Local Environmental Conditions
This location in La Junta is surrounded mainly by built-up land, which covers around 57% of the nearby area, with a good deal of open grassland. Lawns and planted trees in a nearby park add to local grass and tree pollen. There is plenty of grass pollen here too. Locally, street trees, gardens and lawns supply most pollen in the built-up parts.
Through the seasons, woodland and street trees lead off, with tree pollen peaking around mid-spring. Grass pollen builds from mid-spring, peaks around early summer and stays noticeable until late summer. Later, weeds flowering on open and disturbed ground keep some pollen in the air from early summer into early fall. Here, winters average around freezing and summers around 25°C, with most rain falling in the warmer months.

Does pollen in La Junta 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 La Junta 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 La Junta, 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.

| 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. |
