Local Environmental Conditions
Mittagong, in the cool Southern Highlands, favours introduced deciduous species over coastal natives: oaks, elms, maples and poplars fill both public parks and private gardens, giving the town a strong autumn-exotic character. Surrounding bushland is dry sclerophyll eucalypt forest with peppermint and stringybark, and grazing paddocks carry temperate pasture grasses. Wattle flowers heavily in late winter along roadside verges. The elevation keeps flowering later than coastal NSW, shifting exotic tree pollen into early spring.
As one of the higher-altitude towns in the Southern Highlands, Mittagong tends to run its pollen season slightly later and cooler than towns on the coast or plains. Tree flowering, wattle, eucalypt and introduced garden species, builds from late August, with grass pollen from surrounding grazing land peaking in November. The elevation delays onset by a week or two some years, but once underway the highlands' cooler, moister air can keep grass pollen airborne longer into summer.

When is pollen season in Mittagong?
How often is the Mittagong pollen forecast updated?

Does pollen in Mittagong 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 Mittagong 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 Mittagong, 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. |
