7.4% of all maximum temperatures recorded.

1965-1972 represented 25.8% of the time span and had 15.1% of .0C and 14.9% of .5C maximum temperatures within the entire temperature record.

From September 1 1972 to 16 December 1995, maximum temperature recordings of .0 Celsius degrees represented 13.3% of the total and .5C recordings represented 8.3% of the total of all fractions since 1972. Together, .0C and .5C represented 21.6% of all maximum temperatures recorded since metrication.
