Summer Solstice (the first day of Summer) occurs on June 21st (for the Northern Hemisphere) and marks the point when the Sun appears farthest North.  At the Tropic of Cancer, the Sun will appear directly overhead at noon, and for most of the Northern Hemisphere, this will mark the longest day and the shortest night of the year.

Leo—whose arrival in the Eastern sky after Sunset marked the beginning of Spring—now exits in the Western sky, to be replaced by the Summer Triangle, an asterism of three stars, each from a different constellation.
This year, the brilliance of Venus, Mars and the just-past-First-Quarter Moon will make these stars seem less impressive, but they are some of the brightest in Earth's nighttime sky!
(Shown just after dark on the evening of June 21st for mid-Northern latitudes.)
