Local Environmental Conditions
In Rainy Lake RV, located just around the area, this area has the waterside growth here is largely hazel and willow, both efficient wind-pollen dispersers. Local microclimate and soil conditions can push these figures slightly higher or lower. The broader area tends to mirror this pattern, with only minor local variation.
In Rainy Lake RV, near the bank, hazel and willow lead the seasonal calendar, topping out well before most other trees start releasing pollen, around February and March. Moving into early summer, grass pollen climbs to its seasonal high in June, before ragweed's late-summer surge carries the season into October.

Does pollen in Rainy Lake RV 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 Rainy Lake RV 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 Rainy Lake RV, 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. |
