First freeze dates and Fall colors

Keep in mind various websites and books that show the average date of the first frost or freeze, often confuse the two.

Above dates are for the first 32F occurrence. However, FROST can occur with temps as high as 39/40F under the right conditions: clear sky and no wind for a sufficient number of hours with a mostly dry air mass with just enough low level moisture.

The OFFICIAL first freeze in the city is usually around November 13th. But that reflects the impact of the “urban heat island” so obviously the suburbs and rural areas away from the heat of the “concrete jungle” cool off faster and so get frost and freeze weeks earlier in many cases.

The average date of the first frosty 36F in the city is November 3rd, but that low of 36 has come as early as September 30, 1967 and as late as November 28, 1988.

Putting it simplistically, in much of Metro Atlanta the first freeze 32F happens sometime between October 16th and Halloween, 1-3 weeks later in the city and South Suburbs.

DATA FOR THE CITY OF ATLANTA:

The older maps shown above do not have the latest climate data input. The map below shows the first freeze is tending to come later in the most recent decade or two (updated through 2018) so for Hartsfield Airport it is November 13th:

ALLERGY WEATHER... if you suffer from allergies from mold, weeds, ragweed relief does not usually come until low temperatures drop below freezing.
