Long-term development of temperatures from 1988 - 2020

In contrast to single record values, a long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would give a falsified result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would already decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and falsifies the average again. The subsequent long-term development was therefore reduced to only 1 measuring points in order to have actually comparable data over as long a period as possible.

In the years 1988 to 2020 there were only these 1 weather stations in the whole country, which reported continuous temperature values (Norfolk Island). From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was 2020 with 24.2 °C. 1994 was the coldest month with an average temperature of 14.8 °C.

The average annual temperature was about 19.1 °C in the years after 1988 and about 19.7 °C in the last years before 2020. It has therefore increased only slightly by about 0.6 °C over the past 33 years. This trend only applies to the selected 1 weather stations on Norfolk Island. A considerably more comprehensive evaluation of the global warming has been provided separately.
