Summer Solstice

21st June is the longest day in the Northern Hemisphere, technically this day is referred to as Summer solstice. The Earth receives a greater amount of energy from the Sun on this day.

Solstice

  • Solstice means “sun stands still” in Latin.
  • During the solstice, the Earth’s axis — around which the planet spins, completing one turn each day — is tilted in a way that the North Pole is tipped towards the Sun and the South Pole is away from it.

More Summer Solstice, 21st June

  • The day is referred to as the summer solstice, and it occurs when the Sun is directly over the Tropic of Cancer, or more specifically right over 23.5 degrees north latitude.
  • According to NASA, the amount of incoming energy the Earth received from the Sun on this day is 30 percent higher at the North Pole than at the Equator.

Length Of Day – Uneven Heating Of Earth’s Surface

  • The tilt of the Earth in combination with the latitude of location affects the length of the day.
  • Those living on the equator have 12 hours of daylight and 12 hours of darkness every day of the year.
  • At the North Pole, one would have 6 months of constant daylight from spring to fall. 
    • One would encounter 24 hours of night for six months from fall to spring.
  • Varying amounts of heat: With more time to absorb energy from the Sun, the Earth retains varying amounts of heat
  • This uneven heating of the Earth’s surface has an effect on the seasons.
    • Long Day = Warmer
    • Equal Day = Moderate
    • Short Day = Colder
