Local Environmental Conditions
Bourke, on the Darling River in the far west, is fringed by majestic river red gums along the watercourse, with the surrounding outback dominated by saltbush and chenopod shrubland and sparse native grasses; irrigated cotton fields near town add a further crop pollen source. Grass pollen typically becomes the dominant local allergen through late spring and into summer, following an earlier and comparatively brief peak from flowering wattle and eucalypt in the cooler months.
Bourke, on the Darling River at the edge of the outback, sits in one of NSW's driest and hottest districts, giving it an irregular, rainfall-dependent pollen season rather than a predictable spring peak. River red gums and coolibah along the Darling flower from late winter, while grass and chenopod pollen from the surrounding plains responds mainly to rain events, which can occur at any time of year. When good rains fall, spring still tends to bring the heaviest pollen loads, but drought years can suppress the season almost entirely.

How often is the Bourke pollen forecast updated?

Does pollen in Bourke 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 Bourke 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 Bourke, 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 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 exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
