Marana's Sonoran Desert suburban setting northwest of Tucson produces a season opening in January with palo verde and desert willow before grass from surrounding desert farmland peaks through March and April. Monsoon season from July through September brings a second grass and mugwort peak, while the hot desert climate concentrates the main spring season and the Santa Cruz River valley channels airflows.

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.

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 Marana, 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.
