Local Environmental Conditions
Pairie Ridge — The waterway's edge supports hazel and willow, species known for potent, wind-carried pollen; this sits just over 133 meters from the neighborhood. Here, just 237m from here, oak and birch dominating the treeline, both heavy contributors to the spring pollen load. Here, barely 125 meters away, mown grass and ornamental trees in a nearby park, adding to seasonal grass and ragweed pollen.
Water-edge hazel and willow are usually the first allergenic trees active here, building through the tail end of winter into March. By mid-spring, oak and birch in the woods take over, topping out in the April-to-May stretch. Through late spring, grass pollen climbs steadily toward its June peak, then gives way to ragweed, which drives the season's second major surge from mid-August into October.

How often is the Pairie Ridge pollen forecast updated?

Does pollen in Pairie Ridge 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 Pairie Ridge 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 Pairie Ridge, 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. |
