Winter at NIU: Winter Usually last from November-April.  The temperature is usually below 40 degrees Fahrenheit (4.4 degrees Centigrade).

Strong Winds: Because the DeKalb area is flat, wind is a major consideration. In the winter months the low temperature becomes more dangerous, because of wind.

What to wear: If you dress appropriately for winter weather, you will be comfortable outdoors most of the time. For this reason you must have the right outer clothing, which includes; a hat (to cover your ears) and gloves to cover your hands. We also recommend that you have a heavy down coat and boots. For those of you coming to NIU from tropical climates, we recommend that you purchase your winter clothes here after you arrive. Please ask ISFO staff for more information about dressing appropriately for the winter.
