The question
The line graph shows the average temperatures in two cities in six months of the year.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.
What to notice before you write
Both lines follow the same shape: they rise to a peak in July and fall afterwards. The key comparison is that City Y is warmer in every month, by between 8 and 12 degrees. Mention the highest and lowest points of each line and the size of the gap.
Band 7 sample report
The line graph compares average temperatures in two cities across six months of the year.
Overall, both cities experienced their warmest weather in July, and City Y was consistently warmer than City X in every month shown.
In January, the average temperature in City X was only 2°C, compared with 14°C in City Y. Temperatures in both cities then rose steadily until the summer. City X reached a peak of 24°C in July, while City Y recorded a much higher maximum of 31°C in the same month.
After July, the figures fell in both cities. By November, City X had cooled to 8°C and City Y to 19°C. The gap between the two cities was widest in January, at 12 degrees, and narrowest in May and July, at 7 degrees.
The pattern also shows that the temperature in City Y never fell below 14°C, while City X dropped to as low as 2°C at the start of the year, which indicates much milder winters in City Y overall.
