In general, the graph depicts varying temperature averages in London, New York, and Sydney from January until December. For cities located in the northern hemisphere of the globe, i. e. London and New York, the temperatures start rising in a similar fashion until they peak in mid-July with approximately 23 and 30 degrees celcius, respectively. From this point the decline sets in and the weather becomes older in New York and Sydney, although the former experiences a faster return into winter conditions with average temperatures of 5 degrees in December. On the flipside, summer weather comes along faster and more intense with 2535 hours of sunshine, compared to 1180 hours in London. Sydney, finally, reaches almost the same number with 2473 hours of warming light per year. However, the temperature cycle in Australia, as it is situated on the southern hemisphere, is inherently different. From mid-September to April temperatures stay just over 20 degrees and reach their minimum in July with almost 16 degrees celcius. This shows that the weather development follows an inverted pattern.
