Local Environmental Conditions
Here, a short distance from here, the waterway's edge supports river oak, a species whose fine pollen travels well beyond the immediate bank. Eucalypt dominating the treeline with wattle scattered through it, both contributing to the season's pollen load, a short distance from here. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
Near the bank, river oak leads the seasonal calendar, reaching its high point sometime in late winter or early spring. The nearby eucalypt and wattle stands take the lead as winter turns to spring, reaching its high point through August and into October. Grass pollen rises through spring toward a November high point, holding through the summer months before tapering off by late February.

How often is the Kalgan pollen forecast updated?

Does pollen in Kalgan 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 Kalgan 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 Kalgan, 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. |
