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. A stand of eucalypt with wattle through the understorey, wattle ranked among the region's sharpest allergens, within the neighborhood. This area, close by, has a park where mown turf grass and ornamental plane trees add to local grass and tree pollen.
River oak near the water opens the pollen calendar early, peaking in mid-winter through September. Eucalypt and wattle in the nearby woodland follow through late winter and early spring, reaching maximum intensity across the August-September window. By late spring, grass pollen is climbing steadily toward a November high point, holding through the summer months before tapering off by late February.

Does pollen in Merredin 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 Merredin 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 Merredin, 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. |
