The provided charts compare the mean highest and lowest temperatures per day in Celsius degrees recorded in Brisbane and Canberra while delineating the typical number of days with precipitation.
Overall, both Australian cities typically see dips in temperature mid-year and recover by the end of the year then remain relatively warmer for the first quarter of the year. However, Brisbane is generally warmer, yet its temperature gap between the hottest and the coldest points is more volatile in the first quarter, while that in Canberra tends to be thinner during summer and more dispersed in winter and spring. Notably, Brisbane usually witnesses more rainfall in most months, in which Canberra only dominates for a few months mid-year.
Regarding average daily temperature, Brisbane’s hottest point starts at around 28 Celsius degrees and peaks at 30 degrees by February. After a sharp decrease to almost 20 degrees, the figure fluctuates here until July and commences to improve gradually back to almost 30 in December. Over the same period, Canberra’s hottest point experiences a smoother downward sloping change, plunging from approximately 27 degrees in January to almost 10 degrees in July and slowly bounces back to the initial point in December.
Although the minimum temperature in Brisbane remains relatively predictable, ranging around 20 degrees for most months and only reaching 10 degrees mid-year, the temperature gap is remarkably narrower in January and April, yet this gap slowly stabilizes at 10 degrees onwards. Meanwhile, that for Canberra, following a similar pattern, is noticeably lower, reaching around 12 degrees on hotter months while almost touching zero degrees in May and June.
With respect to days with precipitation, the figures for Brisbane nearly double those for Canberra from December to April, with the former ranging from 12 to 14 days while the latter remains around seven to eight days. Upon May, the gap narrows to ten and seven, respectively, before Canberra surpasses the counterpart, peaking at ten days on average for the three subsequent months. Over the same period, Brisbane witnesses months with lowest rainfall (7 days), which lasts until September and steadily recovers to 12 days by the end of the year. Canberra, on the other hand, varies from ten days to eight days, but is unevenly distributed across the four last months.
