Local Environmental Conditions
The area around this location in Holden is heavily wooded, with some built-up land. Close to a watercourse, riverside vegetation contributes to what is in the air. Maple heads the list of allergenic trees nearby, ahead of oak and birch. Clearings, tracks and woodland edges let grasses and other flowering plants grow among the trees.
Tree pollen peaks in mid-spring, when the weather warms to around 10°C and maple, oak and birch are in full flower. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. By late fall, pollen levels are low again. Actual levels on any given day depend on the weather, with dry, breezy days the worst and wet days the mildest.

How often is the Holden pollen forecast updated?
The Holden pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Holden 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 Holden 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 Holden, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
