Fall (Autumn) usually lasts from mid-September through early December with temperatures that are cool. You may need to wear a light jacket until mid-October when temperatures stay around 0º Celsius,(32º F). During the fall season, it is particularly important to take care of your health since the temperature often changes from days when some students will wear shorts to days when hats, coats and gloves are required. Autumn brings changes in the color of leaves to yellows, oranges and reds before they fall to the ground.

Winter weather begins in early December with temperatures often below 0º Celsius (32º F). January is the coldest month with many days of temperatures around -17.8º Celsius (0º F). Snow often covers the ground for long periods from December through mid-March but can start as early as November and last until April. During winter it is important to wear heavy coats, gloves, scarves, boots and hats to protect from the cold and wind. On the coldest of days, you may want to wear several layers of clothing. However, when dressed appropriately, walking in the snow can be a pleasurable experience.

Blizzards are a combination of heavy snow and strong winds. When the two are combined it is very difficult to see where you are going and the depth of the snow can be extraordinarily high. If at all possible, remain indoors and do not drive your car. Blizzards include snow, high winds, and cold. You often cannot see to drive in such conditions even if you can see out the window of your residence. Several inches can accumulate in a very short period of time causing streets or buildings to become blocked and closed temporarily.



Spring usually begins in mid-March and lasts through the end of May. The weather often changes between rainy, warm and sunny days but can also be as cool as 50º F.

Tornadoes: During the months of April, May and June the rapid changes in the weather may cause severe weather. Tornadoes do occur in Illinois. A tornado is a storm with very high winds that form a funnel cloud. These clouds form very rapidly and do great damage in a short period of time.

Tornado Watch: weather conditions are favorable for a tornado.

Tornado Warning: a tornado has been sighted in your area. Take cover immediately and listen to the local radio station to find out when the warning has expired.

Conditions to watch for: if a storm is developing with high, intense winds, lightning, and the weather seems threatening, listen to the local radio stations to find out if conditions are favorable for a tornado and what to do.




Summer begins in June and lasts through August. Temperatures can range 21º Celsius (70º F) to 35º Celsius (95º F). July and August have days when temperatures can be very high and there is high humidity, which often makes for an uncomfortable condition. Otherwise, summer days are generally pleasant and students enjoy being outside and can dress casually in shorts and sandals.
