1. Summer (/ˈ sʌmər/ SU-mər) is the warmest of the
four temperate seasons,
between springand autumn. At the
summer solstice, the days are longest and the
nights are shortest, with day-length decreasing as
the season progresses after the solstice. The date
of the beginning of summer varies according to
climate, culture, and tradition, but when it is
summer in the northern hemisphere it iswinter in
the southern hemisphere, and vice versa.

Sun Safety
Solstice: This comes from two words, sol, meaning “sun,” and sistere, meaning “to stand.” In the Northern
Hemisphere, the summer solstice is when the sun “stands” at its most northern position in the sky. The winter
solstice is when the sun “stands” at its most southern position.
Fun Fact:
The hottest temperature ever recorded in the United States was on July 10, 1913 when Death Valley, California
reached 134 degrees F.
The temperature reached 136 degrees in El Azizia, Libya on September 13, 1922, setting the world record for
heat.
Heat
It's summer and the heat is on. The summer solstice in the Northern Hemisphere, or top half of
Earth, is around June 21. That's when the sun reaches its most northern point over our planet. The
days around June 20 are the longest of the year, and the rays from the sun beat almost directly down
on use and warm us up.
Longest, Not Hottest
You might think that the longest days of the year would be the hottest. But they are not. The hottest
weather, on average, comes about a month after the summer solstice. This is because the amount of
heat from the sun continues to accumulate during the long hot days, and the short nights don't allow
as much heat to leave. The days start to cool down only after the days grow short enough to allow
more heat to leave Earth's surface than arrives.
