Local Environmental Conditions
The heart of Orchard Mesa sits in a varied landscape of built-up land, woodland and scrubland. Along running water nearby, trees, shrubs and reeds grow in the damper ground and add their own pollen. The surrounding woodland makes trees an important local pollen source. Grasses are a major source, with pigweed adding to the weed pollen load.
Flowering trees bring the first pollen of the year in mid-spring. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Pigweed brings a final peak from early summer into early fall. In this dry climate, pollen can linger in the air for long spells without rain. By late fall, as temperatures fall to around 5°C, pollen levels are low again.

Does pollen in Orchard Mesa 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 Orchard Mesa 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 Orchard Mesa, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
