Local Environmental Conditions
This site in Sydney CBD sits among a blend of open water and built-up land, plus some woodland. Among allergenic trees nearby, plane tree leads, followed by olive and oak. Grass pollen is significant here, and pellitory and pigweed contribute weed pollen. Pellitory is unusually common here compared with most other locations, making it a particularly important local pollen source.
Plane tree, olive and oak lead the season in early spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Then come the grasses, strongest in mid-spring and fading by mid-fall. The most intense period comes from late winter into early winter, when pellitory and pigweed are in flower. In warm, humid weather from midsummer into early fall, mold spores add to the mix, especially after rain.

How often is the Sydney CBD pollen forecast updated?

Does pollen in Sydney CBD 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 Sydney CBD 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 Sydney CBD, 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. |
