Long Term Temperature and Rainfall Patterns for Darwin (NT)


Maximum Temperatures have risen, fairly linearly, 2.5 to 3 °C over the last 80 years, starting from the late 1930s.

Minimum Temperatures show a very different pattern, only starting to rise in the late 1940s, reaching a peak in the late 1980s, just over only 1 °C higher. After the 1980s, they fell back half a degree but look to be possibly on the rise again.

Diurnal Ranges, given these patterns, were steady to around 1960, then rose half a degree over ten years but then fell back almost a degree to below the pre-1960 averages. Since 1986, the diurnal range has risen sharply one degree 

Rainfall at Queanbeyan has risen about 5% (572 to 609 mms), comparing 1870-1942 with 1943 to 2015. Ainslie seems to receive about 6% more rain than Queanbeyan. Given the overall variation, there is no significant change in rainfall over the whole period.
