San Antonio, located in south-central Texas near the edge of the Hill Country, experiences a warm subtropical climate that supports year-round pollen production. The city's proximity to dense forests of mountain cedar and abundant oak trees makes it one of the most challenging cities in the United States for allergy sufferers, consistently ranking in the top 10 for spring allergies and experiencing the infamous "cedar fever" phenomenon. This guide covers San Antonio's main pollen types, seasonal patterns, peak allergy months, and effective management strategies using the Pollen Count & Alerts App.
Understanding Pollen Count in San Antonio
Pollen count measures the concentration of pollen grains per cubic meter of air, with readings reported daily by STAAMP Research, San Antonio's official National Allergy Bureau-accredited monitoring station. When pollen counts are high, allergy sufferers typically experience nasal congestion, sneezing, itchy and watery eyes, sore throat, headache, and fatigue. In San Antonio, extremely high mountain cedar concentrations can cause reactions even in individuals without diagnosed allergies.
San Antonio's Most Significant Pollen Allergens
San Antonio's allergy profile is dominated by several highly allergenic pollen types, with mountain cedar being the most notorious. Recent climate trends show warming temperatures are extending reproductive cycles and increasing overall pollen production, while earlier blooming and longer pollen seasons have been documented across the region.
- Mountain Cedar (Ashe Juniper): The dominant allergen producing over 35 million tons of pollen from Hill Country forests, causing the severe "cedar fever" phenomenon from December through February with peak intensity in mid-January
- Oak Pollen: A major spring allergen that coats cars and surfaces with visible yellow dust from mid-February through mid-May, peaking in late March to early April
- Ragweed Pollen: The primary fall allergen causing symptoms from August through November, with peak concentrations occurring in September and October
- Grass Pollen: Summer allergens including Bermuda, Bahia, and Johnson grass produce elevated counts from May through August, peaking in July and August
San Antonio's location along the I-35 corridor acts as a pollen superhighway, with strong cold fronts carrying mountain cedar pollen up to 200 miles from the Edwards Plateau and Hill Country. Climate change and drought conditions are causing earlier blooming cycles and extended allergy seasons, contributing to San Antonio's ranking as the 5th most challenging U.S. city for spring allergies in 2022.
Seasonal Pollen Patterns Throughout the Year
San Antonio experiences distinct pollen seasons that overlap throughout the year, creating nearly continuous allergen exposure for sensitive individuals.
- Winter (December to February): Dominated by mountain cedar pollen released from late December through mid-February, with peak "cedar fever" intensity in mid-January causing severe flu-like symptoms
- Spring (March to May): Characterized by high oak, elm, pecan, and ash tree pollen, with peak allergy conditions occurring in late March and early April when oak pollen is most abundant
- Summer (June to August): Grass pollen season featuring Bermuda, Bahia, Johnson, timothy, and ryegrass, with peak counts in July and August and generally lower overall pollen levels than other seasons
- Fall (September to November): Marked by ragweed, pigweed, and fall elm pollen, with peak concentrations in September and October ranking San Antonio as the 4th worst U.S. city for fall allergy sufferers in 2018
