Factors Influencing Humidity in Anniston

Anniston, located in northeastern Alabama, experiences significant humidity due to several geographic and climatic factors. Its proximity to the Gulf of Mexico and the Appalachian Mountains creates a favorable environment for moist air to enter the region. The prevailing southerly winds transport warm and humid air from the Gulf, which condenses as it rises over the mountains, resulting in high humidity levels. Additionally, Anniston’s relatively low elevation and its position within a valley trap moisture, preventing its dispersal and further contributing to the high humidity.

Seasonal Variations and Impact on Daily Life

Humidity in Anniston varies seasonally, with the highest levels occurring during the summer months. From May to September, average humidity ranges from 75% to 85%, creating an oppressive and uncomfortable atmosphere.

However, even during winter, there may be occasional periods of high humidity, particularly during transitions between weather systems.
