Dallas, TX Grass Pollen
Grass pollen in Dallas usually peaks around May, reaching 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.
Grass pollen, mostly Bermuda and Johnson grass, runs from May into summer across North Texas lawns and roadsides.

Grass pollen by month in Dallas
How grass usually runs across the year. The current month is outlined.
Managing grass season in Dallas
If grass is your trigger, start a daily antihistamine like cetirizine (Zyrtec) or loratadine (Claritin) a week or two before the May 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.
