Desert Allergen Calendar

Allergy symptoms in Tucson can change throughout the year depending on the season, weather, plants, and desert conditions. This page blends a simple seasonal allergy guide with the Arizona Desert allergen table so families can better understand common local triggers and the allergens included in the panel.

Why Desert Allergies Can Feel Year Round

Unlike some parts of the country that have one short allergy season, Tucson families may notice symptoms in more than one season. Trees often affect families most in late winter and spring, grasses can become stronger in late spring and summer, and weeds often pick up again in late summer and fall.

Indoor triggers such as pet dander, dust mites, and cockroach can also affect children throughout the year. This page is meant to be a simple seasonal guide, not a daily pollen report or a substitute for a provider review.

Helpful Note for Families

A child can still have allergy symptoms even if a lab result looks low or negative. Symptoms, timing, exposure, and medical history all matter when looking at allergies.

How to Read the Lab Result Table

The current Arizona Desert panel page lists each allergen with a numeric result and a class value. On that page, each listed allergen result is shown as less than 0.35 kU/L and Class 0, and the total IgE shown is 43 IU/mL.

  • Result: the numeric amount shown for each allergen
  • Class: the category level listed next to that allergen
  • Total IgE: a broader allergy related lab value that should be interpreted with symptoms and history

When to Talk With Your Pediatric Provider

  • Your child has frequent sneezing, itchy eyes, congestion, coughing, or seasonal flare ups
  • Symptoms seem to return during the same months each year
  • You are not sure whether symptoms are related to pollen, mold, indoor allergens, or something else
  • You want help understanding allergy testing in the context of your child’s symptoms
