ENVIRONMENT & ANALYSIS

Local Environmental Conditions

Nearby, in the wider area, the nearest stream or river hosts hazel and willow, two of the most allergenic early-season trees. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall. Local microclimate and soil conditions can push these figures slightly higher or lower. The broader area tends to mirror this pattern, with only minor local variation.

Hazel and willow by the water are typically first out of the gate, reaching its high point sometime in late winter or early spring. Grass pollen counts rise through late spring, reaching their peak around June, then gives way to ragweed, which drives the season's second major surge from mid-August into October.

How often is the Plainfield Township pollen forecast updated?

Does pollen in Plainfield Township 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 Plainfield Township 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 Plainfield Township, 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.
