Local Environmental Conditions
Bisbee's setting on a mining town in the Mule Mountains near the Mexican border supports oak-juniper woodland, desert grassland, and agave and yucca as the leading local vegetation, all factoring into the pollen count through the year. Wind patterns across the area help determine how far pollen travels from these source plants. The mix of native and introduced species here is fairly typical for this part of the country.
Bisbee sees its pollen season open with palo verde and mesquite from January before mulberry peaks during February. Peak grass pollen arrives in March and April, and monsoon moisture from July through September brings a brief second wave of grass and weed pollen. The hot desert climate concentrates the main spring season, with little rainfall to interrupt pollen release.

When is pollen season in Bisbee?
How often is the Bisbee pollen forecast updated?
The Bisbee pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Bisbee 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 Bisbee 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 Bisbee, 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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
