ROCHESTER, N.Y. (WHEC) --
How cold does it have to get before your school closes? In preparation of the another frigid morning, we have the information your school superintendent uses to make that decision.
Currently, all districts in Monroe County follow guidelines set by the health department to close school when there is a wind chill of -25°F .
The Monroe County Health Department writes a letter to all local school superintendents with the department's recommendation on when schools should consider closing.
The letter says "frostbite can occur on exposed skin in about 30 minutes at wind chills of -25°F. At wind chills of -40°F, frostbite can affect exposed skin in as little as 10 minutes."
The letter continues "taking everything into consideration, to lessen the risk of cold injury to students, I recommend that you use a wind chill of about -25°F as the temperature to consider closing schools."

So how do you determine what the wind chill will be and the danger of frostbite? The National Weather Service has a chart that is also used by local schools. For instance, if the temperature is -5* and the wind is blowing at 15MPH, the wind chill is -26*. And that would meet the County Health Director's recommendation to consider closing school.
