Local Environmental Conditions
This area, within easy reach, has forest where plane tree and eucalypt make up much of the canopy, driving spring pollen counts. 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. Nearby weather stations report comparable trends across the broader stretch of the county.
In Worrolong, temperatures climbing to 12.5°C by September likely mark the start of the main pollen release, with humidity around 77% helping keep counts airborne. Warmer conditions by December (16.2°C, 72% humidity) sustain grass pollen through the season, before rainfall of 40mm in March and cooling toward 11.8°C in June bring the season to a close.

How often is the The District Council of Grant pollen forecast updated?

Does pollen in The District Council of Grant come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. 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 The District Council of Grant 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 The District Council of Grant, 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. |
