Fall Freeze Data For Many New Mexico Cities

The growing season across New Mexico varies considerably, due to the large variation in elevation. The lowest elevations are near 3,000 feet in the far southeast plains (around Jal), while the highest elevations tower above 13,000 feet (Wheeler Peak). The San Juan, Rio Grande, Canadian and Pecos river valleys also affect the growing season, as cold air sinks into the valleys on many fall and winter nights. See the graphic example farther below. To complicate matters, there is often what is called a 'thermal belt' above the cold pool of air in the valley. This is a layer of air that is considerably warmer than farther below in the valley. This thermal belt is usually located near the mid slope of a mountain or more gently sloping terrain. A good example exists around Albuquerque. At the valley floor, temperatures can be ten or more degrees colder than at the Albuquerque Sunport, while the Sunport will generally be several degrees warmer than the foothills.

A 'freeze' is considered to have occurred whenever the temperature drops to 32 degrees or lower. A growing season is calculated by taking the number of days between the last freeze in the spring and the first freeze in the fall. However, plants or crops do not necessarily follow this rule. A low temperature of 31 or 32 degrees for a short period of time, say less than two hours, probably will not harm most plants or crops. But if the temperature drops to 28 or 29 degrees for a few hours, most vegetation will be damaged. As a side note, frost can form when a solid surface (like a car or plants) is in contact with the air and the solid surface's temperature drops to 32 degrees or colder. The extent of the frost depends on how much moisture is in the air. If the temperature is above 32 degrees and there is enough moisture in the air, then dew (a liquid) forms instead of frost (a solid).
