Local Environmental Conditions
Here, just around the area, a stand of river oak lines the water, a reliable source of casuarina pollen through the warmer months. Nearby, within the local area, a stand of eucalypt with wattle through the understorey, wattle ranked among the region's sharpest allergens. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall.
The water-adjacent river oak is an early riser, usually peaking sometime between July and September. Eucalypt and wattle nearby take over the pollen calendar through late winter, building to its sharpest point across August and September. Spring brings rising grass pollen that crests in November, before pollen counts gradually decline through January and February.

How often is the Walcha pollen forecast updated?

Does pollen in Walcha 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 Walcha 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 Walcha, 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. |
