Local Environmental Conditions
Around 57% of the area near the heart of Aci Catena is woodland, with a good deal of built-up land. Woodland on all sides makes trees an important local pollen source. In the built-up parts of the area, street trees, gardens and park lawns add to the local mix. Roadside verges and patches of open ground provide further room for grasses and weeds.
Tree pollen comes first, peaking in early spring. Then come the grasses, strongest in late spring and fading by early fall. Spring is the wettest time of year, and heavy showers can bring short breaks in pollen. Day to day, sunshine and wind lift the counts, while a spell of rain can bring them down sharply.

Does pollen in Aci Catena come from nearby or far away?

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Aci Catena 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 Aci Catena, 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. |
