If you live in coastal South Florida, cold weather is usually not much of a problem regarding growing palm trees. However, if you live in an area where cold temperatures are a much greater concern it mandates that you know which palms to buy. It's a must that you know how cold it actually gets in your aea.
The limiting factor in the successful growing of palms is the degree of cold weather that any given palm species will see during the winter. So, if you don't want to grow a palm for a few years just to see it severely damaged or killed by one cold night, you must determine how cold does it get on the coldest night during the winter. And, is that low value typical of most winters. Regarding palms, you don't need to know the "temperature zone", but the actual low temperature "number". This is because, within any zone, there are variations and microclimates.
There are methods and instruments you can use to determine the lowest temperature during a winter, but they only record the current winter. That doesn't do you much good if you want to plant some palms now. If you are new to an area, the best thing you can do is to ask some locals about low temperatures. Or, go to a local nursery - one that's been around for a while - and ask the owner or an employee who's worked there for a long time. You can also look around in your neighborhood and see what other people have successfully grown. All of these things let you know about your weather and what palm trees might grow in your area.
