Local Environmental Conditions
Clinton sits on flat shortgrass plains along the Washita River in western Oklahoma, where the dominant vegetation is a mix of shortgrass prairie, wheat fields, and riverside cottonwood, shaping the local pollen profile across the seasons. Exposure varies with proximity to green space versus the more built-up parts of Clinton. None of this differs sharply from one year to the next barring unusual weather.
In Clinton, pollen season begins with maple and elm starting in March with oak taking the lead through April. Grass pollen builds through May and June, and ragweed extends the season into September. The continental Midwest climate produces a well-defined spring tree peak followed by a strong late-summer ragweed season.
