Local Environmental Conditions
The center of Dalzell sits among a blend of woodland and farmland, plus some open grassland. Along a watercourse nearby, trees, shrubs and reeds grow in the damper ground and add their own pollen. So much tree cover makes trees an important source of pollen locally. Grass pollen adds noticeably to the overall load.
Flowering trees bring the first pollen of the year in mid-spring. Grasses take over in late spring and keep pollen in the air into early fall. Weeds on open ground add a smaller late peak from early summer into early fall. Summer is the wettest time of year, and heavy showers can bring short breaks in pollen.

How often is the Dalzell pollen forecast updated?

Does pollen in Dalzell 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 Dalzell 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 Dalzell, 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. |
