Katherine Aviation Museum is a weather station located 108 m above sea level, 3 km from Katherine. Its records go back to 1944: 23 years of temperature are available up to 2019, along with rainfall and a comparison with two reference normals. Closed series: the records of this station end in 2019. Over the whole series (23 years) the annual mean temperature there is 27.2 °C; the 1961–1990 and 1991–2020 reference periods are not documented well enough for a comparison. The warmest year of the series is 1998 (28.3 °C) and the coldest 2006 (26.2 °C). The last complete year, 2010, ranks 7 out of 23, from warmest to coldest. Over 1961–2019, the annual mean temperature changes by −0.14 °C per decade. The station ranks 227 out of 227 stations, from the fastest rise to the slowest.
