Band 7+: The line graph below shows the average monthly temperatures in three major cities. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The line graph illustrates the mean temperature in Paris, Dubai and Sydney over the year.

Overall, two of three lines – namely, Paris and Dubai – had a positive correlation and reached their highest points in the median of the period with a little plato in Paris; while Sydney had the opposite trend and dipped in the middle.

Initially, the average temperature in Sydney was a top rate with about 24 degrees, the highest point. In July, it gradually decreased by approximately 10°C; then, it increased moderately till December. This line was completely opposite to others.

In January, roughly 19 degrees was an average in Dubai, while in Paris there was exactly 5°C, the lowest point out of all lines. In the next few months, both plots rose significantly till July to 35 in Dubai and 20 in Paris respectively. The latter levelled off for a month, whereas the former reached a peak at about 36°C in August. In the end, the temperature fell substantially to December by approximately 15 degrees in both cities.
