College Station sits in the Brazos Valley of east-central Texas, where a humid subtropical climate and long growing season create a nearly year-round allergy calendar with few genuine breaks.
The allergy year kicks off dramatically in winter with mountain cedar (Ashe juniper) pollen drifting in from the Hill Country between December and February, followed by a heavy spring tree season dominated by oak, pecan, elm, ash, mulberry, and hackberry from March through April—oak pollen in particular blankets surfaces across the region.
As trees taper, grass pollen takes over from late April through summer, with Bermuda, Johnson, Bahia, and Timothy grasses driving symptoms well into September thanks to repeated mowing cycles and warm nights.
Fall belongs to weeds, especially ragweed, which peaks from late August through October, alongside pigweed, lamb's quarters, and careless weed.
Overlap is common: spring trees and early grasses frequently collide in April, while late-summer grasses and ragweed compound symptoms in September.
The area's persistent humidity also fuels year-round outdoor and indoor mold (Alternaria, Cladosporium), and dust from dry spells plus agricultural activity add further irritation.
Overall, College Station's allergy profile is defined by prolonged exposure, high humidity-driven mold, and heavy oak, grass, and ragweed loads.
