Local Environmental Conditions
Without notable forest, water, or parkland close by, roadside and field grasses along with plantain and weed are the more likely dominant pollen sources here. Year-to-year swings in rainfall and wind can shift this picture somewhat either way. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall.
Late spring sees grass pollen build steadily toward a peak in December, before plantain and weed takes over as the dominant allergen from mid-February through April. Year-to-year timing varies a little, though the general sequence stays fairly consistent here. Actual peak timing can drift earlier or later depending on how the season's weather plays out.

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. |
