Where is Louisiana?

Louisiana (the 18th state that was admitted to the union on April 30, 1812) is located in the Deep South region of the South Central USA. It shares its borders with Mississippi to the east, Texas to the west and Arkansas to the north. To its south, the Gulf of Mexico is present.

What is the Geography of Louisiana?

The US state of Louisiana is spread across a total area of 52,069.13 sq. mi (135,382 sq. km), making it the 31st largest state in the United States. The land area of Louisiana is 43,601 sq. mi (112,927 sq. km) and the water area of the state is 8,283 sq. mi (21,455 sq. km). Water covers a large part of the state, which is around 17.5% of the total area.

Louisiana is around 380 mi (611.6 km) long and 130 mi (209.2 km) wide. The state has a coastline that is approximately 7,721 mi (12,425.8 km) long. However, rising sea level and increasing human activity is heavily degrading the coastline, at the extent of 25 sq mi (64.7 sq km) per year.

The state’s mean elevation is just 100 ft (30.5 m) above sea level. While Driskill Mountain at 535 ft (163.1 m) above sea level is the highest elevation point, 8 ft (2.4 m) “below” sea level in New Orleans is the lowest elevation point. Some of the significant mountains in Louisiana are Driskill Mountain, Gentry Hill, Jordan Mountain, Delaney Mount, Mossy Hill, Duncan Hill, Bull Hill, Giddens Hill, Eagle Hill and Negro Foot Hill.

The major rivers in the state are Mississippi River, Red River, Ouachita River, Sabine River, Pearl River, Bayou Bartholomew, Bayou Macon, Boeuf River, Calcasieu River and Tensas River. Lake Pontchartrain, Toledo Bend Reservoir, Lake Claiborne, Caddo Lake, Cross Lake, and Lake Kincaid are some of the major lakes.

This South Central state in the US has three distinct geographic land regions: East Gulf Coastal Plain, Mississippi Alluvial Plain, and West Gulf Coastal Plain.

The East Gulf Coastal Plain is located north of Lake Pontchartrain and to the east of the Mississippi River. It is a low land and marshlands are located near the river. As you move towards the north, the land rises to form rolling hills.

The second major geographical region is the Mississippi Alluvial Plain, which is located along the Mississippi River. While it starts in Arkansas in the north, it stretches to the Gulf of Mexico in the south. Ridges and hollows are the characteristic features of this geographical region. The “frontlands” (the fields that are situated on the top of the ridges along the Mississippi River) slopes down to the “backlands” (the area of land comprising clay and slit).

At the mouth of the Mississippi River, the Mississippi Delta is located. This delta is spread across an area of around 13,000 sq mi (33,669.8 sq km), which occupies about 1/4th of Louisiana. Mostly silt deposit is found in the Mississippi Delta, making it the most fertile land in the state.

The third important region in Louisiana is the West Gulf Coastal Plain, which is located in the west of the Mississippi Alluvial Plain. Barrier beaches are found along the gulf in the southern part. Marshes extending to 20 mi (32.2 km) north into Louisiana’s interior are located behind the barrier beaches along the gulf. The Louisiana Prairies (situated to the north of the marshlands) has a gently rolling landscape that rises gradually towards Arkansas in the north.

What is the Climate of Louisiana?

The climate of Louisiana is subtropical, thanks to its location along the Gulf of Mexico. Continental weather patterns also affect the vast Mississippi-Missouri river valley that is located around half the way between the Pacific Ocean and the Atlantic Ocean.
While the winters are mild, the summers are hot and humid.

However, frequent afternoon thundershowers temper the hot and humid weather in summer. Tropical storms and hurricanes pass through Louisiana during June-November.

The average annual temperature in the extreme north is 64 °F (18 °C). However, at the mouth of the Mississippi River, the average temperature hovers around 71 °F (21 °C). The monthly average temperature ranges from the high of 82 °F (28 °C) in July to a low of 50 °F (10 °C) in January.

Humidity is more intense than the heat in the subtropical climates. The average level of rainfall in the state ranges within 45 inches (1,140 mm) at Shreveport to over 56 inches (1,420 mm) at New Orleans. The average number of days in the growing season revolves within 220-to-320 days.
