Local Environmental Conditions
River oak grows along the bank here, releasing fine wind-borne pollen typical of casuarina species, within the local area. This area, not far from here, has forest where eucalypt and wattle share the canopy and margins, wattle driving most of the seasonal pollen spike. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall.
Along the waterway, river oak releases pollen first, climbing steadily from mid-winter into September. Woodland eucalypt and wattle pick up the pace next, through late winter into spring, cresting around August and September in the year's sharpest tree-pollen spike. Grass pollen becomes the dominant allergen through spring, peaking in November, and remaining a significant allergen right through summer until it eases in February.

How often is the Flowerdale pollen forecast updated?

Does pollen in Flowerdale 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 Flowerdale 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 Flowerdale, 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. |
