Local Environmental Conditions
Here, near this part of town, river oak lines the bank, contributing some of the season's more persistent wind-borne pollen. Woodland where eucalypt stands alongside wattle, the latter especially aggressive as an allergen when in full flower; this sits within easy reach. Neighboring areas with similar land cover tend to show a closely matching pollen mix.
In Redgum Campsite, once river oak fades, eucalypt and wattle in the woods carry the season forward, usually hitting its highest point sometime between mid-August and mid-September. Grass pollen counts rise through spring, reaching their peak around November, and remaining a significant allergen right through summer until it eases in February.

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 Mount Portal 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 Mount Portal, 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.

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. |
