Local Environmental Conditions
This area, close to this spot, has the riverbank shelters river oak, whose pollen spreads readily on the wind from spring onward. Nearby, close to home here, a stand of eucalypt with wattle through the understorey, wattle ranked among the region's sharpest allergens. Ground-level conditions like local landscaping can nudge these figures slightly either way.
Near the bank, river oak leads the seasonal calendar, usually the first pollen source active, peaking sometime in July or August. As spring approaches, eucalypt and wattle in the nearby woodland become the dominant source, climbing steadily through late winter to a peak in August or September. Spring brings rising grass pollen that crests in November, before continuing at a lower but still notable level through January and February.

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 Riddells Creek, 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. |
