Phoenix, AZ Olive Pollen
Olive pollen in Phoenix usually peaks around April, reaching Very High at its worst. Phoenix has an allergy season that runs most of the year, driven by desert trees. Juniper and cypress start in winter, olive and mulberry peak in spring, and mesquite carries into early summer. These trees are so allergenic that the city restricts planting some of them.
Olive pollen is one of the most allergenic in the low desert, peaking in April. Phoenix bans the sale and planting of pollen-producing olive trees for exactly this reason.

Managing olive season in Phoenix
If olive is your trigger, start a daily antihistamine like cetirizine (Zyrtec) or loratadine (Claritin) a week or two before the 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 Arizona can test whether olive is really what you react to and talk through longer-term options like allergy shots.
