How to connect?

Leander's Texas Hill Country and Blackland Prairie setting features cedar, live oak, and elm as the main tree pollen sources, with exposure varying between the cedar-covered Hill Country terrain and the more built-up commercial corridors along Highway 183. The transition zone between Hill Country cedar and Blackland Prairie oak creates locally distinct pollen zones, while the San Gabriel River corridor provides green space and surrounding development expands rapidly across former prairie.

Grass from surrounding Texas farmland peaks through April and May before mugwort and nettle extend exposure into September. The mountain cedar season from December through February is one of the more intense and locally distinctive early-season pollen sources.
How often is the Leander pollen forecast updated?

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

Does pollen in Leander 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 Leander 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 Leander, 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.
