Local Environmental Conditions
Here, a short distance from here, river oak grows along the bank here, releasing fine wind-borne pollen typical of casuarina species. This area, in the surrounding area, has tree cover made up mostly of eucalypt and wattle, wattle in particular a well-known seasonal trigger. Mown grass and planted plane trees in a nearby park, adding to the seasonal pollen mix, close by.
River oak by the water is typically first out of the gate, reaching its high point sometime in late winter or early spring. The woodland's eucalypt and wattle trees become the main pollen source as wattle flowers, typically the year's sharpest tree-pollen spell, centered on wattle's flowering in August and September. Grass pollen rises through spring toward a November high point, before pollen counts gradually decline through January and February.

Does pollen in Kalamunda 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 Kalamunda 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 Kalamunda, 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. |
