Local Environmental Conditions
The landscape around the heart of Harcourt North is heavily wooded. The damp ground beside a watercourse nearby supports trees, shrubs and reeds, adding to local pollen. So much tree cover makes trees an important source of pollen locally. Grass pollen is significant here, and plantain contributes weed pollen. Gaps in the canopy, trails and forest edges give grasses and herbs room to grow.
Flowering trees bring the first pollen of the year in early spring. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. The season closes with plantain from mid-spring into early fall. Rain is heaviest in summer, often giving short breaks from high pollen levels. By early winter, as temperatures fall to around 5°C, pollen levels are low again.

Does pollen in Harcourt North 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 Harcourt North 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 Harcourt North, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
