Local Environmental Conditions
Here, just around the area, river oak thrives along the damp bank, a classic riparian wind-pollinator in this part of Australia. Woodland where eucalypt stands alongside wattle, the latter especially aggressive as an allergen when in full flower; this sits close to home here. Nearby, in the surrounding area, a park combining lawn grass and plane trees, both contributors to pollen here through the warmer months.
The bank's river oak kicks off the pollen season ahead of the rest, usually peaking sometime between July and September. Eucalypt and wattle nearby take over the pollen calendar through late winter, climbing steadily through late winter to a peak in August or September. Grass pollen becomes the dominant allergen through spring, peaking in November, and remaining a significant allergen right through summer until it eases in February.

Does pollen in Double Bay 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 Double Bay 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 Double Bay, 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. |
