Summer or summertime is the hottest and brightest of the four temperate seasons, occurring after spring and before autumn. At or centred on the summer solstice, daylight hours are the longest and darkness hours are the shortest, with day length decreasing as the season progresses after the solstice.
The year is commonly divided into four seasons: spring, summer, fall (or autumn), and winter. Because we divide a year into 12 months, each season lasts about three months.
Summer provides the warmest weather of the four seasons as the days become hot and often dry (rainy in some Asian areas) with evenings remaining warm to hot depending on your location.
