District 67 has a general guideline that students will go outside if the temperature is 15°F or higher. However, we also take other factors into account (wind chill, frostbite index, sunshine) in making the daily determination. If the sun is shining and the wind speed is low, we may send students out when the air temperature is slightly below 15°F. We also have the option of shortening the time students spend outside if needed. During winter months, always have your children dress for outdoor weather (coat, snow pants, gloves/mittens, hat, and snow boots).
