As such there are a number of both ,modern and historical cultures with varied number of seasons. The northern hemisphere experiences more direct sunlight during May, June and July as the hemisphere faces the sun. The same is true of the southern hemisphere in November, December and January. It is earth’s axial tilt that causes the sun to be higher in the sky during the summer months, which inceases the solar flux. However due to seasonal lag, June, July and August are the warmest months in the northern hemisphere. While December, January and February are the warmest months in the southern hemosphere. In temperate and sub-polar regions four seasons based on the Gregorian calendar are generally recognized spring, summer, autumn and winter. .
