The line graph and bar chart provide a comparison of average daily temperatures and the mean number of rainy days in two Australian cities, namely Brisbane and Canberra, over the course of a year.
Overall, both cities experience a V-shaped temperature pattern, with figures declining towards the middle of the year before recovering. In terms of rainfall, the two cities display divergent patterns: Brisbane is wettest at the start and end of the year, whereas Canberra sees a higher frequency of rain during the winter months. Notably, Brisbane remains warmer than Canberra throughout the entire period.
At the beginning of the year, Canberra exhibited a wider temperature fluctuation than its counterpart. In January, while both cities shared a similar maximum temperature of approximately 27°C, Canberra’s minimum was much lower at 13°C, compared to 21°C in Brisbane. This gap in temperature narrowed slightly as autumn approached in April. Regarding precipitation, Brisbane started the year as the much wetter city, recording 13 to 14 rainy days per month in the first quarter, which was nearly double the figures for Canberra (7 to 8 days).
Moving on to the middle of the year, both cities recorded their lowest temperatures in June and July. During this winter period, Canberra was significantly colder than Brisbane, with its minimum temperature dropping to a mere 1°C, compared to 10°C in Brisbane. Interestingly, there was a stark contrast in rainfall patterns during these cooler months. While Brisbane’s rainy days reached a yearly low of only 7 days per month, Canberra experienced its wettest period with 10 days of rainfall consistently from June to August. Towards the end of the year, temperatures in both cities recovered to their initial levels, and Brisbane once again surpassed Canberra in terms of rainfall, peaking at 12 days in December.
