Local Environmental Conditions
This area, close by, has the waterway's edge supports river oak, a species whose fine pollen travels well beyond the immediate bank. Eucalypt and wattle growing together, with wattle's fine pollen especially potent during its short flowering window; this sits close by. The broader area tends to mirror this pattern, with only minor local variation.
River oak near the water opens the pollen calendar early, peaking in mid-winter through September. Eucalypt and wattle nearby take over the pollen calendar through late winter, reaching its high point through August and into October. Grass pollen builds through spring and peaks in November, with levels staying elevated into the new year before finally easing off.

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