Local Environmental Conditions
The landscape around this location in Meadow Vista is heavily wooded. The key allergenic tree nearby is oak. Gaps in the canopy, trails and forest edges give grasses and herbs room to grow. Much of the pollen in dense woodland is released high in the canopy, where the wind carries it easily.
The pollen year opens with oak, peaking around mid-spring. Grasses take over from mid-spring, with the highest levels around late spring and pollen lingering until midsummer. Weeds on open ground add a smaller late peak from early summer into early fall. Here, winters average around 10°C and summers around 30°C, with most rain falling in the cooler months.

Does pollen in Meadow Vista 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 Meadow Vista 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 Meadow Vista, 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. |
