Climatological Frost/Freeze Information (With Latest Maps)

  Climatological Frost/Freeze Information

With the onset of Fall, the growing season eventually comes to an end with a return to cooler weather and the occurrence of frost, and freezing temperatures. 

When you look at historical freeze data (32 degrees or lower), there is a tremendous variation from year-to-year and between any given location in south central Nebraska and north central Kansas. Last year, the fall of 2009 saw fairly normal first freeze dates beginning on September 29, 2009 across portions of south central Nebraska, to October 10, 2009 in north central Kansas.  Average freeze dates for the 30 year period (1980-2009) range from September 27 in the Greeley, Nebraska area, to October 16th in the Beloit and Plainville, KS locations. 

Here are the definitions of frost, freeze, and hard freeze: 

Frost occurs when there is a solid deposition of water vapor from the air. Frost will form when solid surfaces are cooled below the dew point. An air temperature range of 33 to 36 degrees is needed for frost formation. Minor damage is possible to some plants.  
 

A Freeze occurs when the air temperature drops to 32 degrees. A freeze will result in significant damage to many unprotected plants, especially if the temperature remains at the freezing mark for a few hours.


A Hard Freeze occurs when the air temperature reaches 28 degrees. The growing season is considered to have all but ended when the temperatures drops to 28 degrees.  The range of dates for a hard freeze is from the 1st through the 3rd week of October (on average) for south central Nebraska and north central Kansas.
