What is the Summer Solstice?
The summer solstice is an astronomical phenomenon that occurs when one of the Earth’s poles has its maximum tilt toward the sun. This event results in the longest day and the shortest night of the year, making it a pivotal moment in the solar calendar. The term "solstice" derives from the Latin words "sol" (sun) and "sistere" (to stand still), reflecting the sun's apparent position at noon during the solstice, which remains relatively unchanged for several days.
During the summer solstice, the sun travels its highest path across the sky, leading to increased solar radiation and warmer temperatures. This period is crucial for many ecosystems as it signifies a time of growth and reproduction.
