Local Environmental Conditions
Built-up land makes up around 50% of the area near this location in Houston, with a good deal of woodland. Close to a stream or river, riverside vegetation contributes to what is in the air. Woodland on all sides makes trees an important local pollen source. Grass pollen is significant here, and plantain contributes weed pollen.
Tree pollen comes first, peaking in early spring. Grass pollen follows, peaking in mid-spring and easing off by mid-fall. Plantain flowers through much of the warmer half of the year. Rain is heaviest in spring, often giving short breaks from high pollen levels. Actual levels on any given day depend on the weather, with dry, breezy days the worst and wet days the mildest.

Does pollen in Houston come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Houston based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Houston, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
