What this tree pollen level means

Low risk. Keep windows open; consider allergy meds only if sensitive.

Enjoy outdoor activities.

Planted trees open in winter — the juniper family and ash first, mulberry at the heart of spring. This month sits outside the usual tree pollen window for the Desert Southwest pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Arizona allergy season guide singles out mulberry, ash and olive — planted trees, not wild desert flora.
