Oak Pollen
SevereHouston's live oaks produce enormous pollen loads from February through May. The city's warm, humid spring climate accelerates pollination and keeps pollen airborne longer than in drier Texas cities.
Ragweed
ModerateFall ragweed thrives in Houston's vacant lots, bayou corridors, and surrounding Gulf Coast prairies, producing an extended season fueled by warm autumn temperatures.
Bermuda Grass
ModerateBermuda grass dominates Houston's irrigated lawns and parks. The subtropical climate extends its pollination season well beyond what inland Texas cities experience.
Dust Mites
ModerateHouston's high year-round humidity creates ideal conditions for dust mite proliferation indoors, making it one of the worst U.S. cities for perennial indoor allergen exposure.

Why Allergies Are Worse in Houston
Houston's Gulf Coast location creates a year-round mold and allergen environment unlike any other Texas city. High humidity, low elevation near Galveston Bay, frequent flooding, and subtropical warmth sustain overlapping pollen and mold seasons throughout the year.
Gulf Coast Humidity
Houston averages 75%+ relative humidity year-round, creating ideal conditions for mold growth outdoors and indoors and keeping pollen grains airborne longer.
Low Elevation and Flooding
At just 50 feet above sea level, Houston's bayou system floods regularly, creating persistent moisture that drives mold spore counts to among the highest in the nation.
Subtropical Warmth
Houston's mild winters mean there is no hard freeze to reset allergen production. Mold, dust mites, and certain pollens persist through every month.
Urban Heat Island
Houston's massive urban footprint raises temperatures 5-8 degrees above surrounding areas, extending pollen seasons and intensifying summer allergen loads.
