Dallas, TX Ragweed Pollen
Ragweed pollen in Dallas usually peaks around September, reaching Very High at its worst. Dallas-Fort Worth catches a bit of everything Texas throws at it: cedar blown up from the Hill Country on north winds in winter, a strong oak and grass spring, and a long ragweed fall.
Ragweed is the fall story, climbing after mid-August and peaking in September across the Blackland Prairie around Dallas.

Ragweed pollen by month in Dallas
How ragweed usually runs across the year. The current month is outlined.
Managing ragweed season in Dallas
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 Texas can test whether ragweed is really what you react to and talk through longer-term options like allergy shots.
