Local Environmental Conditions
A stand of river oak lines the water, a reliable source of casuarina pollen through the warmer months, close to this spot. Here, a short distance from here, woodland where eucalypt stands alongside wattle, the latter especially aggressive as an allergen when in full flower. Seasonal timing here generally tracks the wider region, give or take a week or so.
River oak near the water opens the pollen calendar early, climbing steadily from mid-winter into September. Eucalypt and wattle nearby take over the pollen calendar through late winter, cresting around August and September in the year's sharpest tree-pollen spike. Grass pollen takes over next, building to a peak around November, then persisting at a reduced but still meaningful level into the new year.

How often is the Cattai pollen forecast updated?

Does pollen in Cattai 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 Cattai 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 Cattai, 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. |
