Local Environmental Conditions
Joplin's parks and the Spring River corridor feature oak, pine, and cedar as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Missouri and Kansas Ozark farmland and woodland contribute substantial tree and grass pollen, while the flat, open landscape allows pollen to disperse widely across the city under prevailing southwesterly winds.
Joplin's pollen season opens with cedar and elm from late January, followed by oak through March and April. Grass pollen peaks through May and June, with ragweed extending the season strongly into October. The Ozark plateau setting and surrounding Missouri and Kansas farmland contribute substantial tree and grass pollen, while the flat, open landscape allows pollen to disperse widely under prevailing southwesterly winds throughout the extended season.

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