The summer solstice for 2018 is tomorrow (June 21st) and is the longest day of the year, north of the equator.
The exact time of the summer solstice is 6:07 a.m. when the sun is directly over the Tropic of Cancer.
In the Northern Hemisphere, peak sunlight usually occurs on June 20, 21 or 22 of any given year. December 21, 22 or 23 is the winter solstice.
During the summer solstice the further north you are the more sunlight you'll see, and we're pretty far north here in Maine so we should see a lot of daylight. if you live near the Arctic Circle the sun never really sets during the solstice.
According to vox.com the summer solstice is considered the longest day of the year but this June 21st, 2018 isn't the longest day in Earth's history. That distinction goes to the year 1912. Taking into consideration many factors, 1912 was the longest longest period of daylight in the Northern Hemisphere. and that same year (1912) was the longest winter solstice with the longest night we've seen.
