Local Environmental Conditions
Adelaide's vegetation reflects its Mediterranean setting, with eucalypt woodland and wattle across the Adelaide Hills and Adelaide Plains, plus extensive plantings of olives and grapevines in surrounding wine districts such as the Adelaide Hills and Barossa Valley. Coastal suburbs carry heath and scrubby vegetation, while the city's parklands and street trees add a mix of native and introduced species. Overall it's a mix of dry-adapted natives and Mediterranean agricultural crops.
Adelaide's pollen season is concentrated and intense, running roughly August through November as the Mediterranean climate's mild, wet winter gives way to a dry spring. Tree pollen, including introduced species around the Adelaide Plains, opens in August-September, followed by grass pollen from grazing land, parks and the surrounding Adelaide Hills through October and November. Long, hot, dry summers largely suppress pollen production, making the region's season notably shorter and sharper than in the subtropical east.

When is pollen season in Adelaide?
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. |
