Local Environmental Conditions
The center of Katoomba is surrounded mainly by woodland, which covers around 65% of the nearby area, with a good deal of built-up land. Lawns and planted trees in a nearby park add to local grass and tree pollen. Willow heads the list of allergenic trees nearby, ahead of plane tree. Beyond the trees, grasses matter a great deal, and plantain is the main weed source.
Willow and plane tree lead the season in early spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into late summer. Plantain brings a final peak from mid-spring into early fall. Fall is the wettest time of year, and heavy showers can bring short breaks in pollen.

How often is the Katoomba pollen forecast updated?

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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
