Las Vegas, NV Juniper Pollen

Juniper pollen in Las Vegas usually peaks around February to April, reaching Moderate at its worst. Las Vegas planted so many olive and mulberry trees that their pollen became a public health problem, and Clark County banned new ones in 1991. Those trees still drive a heavy spring, with juniper in winter and grass into early summer.

Juniper pollen turns up in the mild desert winter, an early start to the Las Vegas tree season.

Managing juniper season in Las Vegas

If juniper is your trigger, start a daily antihistamine like cetirizine (Zyrtec) or loratadine (Claritin) a week or two before the February to April 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 Nevada can test whether juniper is really what you react to and talk through longer-term options like allergy shots.
