Local Environmental Conditions
Nearby, not far from here, river oak lines the bank, contributing some of the season's more persistent wind-borne pollen. Nearby, close by, woods composed largely of eucalypt with wattle at the margins, a combination tied to sharp late-winter pollen spikes. Here, within the local area, green space with maintained lawn and planted plane trees, both contributing to seasonal pollen counts.
Near the bank, river oak leads the seasonal calendar, climbing steadily from mid-winter into September. By late winter, eucalypt and wattle in the woods take over, climbing steadily through late winter to a peak in August or September. Grass pollen builds through spring and peaks in November, then holding at a high level well into January before easing off.

Does pollen in Katoomba 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 Katoomba 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 Katoomba, 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. |
