Summer Solstice

In the Northern Hemisphere, the summer solstice occurs on June 21 with the longest period of daylight.
On June 21^st, the Northern Hemisphere is tilted towards the sun and the rays of the sun fall directly on the Tropic of Cancer.
As a consequence, areas exposed to sun rays receive extra heat and the areas near the poles get less heat (as the rays of the sun are slanting).
As a large area of the Northern Hemisphere is receiving light from the sun, it is summer in the regions north of the equator and longest day & the shortest night at these places occur on 21^st June.
