NOAA makes weather records from the Florida stations available to download for free. Out of the 1,700+ stations, 358 contain at least some temperature data. If one were to download all of these records, import them into a database, and use some crafty SQL queries to generate sheets for each of the impact freezes it would provide a really good side-by-side resource to compare the microclimates in each region of Florida.
That is exactly what has been done with the 0000_202011040720_F_SQL_v2.xlsx spreadsheet attached to this post. Each tab in the spreadsheet contains records for one of our unfortunate cold events. The records come sorted first by the TAG column, which represents one of the areas in the pictures and is defined by a set of latitude and longitude boundaries. A second sort is by the station name alphabetically. This gives you a region of weather stations sorted alphabetically that allows you to see the temperatures in the region beside each other.
The lists are able to be filtered or sorted in any way you choose, so if you are only interested in weather stations in a particular region or set of regions, this is easily accomplished. For easy viewing, the rows for each region alternate in shading. This is easy to remove or change if you wish.
If you would like to see the boundaries of a region, the weather stations used with a link to their corresponding Weather Underground station, or a listing of the freezes and some commentary lifted from Florida Citrus Mutual’s website, or a description of the station location, the 202007121300_NOAA_WeatherStations_TemperatureOnly.xlsx sheet will have a plethora of this information.
For anyone who likes to look at the various airport weather stations on Wunderground, 202004292350_AirportWeatherStations.xlsx will give you as complete listing of these stations as I could assemble.
Now for a description of the various TAGs:
PEN = Pensacola area
PAN - Panama City Area
TAL - Tallahassee Area
EPN - Eastern Panhandle
CNF - Central North Florida
JAX - Jacksonville area
NEF - Northeast Florida - Dayona + St. Augustine and surrounding area
NWC - Northwest Central Florida
SWC - Southwest Central Florida
NIC - North Inland Central Florida
SIC - South Inland Central Florida
ECF - East Central Florida
SWF - Southwest Florida
SEF - Southeast Florida
MUK - Miami and the Upper Keys
KEY - The South and Western Florida Keys

While perusing a few threads referencing the 1835 freeze, 1894-1895 freeze and the 1899 freeze, there were a few mentions of this book. There are used copies available on Amazon for less than $20 so I decided to order it. After reading it, I’d certainly recommend it. While the content is presented primarily from the point of view of someone interested in commercial citrus growing, the information about each of the events is certainly relevant to palm horticulture.
The book was a welcome relief from staring at a screen all day after working a job that typically centers around doing the same. There are a lot of references and to the small cities throughout the state since they are typically where citrus is grown, and the weather data is obviously of interest to anyone growing palms since the same freezes are typically what impacts what is long-term or bulletproof in an area.
The book contained weather records and quotes from the various growers as well as descriptions of the weather before and after the freeze. Some of the quotes are humorous in spite of the fact that these folks likely lost a lot of money due to these events. Almost all areas are at least represented in the weather records, including Key West in some cases.
There are actually two freezes from California noted in the book (1937 and 1990). In my case, the book does provide some weather readings from Lakeland City Hall rather than the airport, and has some weather readings from Bok Tower to compare to the Mammoth Grove area in Lake Wales to illustrate the difference elevation makes during a radiational event vs. an advective event. There is also information on a few of our early and late season frosts that have the potential to impact tropical plants and citrus alike. There book also covers an inverted freeze, where north and central Florida were not impacted as harshly as south Florida.
The cover photo actually came from our local newspaper, The Ledger.
As the book was released in 1997, the 1996 freeze is the last one fully covered. If you want a screen break and you like the data on the weather forums - give this one a read.
