Well, if you really want one go ahead and buy one and then compare it's readings with what the closest weather station reports.
I have a thermometer, barometer and a rain gauge that I check daily. The first thing I do after I get out of bed is walk my dog, so I figure out the wind direction and approximate speed.
OR.... I can turn on my computer and get the same information before I walk the dog.
Weather reports were always an important part of my job when I was working, since I retired I still pay attention to them daily to decide if I should go hunting or fishing.
If you have children or grand kids, a weather station would be a good teaching tool to get them interested in physical science.
