Local Environmental Conditions
Most of the area around this part of Hill River is woodland, with a good deal of scrubland. With this much woodland around, trees are an important local pollen source. Grasses also feature strongly, alongside pigweed among the weeds. In the immediate area, scrubland contributes pollen from shrubs, grasses and herbs.
Flowering trees bring the first pollen of the year in early spring. Grasses take over in mid-spring, with temperatures around 20°C, and their pollen lingers into mid-fall. Pigweed brings a final peak from early summer into early fall. Rain is heaviest in winter, often giving short breaks from high pollen levels.

Does pollen in Hill 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 Hill 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 Hill 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 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. |
