In which month is the highest precipitation?

The answer on this question depends not only on season but on region. For example in Africa the highest precipitation is in August and March. In northern part of Australia this period is during summer months and in southern Australia the highest precipitation is usually seen during winter and spring. In different parts of Europe the wet season can be seen between March and November or from October through March. In fact most of the countries have the highest precipitation season from June to mid-October.
