Local Environmental Conditions
Lacking nearby woodland, water, or green space, this area's pollen load leans almost entirely on wild grass rather than tree species. The general pattern described here holds fairly steady across nearby areas with similar land cover. Local wind exposure and land use can shift the exact mix slightly from block to block.
As spring turns to summer, grass pollen rises toward its November high, before staying elevated through the summer months into late January. Actual peak timing can drift earlier or later depending on how the season's weather plays out. Neighboring parts of the region typically see this same sequence with only minor timing shifts.

How often is the Trawalla pollen forecast updated?
The Trawalla pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Trawalla 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 Trawalla 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 Trawalla, 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 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
