Local Environmental Conditions
River oak thrives along the damp bank, a classic riparian wind-pollinator in this part of Australia; this sits just around the area. Nearby, close to home here, forest where eucalypt and wattle share the canopy and margins, wattle driving most of the seasonal pollen spike. Parkland with regularly mown grass and planted plane trees, both sources of seasonal pollen; this sits close to this spot.
Along the waterway, river oak releases pollen first, usually peaking sometime between July and September. Once river oak fades, eucalypt and wattle in the woods carry the season forward, reaching its high point through August and into October. Grass pollen takes over next, building to a peak around November, before staying elevated through the summer months into late January.

Does pollen in Dee Why 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 Dee Why 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 Dee Why, 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. |
