Preliminary Climate (F6)
 
Note: Data for a full month is usually available on the first day of the following month, and is obtained by "Version 1" above. If the data was edited/quality controlled and re-issued on a later date (somewhat rare), it is acquired by "Version 2" above. The latter version queries a very large file, so results may be slow. All data is preliminary, and may contain errors. Final and certified climate data is available at the National Centers for Environmental Information (NCEI) in Asheville, NC (https://www.ncei.noaa.gov).

First Freeze (Fall)  |  Last Freeze (Spring)
In the pictures: Average first freeze dates in the fall and last freeze dates in the spring across Arkansas (based on 1991-2020 normals).
 

In Arkansas, freezes typically occur by the last week in October across northern and western sections of the state (Ozark and Ouachita Mountains). Elsewhere, freezes tend to hold off until the first couple of weeks in November. In the spring, the last freeze usually happens by mid-March in the southeast. For the remainder of the region, freezes usually linger into April and sometimes into early May in parts of the north.

Please Note: The dates shown are based on climatological normals, with a temperature of 36° for frost and 32° for a freeze. There is at least a 50 percent probability that a first (F) or last (L) Frost/Freeze will occur on these dates. Probabilities go up to 90 percent for a FFrost/FFreeze two weeks later and a LFrost/LFreeze two weeks prior. Probabilities go down to 10 percent for a FFrost/Freeze two weeks prior and a LFrost/LFreeze two weeks later. The dates are courtesy of the National Climatic Data Center.
