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.

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.
