Local Environmental Conditions
This area, not far from here, has river oak thrives along the damp bank, a classic riparian wind-pollinator in this part of Australia. This area, close to this spot, has forest where eucalypt and wattle share the canopy and margins, wattle driving most of the seasonal pollen spike. Surrounding neighborhoods with similar tree cover typically see a closely comparable pollen mix.
Water-edge river oak is usually the first allergenic tree active here, reaching its high point sometime in late winter or early spring. The area's eucalypt and wattle trees pollinate through late winter and early spring, usually hitting its highest point sometime between mid-August and mid-September. Grass pollen becomes the dominant allergen through spring, peaking in November, and remaining a significant allergen right through summer until it eases in February.

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