Local Environmental Conditions
Here, just around the area, river oak thrives along the damp bank, a classic riparian wind-pollinator in this part of Australia. Here, close to home here, eucalypt dominating the treeline with wattle scattered through it, both contributing to the season's pollen load. Neighboring areas with similar land cover tend to show a closely matching pollen mix.
River oak along the water gets the season underway before other species, topping out well before most other trees start releasing pollen, around July and August. Once river oak fades, eucalypt and wattle in the woods carry the season forward, typically the year's sharpest tree-pollen spell, centered on wattle's flowering in August and September. By late spring, grass pollen is climbing steadily toward a November high point, with levels staying elevated into the new year before finally easing off.

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