Local Environmental Conditions
The area around this site in Jenolan is heavily wooded. With running water close by, riverside vegetation contributes to the local mix. So much tree cover makes trees an important source of pollen locally. Beyond the trees, grasses matter a great deal, and pigweed is the main weed source. Gaps in the canopy, trails and forest edges give grasses and herbs room to grow.
Flowering trees bring the first pollen of the year in early spring. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into late summer. Pigweed brings a final peak from early summer into early fall. Fall is the wettest time of year, and heavy showers can bring short breaks in pollen. By early winter, as temperatures fall to around 5°C, pollen levels are low again.

Does pollen in Jenolan 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 Jenolan 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 Jenolan, 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. |
