Weather Reports for Mt. Lemmon

Anywhere from the bottom of the Santa Catalina Mountains to the top at Summerhaven/Mt. Lemmon, AZ winter weather can change within minutes, especially during the winter. A snow storm, white out or flooding can occur very quickly, especially above WIndy Point.

Check weather advisories and road conditions before you travel up the Catalina Highway to Mt. Lemmon, the Ski Valley, or other recreational areas in the Catalina Mountains.

Mt. Lemmon road closures are frequent in the winter. Many times, chains are required and vehicles will not be allowed beyond the park entrance point at the bottom of the Catalina Highway. The Catalina Highway has been closed off and on this year, not just because of snow, but because of traffic overload and gridlock.

There are some general conditions about Mt. Lemmon weather to observe:

  • temperatures are often 15-20 degrees F cooler on top of the mountain than at the Tucson level.
  • if there are clouds covering the mountain range, it is probably raining or snowing somewhere on the mountains. When it is raining in Tucson, it is probably snowing in the mountains.

If either of these conditions are evident, make preparations for difficult weather on the drive up the mountain.
