Local Environmental Conditions
The area around this site in Saint James City is mostly open water. Close to a stream or river, riverside vegetation contributes to what is in the air. With much of the immediate area made up of open water, local pollen production is limited, though pollen can still drift in from surrounding land. Grasses, ragweed and pigweed growing in the surroundings are the main non-tree sources of pollen.
Grass pollen follows, peaking in mid-spring and easing off by late fall. Ragweed and pigweed bring a final peak from late summer into mid-fall. Warm, humid weather keeps mold spores around for most of the year as well. Actual levels on any given day depend on the weather, with dry, breezy days the worst and wet days the mildest.

How often is the Saint James City pollen forecast updated?

Does pollen in Saint James City 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 Saint James City 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 Saint James City, 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. |
