Warm and wet are the essential characteristics of the climate of Baton Rouge, which experiences rain showers all year round, high temperatures and humidity during summer, and generally warm, sunny winter weather. There is an element of unpredictability in the climate of Baton Rouge, however, and cold spells have been experienced in winter, even the odd unexpected snowfall. The best time to travel to Baton Rouge is between February and April, when the weather is usually fine and the heat and humidity not at peak levels.

Public transport options include buses, which go all over the city but run infrequently, and the Capitol Park Trolley, which provides free service around the downtown area. Renting a car is perhaps the best option; the minimum age is usually 25, although some agencies only require drivers to be 21 years of age, a surcharge may be added. A valid driver's license, passport and major credit card are also required. Keep in mind that Baton Rouge is a much busier place than it once was. When Hurricane Katrina hit nearby New Orleans, many people were evacuated to Baton Rouge, and many have stayed. Many roads and highways now experience significant congestion regardless of the time of day.

English is the most common language but Spanish is often spoken in south-western states.
