Now that's freezing

Posted: Updated:

Everyone has their own idea on what a freezing temperature is. Some people think it is "freezing" when they have to wear a jacket when they head out the door, others think it is when they can see their breath. The literal definition of a freezing temperature is when the air temperature reaches 32 degrees (or below), in other words, the temperatures at which water freezes.

In Southern Arizona, we keep track of when many cities hit the first freezing temperature of the year. So far, Tucson has not dipped below the 32° mark. On average Tucson reaches freezing for the first time on November 24th. The earliest the Tucson International Airport ever reached freezing was October 16th back in 1899! Many cities have already seen nights cold enough to pass the freezing Mark. Willcox hit freezing on October 25th, while Nogales, Douglas, Bisbee, Sierra Vista, Safford, and Tombstone all recorded their first freezing night last night (November 11th).

If you are not a fan of the cold, we also keep track of the latest some cities have hit freezing. The latest Tucson has ever gone before hitting 32° (or lower) was January 25th in 1978.

This next week we will warm back into the 70s during the day and 40s at night, so at least we will push off the freezing morning in Tucson a few more days!
