Local Environmental Conditions
The heart of Ballan is surrounded mainly by open grassland, with some woodland. The damp ground beside a watercourse nearby supports trees, shrubs and reeds, adding to local pollen. Trees are an important local pollen source, given how much woodland surrounds the area. Grasses and weeds such as plantain round out the local mix.
Flowering trees bring the first pollen of the year in mid-spring. Then come the grasses, strongest in early summer and fading by late summer. The season closes with plantain from mid-spring into early fall. Rain is heaviest in spring, often giving short breaks from high pollen levels. By early winter, as temperatures fall to around 5°C, pollen levels are low again.

How often is the Ballan pollen forecast updated?

Does pollen in Ballan 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 Ballan 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 Ballan, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
