Local Environmental Conditions
This area, in the surrounding area, has wattle and casuarina cluster near the water, an early and reliable source of allergenic pollen. Local wind exposure and land use can shift the exact mix slightly from block to block. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
In Aurville, temperatures climbing to 11.9°C by September likely mark the start of the main pollen release, with humidity around 67% helping keep counts airborne. Warmer conditions by December (21.7°C, 53% humidity) sustain grass pollen through the season, before rainfall of 66mm in March and cooling toward 7.4°C in June bring the season to a close.

Does pollen in Hilltops Council come from nearby or far away?

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 Hilltops Council 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 Hilltops Council, 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. |
