Spring's Harris County Texas suburban setting features loblolly pine, live oak, and cedar elm as the main tree pollen sources, with exposure varying between the greener wooded residential neighborhoods of the Spring Creek Greenway and the more built-up commercial corridors along FM 1960. The Spring Creek corridor is a particularly significant local source, while the surrounding Piney Woods transitional landscape creates distinct woodland-urban pollen gradients throughout the season.

Which pollen types are currently active in Spring?

When is pollen season in Spring?
Spring's Houston suburban setting in Texas produces a season opening in late January with cedar and oak before grass from surrounding Gulf Coast farmland peaks through April and May. Mugwort and nettle extend exposure into September, while the flat Gulf Coastal plain allows pollen to disperse widely and the warm, humid Gulf Coast climate supports an extended spring pollen season throughout.
How often is the Spring pollen forecast updated?

The Spring pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Spring 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 Spring 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 Spring, 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.
