Summer Solstice

Summer Solstice is the longest day (and shortest night) of the year in the Northern Hemisphere. It is observed on June 21.

What does it mean?

• The solstice occurs when the sun is directly over the Tropic of Cancer or 23.5 N latitude.
• Since earth s axis is tilted at an angle of 23.5 deg, varying amounts of sunlight reach different regions during its year-long orbit around the Sun.
• On June 21st the North Pole is tipped more towards the Sun than on any other day of the year.
• But this does not mean more heat or that the Earth is any closer to the Sun, per common misconceptions.
• Solstices happen twice each year Summer solstice for the Northern Hemisphere and Winter solstice for the Southern Hemisphere when the sun is directly over the Tropic of Capricorn or 23.5 S latitude.
