>For other uses, see Summer (disambiguation). Summer is a season, 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. In some Western countries, the first day of summer (in the Northern hemisphere) falls either on, or around, June 21 or on June 1 (the former is the astronomical start; the latter, the meteorological). 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.
