Summer is one of the four temperate seasons, typically characterized by warmer temperatures, longer daylight hours, and, in many regions, increased humidity. Occurring between spring and autumn, summer is associated with outdoor activities, vacations, and growth in agricultural crops. The start of summer varies by location: in the Northern Hemisphere, it begins around June 21, while in the Southern Hemisphere, it starts around December 21.
