Austin, TX Ragweed Pollen
Ragweed pollen in Austin usually peaks around September through October, reaching Very High at its worst. Austin sits on the eastern edge of the Texas Hill Country, and that geography gives it an allergy calendar unlike the rest of Texas: mountain cedar in the dead of winter, oak and grass through spring, and ragweed in the fall.
Ragweed closes out the Austin allergy year. Counts climb after Labor Day, peak through September and October, and fade with the first real cool-down.

Ragweed pollen by month in Austin
How ragweed usually runs across the year. The current month is outlined.
Managing ragweed season in Austin
If ragweed is your trigger, start a daily antihistamine like cetirizine (Zyrtec) or loratadine (Claritin) a week or two before the September through October 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 Texas can test whether ragweed is really what you react to and talk through longer-term options like allergy shots.
