Summer:-)

Summer is a season that is astronomically defined as beginning around June 21, and ending around September 23 in the Northern Hemisphere. In the Southern Hemisphere, summer begins around December 21 and ends around March 21. Summer is defined by convention in meteorology as the whole months of June, July, and August, in the Northern Hemisphere, and the whole months of December, January, and February, in the Southern Hemisphere. The unofficial start of summer is a matter of convention: in Ireland it is as early as May 1, in many countries it is considered to be June 1, while in others it is as late as July 1. In general, seasonal changes occur earlier in coastal regions, so countries close to the oceans go for an earlier start to summer than inland ones. Summer is commonly viewed as the season with the longest (and warmest) days of the year, in which the daylight predominates, through varying degrees. In the northern latitudes, twilight is known to last at least an hour, sometimes leading to the famous white nights found in St. Petersburg and Scandinavia. It is also called the season of the midnight sun near the North Pole: in northern Norway, for instance.
