Local Environmental Conditions
Water here is bordered by hazel and willow, both notable sources of wind-borne pollen; this sits near this part of town. Located close by, this area has woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen. Grass and ornamental trees within the park boundary contribute modestly to grass and ragweed levels, in the vicinity.
Hazel and willow by the water are typically first out of the gate, peaking in late winter through March. The woodland's oak and birch trees become the main pollen source by mid-spring, building to its sharpest point across April and May. Grass pollen rises through late spring toward a June high point, before ragweed's late-summer surge carries the season into October.

How often is the Mount Gilead pollen forecast updated?

Does pollen in Mount Gilead 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 Mount Gilead 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 Mount Gilead, 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. |
