30 Biggest Cities in Louisiana Ranked by Daily Mean Temperature
I created the table below by researching data for the most populous municipalities in Louisiana. When I couldn’t find data for a given city, I moved on to another. While the list includes 30 cities, some of the bigger cities may be missing because there was no data for them. Please check the closest geographically city then.
