Pollen counts in and around Atlanta follow strong seasonal patterns. The spring starts early in the southeast and in Atlanta we may see tree pollen as early as January. Tree pollen counts primarily from Oak and Birch tend to rise to peak levels by late March into mid-April and die down by late May. It should be noted however we sometimes will have tree pollen later in the summer or even September and this is called “Fall Elm.” Grass pollen starts in late May and is the primary allergen in the air during the summer months. It can cause very intense symptoms in certain people but is a much shorter season than tree pollen. Much like tree pollen It can cause troublesome ocular symptoms. Ragweed and other weed pollen (sage, pigweed, yellow dock) start in late August and are present until the first or second freeze in Georgia. You can usually see the tall ragweed plants growing on the side of the highway or in abandoned lots.
