Local Environmental Conditions
The nearest creek or river hosts river oak, among the most allergenic wind-pollinated trees found on watercourses, not far from here. Nearby, in the vicinity, a mix of eucalypt and wattle, wattle in particular a notorious trigger for hay fever across southern Australia. Nearby, within easy reach, parkland with regularly mown grass and planted plane trees, both sources of seasonal pollen.
River oak near the water opens the pollen calendar early, climbing steadily from mid-winter into September. The nearby eucalypt and wattle stands take the lead as winter turns to spring, peaking as wattle comes into full flower, generally August into September. Spring brings rising grass pollen that crests in November, with the season extending well into summer before finally winding down in February.

Does pollen in Winston Hills 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 Winston Hills 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 Winston Hills, 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. |
