Winter usually lasts from November through April. The temperature is usually below 40 degrees Fahrenheit (4.4 degrees Celsius). Because the DeKalb area is flat, wind is a major consideration. In the winter months, the low temperature becomes more dangerous because of the wind.
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.
If you're coming to NIU from a tropical climate, we recommend that you purchase your winter clothes here after you arrive.
