Atchafalaya Basin. The wetlands of Louisiana are water-saturated coastal and swamp regions of southern Louisiana, often called "Bayou".. The Louisiana coastal zone stretches from the border of Texas to the Mississippi line [1] and comprises two wetland-dominated ecosystems, the Deltaic Plain of the Mississippi River (unit 1, 2, and 3) and the closely linked Chenier Plain (unit 4).

Similarly to the rest of Louisiana, the Sound experiences a semitropical climate. [1] The average water temperatures range from 70˚F to 84˚F (21–29°C) by month and the humidity ranges between 73% and 84%. Due to the humidity, clouds often form overhead, reducing the amount of daily sunlight that the area receives to as little as 4 hours. [2]
Louisiana has been losing about 25 square miles of land per year in recent decades". [2] The EPA further reports: "If temperatures continue to warm, sea level is likely to rise one to three feet during the next century. Rising sea level has the same effect as sinking land, so changing climate is likely to accelerate coastal erosion and land loss.
This decrease in flow across the floodplain, in conjunction with high organic deposition from trees and floating vegetation and high water temperature, has resulted in large areas of low-dissolved oxygen water. Where once the water was black (1850), the water became brown (1927). Where the water was formerly brown (1927), it is now black (2009 ...
Much of the Gulf Coast has a summer precipitation maximum, with July or August commonly the wettest month due to the combination of frequent summer thunderstorms produced by relentless heat and humidity, and tropical weather systems, including tropical depressions, tropical storms, and hurricanes, while winter and early spring rainfall also can ...
If peak storm surge and high tide happen together, water levels from Burns Point to Port Fourchon, Louisiana, could rise between 5 and 10 feet above ground levels, the hurricane center said.
Summers in southern Louisiana have high temperatures from June through September averaging 90 °F (32 °C) or more, and overnight lows averaging above 70 °F (21 °C). At times, temperatures in the 90s °F (32–37 °C), combined with dew points in the upper 70s °F (24–26 °C), create sensible temperatures over 120 °F (49 °C). The humid ...
