Local Environmental Conditions
With little in the way of woodland, water, or green space close by, grass is the more likely driver of pollen here. Actual counts still shift year to year with temperature, rainfall, and prevailing wind. Local readings for the surrounding area tend to follow this same general pattern. Ground-level conditions like local landscaping can nudge these figures slightly either way.
For Western Flora Caravan Park, grass pollen counts rise through spring, reaching their peak around November, then holding at a high level well into January before easing off. Year-to-year timing varies a little, though the general sequence stays fairly consistent here. Actual peak timing can drift earlier or later depending on how the season's weather plays out.

How often is the Arrowsmith pollen forecast updated?

Does pollen in Arrowsmith 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 Arrowsmith 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 Arrowsmith, 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. |
