Jim,I have attempted to compare the severe freezes experienced in RGV and Central Florida in 1983 and 1989 to get a perspective.This should provide some comparison between the nature of freezes experienced in these regions.

According to Rich Travis's article,The Dec. 1983 freeze saw below freezing temperatures for a minimum of 48 straight hours.The respective lows 0n Dec.24-26, of 24,21and 28.

In comparison,two locations in Central Florida during the 1983 freeze(Daytona and Bartow)had the following High/Low temperatures from Dec.24-27:Daytona-60/34;33/19;39/19;64/30; Bartow-71/50;51/24;47/22;66/39.

According to Rich Travis's article,the 1989 freeze in the RGV experienced atleast 54 straight hours below freezing.The low temperatures for Dec 22-24 were 24,17 and 18.

In Central Florida in 1989,Daytona and Bartow experienced the following High/Lows from Dec.22-26:Daytona-48/42;46/23;37/21;48/25 and 59/33; Bartow-50/46;46/33;43/22;63/44.

The greatest distinction between RGV and Central Florida was the lack of lengthty straight hours in Central Florida consecutively below freezing.I would attribute this to the effect of the Gulf,Ocean and large number of Lakes,which moderate temperatures.You can also see the relatively quick bounce in temperatures post freeze. Your comments.

The temps in the article are at 6 hour intervals, it actually did get above freezing on the 23rd of Dec, but only to 34F.  So, the time below freezing is probably about half of the 54 hours, going above freezing for a while, then back below freezing.  Either way, it was very cold obviously.  Looks like Central FL also barely got above freezing to 37F or so for Orlando, but did get a few degrees warmer than the RGV.  Not sure how much difference this made.  I don't know how much stock we can put into this freeze as it was probably a once in a lifetime occurence (or close to it).

Great work with the stats. I think the Tampa Airport weather station would probably compare favorably to Melbourne. There is no doubt S. Fla is the place on the US mainland for growing palms.

In comparing Texas with Florida the other component is rain. Must palms love water and so dryer and extreme summer heat is not a good thing when you are talking about growing roystonea or others. even the difference between Tampa and Miami in rainfall is important.
