The table illustrates the average monthly rainfall, measured in millimeters, across four cities: London, Mumbai, Sydney, and Cairo, over a 13-year period from 2008 to 2020.
Overall, Mumbai experiences exceptionally high rainfall during its monsoon season, contrasting sharply with Cairo, which receives almost no rain throughout the year. London's rainfall is relatively consistent, while Sydney shows moderate levels with some monthly variation.

However, this changes dramatically during the monsoon months, peaking at 668 mm in July and remaining very high in August (529 mm) and September (312 mm). Sydney, in contrast, has a more even distribution, with its highest figures in March (131 mm) and June (133 mm), and the lowest in September (71 mm).
London maintains a relatively steady rainfall total each month, generally staying between 36 mm and 54 mm, with the highest amounts seen in November (53 mm) and December (54 mm).
