Local Environmental Conditions
Here, close by, river oak thrives along the damp bank, a classic riparian wind-pollinator in this part of Australia. This area, in the wider area, has woodland where eucalypt stands alongside wattle, the latter especially aggressive as an allergen when in full flower. Located in the surrounding area, this area has mown grass and planted plane trees in a nearby park, adding to the seasonal pollen mix.
Water-edge river oak is usually the first allergenic tree active here, starting well before the main spring rush, topping out around September. The nearby eucalypt and wattle stands take the lead as winter turns to spring, usually peaking from August into October. Grass pollen climbs toward a November peak, then holding at a high level well into January before easing off.

How often is the Flagstaff Hill pollen forecast updated?
The Flagstaff Hill pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Flagstaff Hill 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 Flagstaff Hill 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 Flagstaff Hill, 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/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. |
