Local Environmental Conditions
This area, some 450 meters out, has hazel and willow thrive along the damp bank, both prolific early wind-pollinators. Forest where oak and birch make up much of the canopy, driving spring pollen counts, within easy reach at 300m. A park combining lawn grass and planted trees, both minor but real contributors to pollen here; this sits reasonably near, about 300-400 meters out.
Near the bank, hazel and willow lead the seasonal calendar, usually the first pollen source active, peaking sometime in February or March. The woodland's oak and birch trees become the main pollen source by mid-spring, cresting around April and May in the year's sharpest tree-pollen spike. As spring turns to summer, grass pollen rises toward its June high, with ragweed climbing to its own high point from mid-August through October.

When is pollen season in Warren?
How often is the Warren pollen forecast updated?

Does pollen in Warren 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 Warren 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 Warren, 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. |
