Austin, TX Grass Pollen
Grass pollen in Austin usually peaks around May through June, reaching 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.
Bermuda and other warm-season grasses keep Austin's counts up from May into June, then ease off in the July heat before a smaller fall bump.

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