Many people relocate to Arizona expecting to escape seasonal allergies. While the desert does lack many Eastern allergens like ragweed and mold, the Sonoran Desert has its own set of potent triggers that catch newcomers off guard — and affect long-time residents more than they realize.
Scottsdale's Allergy Calendar
Unlike regions with a single spring allergy season, Scottsdale has multiple peaks throughout the year:
- February through April — Tree pollen season. Mulberry, olive, ash, and mesquite trees are the primary offenders. Scottsdale's landscaping relies heavily on these species, and pollen counts can rival any Eastern city.
- April through June — Grass pollen. Bermuda grass, which covers most residential lawns and golf courses in the Valley, produces significant pollen through late spring.
- August through October — Weed pollen. Ragweed does grow in Arizona (despite the myth), and desert species like sagebrush and amaranth contribute to fall symptoms.
- Monsoon season (July through September) — Mold spores spike after desert rains. The combination of moisture and heat creates ideal conditions for mold growth.
Symptoms vs. a Cold
Allergies and upper respiratory infections share many symptoms — congestion, runny nose, sneezing, fatigue. The key differences: allergies cause itchy eyes and nose, last for weeks, and do not produce a fever. Colds typically resolve within 7 to 10 days and may include body aches and fever. If your "cold" lasts more than two weeks, it is likely allergies.
Effective Management Strategies
Over-the-counter antihistamines like cetirizine or loratadine are the first line of defense for most patients. Nasal corticosteroid sprays such as fluticasone are highly effective for congestion. Saline rinses help clear pollen from nasal passages after outdoor activity. For patients who do not respond to these measures, we can discuss prescription options or refer to an allergist for immunotherapy (allergy shots).
When to See Your Doctor
If over-the-counter remedies are not controlling your symptoms, if you are experiencing frequent sinus infections, or if allergies are interfering with your sleep or daily activities, schedule an appointment. We can develop a targeted treatment plan based on your specific triggers and severity.
