Local Environmental Conditions
Danada Farms — A waterway supports hazel and willow along its bank, both strongly allergenic wind-pollinated species, at around 318m distant. Oak and birch dominating the treeline, both heavy contributors to the spring pollen load; this sits a short 129 meters out. Here, some 695 meters to the edge of the area, a park whose turf grass and ornamental plantings feed local grass and ragweed pollen levels.
Near the bank, hazel and willow lead the seasonal calendar, building through the tail end of winter into March. By mid-spring, oak and birch in the woods take over, building to its sharpest point across April and May. Through late spring, grass pollen climbs steadily toward its June peak, before ragweed becomes the more dominant allergen from mid-August into October.

How often is the Wheaton pollen forecast updated?

Does pollen in Wheaton 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 Wheaton 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 Wheaton, 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 exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
