Local Environmental Conditions
This part of Blackhawk sits among a blend of built-up land and woodland, plus some open grassland. Oak stands out as the main allergenic tree nearby. Beyond the trees, grasses matter a great deal, and mugwort is the main weed source. Compared with most places, oak is especially widespread here, which makes it one of the key local allergens.
Tree pollen peaks in mid-spring, when the weather warms to around 15°C and oak is in full flower. Then come the grasses, strongest in late spring and fading by early fall. Later, mugwort keeps weed pollen in the air through summer. The oak period in mid-spring is usually the most intense time of year here. Rain is heaviest in winter, often giving short breaks from high pollen levels.

Does pollen in Blackhawk 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 Blackhawk 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 Blackhawk, 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. |
