What is summer?
Summer brings a lot of
sunlight, so flowers are
in full bloom .
Summer is one of the four seasons of the year.
It always comes after spring. The seasons repeat
the same pattern each year. Spring comes before
summer, summer changes to fall, fall changes to
winter, and winter turns back to spring.
Feeling hot
Summer is the hottest season of the year. People
usually spend a lot of time outside. When people go
outside, they must wear light clothing, such as shorts
and T-shirts. What do you wear when you go outside
to play on a hot summer day?
Why do we have summer?
It takes Earth one year to travel around the Sun. Earth
is tilted slightly as its moving. This causes parts of Earth
to receive more sunlight at different times of the year.
The different amounts of sunlight changes the seasons.
In fall, North
America begins
to tilt away from
the Sun.
In summer, North
America is tilted
toward the Sun.
In winter,
North America
is tilted away
from the Sun.
In spring, North
America begins to
tilt toward the Sun.

America
Tilted toward
During summer in North America, the northern parts
of Earth are tilted toward the Sun. They are getting hot
temperatures and more daylight hours. The southern
parts, such as South America, are tilted away from the
Sun. This means they are getting cold temperatures and
less hours of daylight.
What do you
t h i n k ?
Hot weather and
plenty of sunshine are
signs that summer has
arrived. Can you think
of some other signs
of summer?
When is summer?
In North America, the first day of summer is in
June. All the seasons, including summer, last for
three months. During summer, the Sun rises early
and sets late, so the days are long. Warm nights
are a sign that summer has arrived.
