New Orleans is in the southeastern part of Louisiana on the banks of the Mississippi River. It’s the largest city in Louisiana and known for its vibrant culture, music, food, architecture, and history. Much of the city is at or below sea level, so it’s surrounded by swamps and wetlands. That means the city experiences hot, humid summers and mild winters. Highs in the summer are around 90 degrees Fahrenheit, but the humidity makes it feel hotter.
