Local Environmental Conditions
Here, a short distance from here, hazel and willow grow along the bank, contributing some of the season's earliest allergenic pollen. Nearby, within the neighborhood's edge, a stand of oak and birch, the latter ranked among the region's most potent tree allergens. Located in the surrounding area, this area has parkland with regularly mown grass and planted trees, both sources of grass and ragweed pollen.
The bank's hazel and willow kick off the pollen season ahead of the rest, reaching its high point sometime in late winter or early spring. The woodland's oak and birch trees become the main pollen source by mid-spring, peaking in the heart of spring, generally April into May. Grass pollen becomes the dominant allergen through late spring, peaking in June, then gives way to ragweed, which drives the season's second major surge from mid-August into October.

How often is the Wood River pollen forecast updated?

Does pollen in Wood River 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 Wood River 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 Wood River, 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. |
