The provided graph illustrates the changes in temperature of three major cities throughout the year, while the table gives data about their annual sunshine duration. Overall, all cities experience a wild transition in average degree of heat. Additionally, London has the lowest total sunshine hours per year.
In terms of the line graph, in January, with nearly 25 degrees Celsius, Sydney is the hottest city, followed by London at about 8 degrees Celsius, which is 3 degrees higher than the figure for New York. In February, the heat level in London decreases slightly to just over 20 degrees Celsius, then rises again prior to falling steadily to its trough of 15 degrees Celsius in July. It subsequently increases until it is the same number from January before ending at over 25 degrees Celsius in December. However, the opposite trend is true for both London and New York. Over the next seven months, thermal level in these two areas increase sharply, with London reaching a peak of 30 degrees Celsius and New York 25 degrees Celsius. After peaking, the temperature in these cities drops rapidly to 10 degrees and 5 degrees Celsius, respectively.
In regard to the table, New York records 2535 hours of sunshine per year, which is more than twice as high as London’s 1158 hours. The figure for Sydney is modestly lower, at 2473 hours, making it the second highest sunshine duration.
