Band 8+: The graph and chart below give information on the average daily maximum and minimum temperatures in degrees Celsius and the average number of days with rainfall each month for two Australian cities. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

The line graph and bar chart illustrate the daily temperature, in degrees Celsius , and number of rainy days on average in the months of the year in two Australian cities; namely Brisbane and Canberra.

Overall, it can be seen that Brisbane experiences warmer temperature than Canberra over the year, while both two cities witness a similar temperature pattern in terms of maximum and minimum temperature. In addition, although Brisbane receives more total precipitation annually, there are more wet days in Canberra in the middle months of a year and the rainy days in Brisbane exceed those of Canberra in the remaining months.

At the beginning of the year, Brisbane’s maximum temperature is about 28°C and fluctuates between 20°C and 30°C during the first half of the year before surging to 29 in December. Meanwhile, Canberra’s maximum temperature is about 27°C in January and stays steady for a month. It then drops sharply to just below 10°C, before rising again to the starting level by December. A similar change, but a lesser extent, the minimum temperature in Brisbane witnesses a substantial decrease from roughly 22 in January to exactly 10 in July before increasing again to 20 in December. Although Canberra exhibits a similar temperature trend to Brisbane, its annual temperature figures are approximately half of those in Brisbane throughout a year. It sees a decrease from nearly 13 to about 2 at June and reaches the same level as at the beginning.

Regarding the bar graph, in the first five months of the year, Brisbane receives rain on about 10 to 14 days per month, while Canberra records around 7 or 8 wet days. In the next five months, the number of rainy days in Canberra remains stable at around 10 days, except for September, which records 8 days whereas, Brisbane experiences about 7 rainy days per month, with a slight increase to 8 days in October. In the last two months of the year, the figure for Brisbane shows an upward trend to 10 days in November and 12 days in December, while that for Canberra falls to just above 7 days in both months.
