Local Environmental Conditions
This area, close to home here, has water here is bordered by river oak, a casuarina species known for prolific, far-carrying pollen. Actual counts still shift year to year with temperature, rainfall, and prevailing wind. Local readings for the surrounding area tend to follow this same general pattern. Ground-level conditions like local landscaping can nudge these figures slightly either way.
The water-adjacent river oak is an early riser, peaking in mid-winter through September. Grass pollen counts rise through spring, reaching their peak around November, before pollen counts gradually decline through January and February. This general pattern holds fairly steady across the surrounding region from year to year. Local weather swings can shift these windows slightly, but the overall order tends to hold.

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