Memphis, TN Ragweed Pollen
Ragweed pollen in Memphis usually peaks around September, reaching Very High at its worst. Memphis sits in the humid Mid-South, where a warm, wet climate makes for a heavy, drawn-out allergy year: maple and oak in spring, grass through summer, and a long ragweed fall along the Mississippi.
Ragweed is the fall story, peaking in September; the Mississippi River bottoms give it plenty of ground.

Ragweed pollen by month in Memphis
How ragweed usually runs across the year. The current month is outlined.
Managing ragweed season in Memphis
If ragweed is your trigger, start a daily antihistamine like cetirizine (Zyrtec) or loratadine (Claritin) a week or two before the September peak, rather than waiting for symptoms. Keep windows closed on high-count mornings, shower and change clothes after time outside, and run the AC on recirculate in the car.
When symptoms don't ease with over-the-counter medicine, an allergist in Tennessee can test whether ragweed is really what you react to and talk through longer-term options like allergy shots.
