Local Environmental Conditions
Hahndorf, in the Adelaide Hills, is a historic German-settled town known for its cool-climate exotic deciduous trees, oaks, elms and maples, planted through its heritage streetscape, alongside surrounding orchards and cool-climate vineyards. Remnant native eucalypt forest covers uncleared hill country nearby. The elevated hills climate gives Hahndorf a later, more pronounced exotic-tree flowering season than Adelaide's plains suburbs.
Hahndorf's elevated Adelaide Hills position, similar to nearby Stirling, gives it a cooler and slightly later pollen season than the Adelaide plain, wattle and eucalypt flowering from late August and grass pollen from the surrounding pasture peaking in October. The Hills' cooler, moister climate can sustain grass growth a little longer into the season than the hotter, drier plain below. The town's historic gardens and orchard plantings add a further layer of tree pollen through the spring build.

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