The line graph illustrates the average monthly temperatures of the three major cities, while the table chart provides the data on the annual sunshine hours of those cities.
Overall, it can be clearly seen from the chart that Sydney shows relatively moderate temperature variation, whereas New York and London experience fluctuation of temperatures throughout the year. In terms of sunshine hours, New York records the highest figure among all cities; by contrast, London accounts for the lowest number of hours.
Looking closely at the line graph below, it is noticeable that the temperature of Sydney remained comparably steady throughout the year, starting at around 25 degrees in January and reaching the trough at 15 degrees in July andJuly, then gradually climbing to 25 degrees in December, recording only 10-degree difference in a year. By contrast, New York demonstrates a significant fluctuation, starting at almost 5 degrees, illustrating a sharp increase until reaching the peak at 30 degrees in July, then recording a significant fall to 5 degrees in December. This makes a 25-degree gap throughout the year, which is more than twice as much as that of Sydney. London showed a similar but less pronounced pattern, ranging from approximately 10 degrees in winter to almost 20 degrees in summer.
Regarding sunshine hours, New York accounted for the greatest figure with 2,535 hours, followed by Sydney at 2,473 hours with only 62-hour difference. On the other hand, London amounted to the least proportion with 1,180 hours, which is almost the half as much as New York.
