The climate of Illinois (United
States of America)
Illinois is one of the states located in the northern part of the
United States of America. Illinois is one of the most densely
populated states in the country. Illinois also has one of the best
economies in the country. This is because many industrial regions can
be found in Illinois as well as a lot of agriculture. Many raw
materials can be found here as well such as petroleum, coal and wood.
Illinois has a hilly landscape, its highest point is located at an
altitude of only 376 meters above sea level. Illinois is located in
the interior on Lake Michigan. The largest city in the state is
located here which is Chicago. Illinois has a warm continental climate
with much more erratic weather than you would expect. Long term
average figures are only a guideline in which big fluctuations may be
possible. During the winter it may get extremely cold with subzero
temperatures during the day. During the summer temperatures may rise
well above the average of 29-32 degrees Celsius (84-90 degrees
Fahrenheit). Illinois is located in the so called Tornado Alley, a
large area with a high risk of tropical storms and hurricanes. On
average about 35 tornadoes can be recorded annually in Illinois.
Although the number of tornadoes and the wind speeds they reach are
not above average, tornadoes often cause more damage in Illinois than
in other places. Because Illinois is densely populated chances of
damage are higher.
