Local Environmental Conditions
This site in Richmond is surrounded mainly by built-up land, with some woodland. Lawns and planted trees in a nearby park add to local grass and tree pollen. Oak heads the list of allergenic trees nearby, ahead of plane tree and maple. Compared with most places, oak is especially widespread here, which makes it one of the key local allergens.
Oak, plane tree and maple lead the season in mid-spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Then come the grasses, strongest in late spring and fading by early fall. Later, ragweed and plantain keep weed pollen in the air from late summer into mid-fall. The oak period in mid-spring is usually the most intense time of year here.

Does pollen in Richmond 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 Richmond 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 Richmond, 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.

| 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. |
