High pollen levels in Atlanta, Georgia, has been particularly noticeable since the start of spring. The Weather Channel has advised that tree pollen will remain very high through April 3. Avoid outdoor activity when the highest counts are highest, limiting it to mid-morning on dry, windy days and reducing indoor exposure to pollen by keeping windows closed during peak pollen times. Experts advise people with predictable seasonal allergies to start using antihistamines or nasal corticosteroids before peak season.
