Local Environmental Conditions
Nearby, within the neighborhood, the nearest creek or river hosts river oak, among the most allergenic wind-pollinated trees found on watercourses. The general pattern described here holds fairly steady across nearby areas with similar land cover. Local wind exposure and land use can shift the exact mix slightly from block to block.
The water-adjacent river oak is an early riser, topping out well before most other trees start releasing pollen, around July and August. Grass pollen becomes the dominant allergen through spring, peaking in November, before staying elevated through the summer months into late January. Neighboring parts of the region typically see this same sequence with only minor timing shifts.

How often is the Cape Arid pollen forecast updated?
The Cape Arid pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Cape Arid 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 Cape Arid 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 Cape Arid, 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. |
