Scottsdale Pollen Report
Scottsdale's desert landscaping is greener than the desert it replaced — and that's the allergy story. Fruitless mulberry and olive trees, planted across the city for decades, drive a hard spring season; Bermuda grass pollinates most of the year; and desert broom and ragweed close out the fall. Spring winds carry pollen across the entire Valley.

What drives allergies in Scottsdale
Trees: mulberry, olive, and mesquite (February – May)
Fruitless mulberry and olive — heavily planted across Scottsdale — are the Valley's signature spring allergens, with mesquite and palo verde contributing.
Grasses: Bermuda, nearly year-round (March – November)
Bermuda grass lawns and golf courses pollinate for most of the year in the warm desert climate.
Weeds: desert broom and ragweed (August – October)
Desert broom and ragweed fill the fall, with tumbleweed adding to windy-day counts.
Mold: low, monsoon-linked
The arid climate keeps mold modest, with spikes during the summer monsoon and in irrigated landscapes.

Frequently asked questions
What is the pollen count in Scottsdale today?
PollyMap publishes real, microscope-verified pollen counts for Scottsdale — measured from physical air samples. The latest report on this page shows current tree, grass, weed, and mold levels.
Is the pollen count high in Scottsdale right now?
Scottsdale's worst stretches are February–April (mulberry, olive), summer (Bermuda grass), and fall (desert broom, ragweed). The measured reports on this page show today's actual levels.
When is allergy season in Scottsdale?
Nearly year-round: mulberry and olive February–May, Bermuda grass most of the year, and desert weeds in the fall.
Why is the desert not allergy-free?
Decades of planting mulberry, olive, and Bermuda grass brought classic allergens to the desert — and the dry, windy climate spreads them efficiently.
Is pollen still bad in Scottsdale in the fall?
Yes. Scottsdale shares the Valley's fall ragweed season, which runs through October, and Bermuda grass keeps pollinating in the warm desert fall. The mild winter brings only a partial break.
