Climate trends at Atlanta (1930–2025)
Atlanta, home to over 5 million residents, is experiencing notable climate changes as observed at the Atlanta Hartsfield Jackson International Airport. The data spans from 1930 to 2025, revealing a warming trend that has significant implications for the region's climate and weather patterns.
From the first ten years of observation (1930–1939), the mean temperature was 16.81°C, while the last ten years (2016–2025) have seen a rise to 18.51°C, indicating a warming of 1.7°C over this period. This trend reflects broader changes in climate patterns, with implications for heat waves and drought risk in the future.
Trend Summary
Over the decades, Atlanta has shown a consistent increase in average temperatures. The mean temperature from 1961 to 1990 was 16.24°C, which increased to 17.41°C from 1991 to 2020. The most recent period from 2015 to 2024 has a mean temperature of 18.46°C. Notably, the warming since 1980 is approximately 1.66°C, with a trend of 0.389°C per decade since then.
Climate change impacts
As temperatures continue to rise, Atlanta may face increased risks of heat waves and droughts. These changes can affect water supply, agriculture, and overall public health. It is crucial to monitor these trends to adapt and mitigate potential impacts.
